fix(build-test-sonar)!: Authenticate Sonar scanner with sonar.token - #3
Conversation
The action supplied the SonarCloud credential only as the sonar.login analysis property. sonar.login was deprecated in favour of sonar.token and is no longer honoured by the current SonarScanner engine, so the scanner authenticated anonymously and post-processing failed at "Create analysis" with a misleading "Not authorized or project not found". Because the token was interpolated successfully, this failed silently rather than erroring on a missing input. Set SONAR_TOKEN as an environment variable on the begin and end steps, which the scanner reads natively, and migrate the property name to sonar.token. Both steps keep shell: pwsh, so the value is referenced as $env:SONAR_TOKEN; a bare $SONAR_TOKEN is bash syntax and would expand to an empty string under pwsh, reintroducing the same anonymous-auth bug in a new form. Also: - Add a Validate SonarCloud Token step that fails fast with a workflow error annotation when the input is empty, instead of proceeding anonymously. GitHub does not enforce required: true for composite action inputs at runtime, so an empty secret previously sailed through. Only the token length is logged, never the value. - Stop writing the token into the Action Properties log line. Registered secrets are masked, but a token supplied through a non-secret path would have been printed in clear text. - Update actions/setup-dotnet v3 to v6 and actions/setup-java v4 to v5. v4 of setup-dotnet was also stale and still runs on a Node runtime heading for deprecation, so it would have re-created the warning this change is meant to clear. - Remove the dead outputs.random-number block, a leftover from the action template that referenced a non-existent step and always evaluated to an empty string. - Document the dotnet-version default rather than changing it, so no consumer's SDK selection shifts under them. - Apply the same sonar.token migration to build-test-snar-ps/build-test-sonar.ps1, whose begin line also referenced an undefined $sonarToken. That script is not currently wired to any action. BREAKING CHANGE: actions/setup-dotnet v6 and actions/setup-java v5 run on the Node 24 runtime and require a runner at v2.327.1 or newer. GitHub-hosted runners satisfy this automatically; self-hosted runners must be updated. The unused random-number output is also no longer declared. Refs: #1

Address review findings on PR #3. Because dotnet-version carries a default, the action always passes it to actions/setup-dotnet, which therefore never falls back to a global.json in the consuming repository. The input description said consumers could "commit a global.json" as an alternative to setting the input, which is wrong. Reword it to state plainly that the value is always passed and must be set explicitly for other target frameworks. The default is unchanged at 9.0.x, and the input stays optional, so no consumer's SDK selection shifts. Add the same empty-token guard to build-test-snar-ps/build-test-sonar.ps1 that the composite action now has. Without it the script expanded an empty token and ran the scanner anonymously, failing later with the same misleading authorisation error this branch exists to fix. Refs: #1

The scanner install, begin and end steps carried continue-on-error, so a SonarCloud failure produced a green job. That undercut the completion gate in .claude/rules/pr-checks-completion-gate.md, which requires the SonarCloud verdict to be a real gate condition — a silently-skipped analysis read as a passing one. The credential was also still passed as the deprecated sonar.login property, which the current scanner engine ignores; it therefore authenticated anonymously and failed post-processing with a misleading 'Not authorized or project not found'. Masked by continue-on-error, this had gone unnoticed. Same defect fixed for the shared composite action in mrploch/ploch-github-actions#3. Adds a sonar-eligibility gate so the scanner steps are skipped, not failed, when GitHub withholds secrets — pull requests from forks and those authored by Dependabot, whose branch lives in this repository and so is not caught by a head.repo test alone. Build and Test remain ungated and run in every case. SonarScanner End now uses !cancelled() rather than always(), so a cancelled run no longer attempts to close out an analysis. Refs: #296

Refs: #296 * fix(workflows): Keep build and test running after SonarCloud failures Removing continue-on-error made a Sonar failure halt the job, so a failed eligibility check or a failed scanner install/begin skipped Build and Test entirely — trading a masked Sonar failure for a lost compile-and-test signal, which is the more valuable of the two. Build and Test now carry if: !cancelled(), so they run regardless of what happened upstream. The Sonar failure still fails the job; it just no longer suppresses the result that matters most. Also strips all whitespace rather than literal spaces when testing the token, so a token consisting only of tabs or newlines is treated as absent instead of enabling the scanner with an invalid credential. Raised by Sourcery (broader_impact, bug_risk) and Codex (P2) on PR #297. Refs: #296 * ci(workflows): Tie Build and Test to their real prerequisites Follow-up hardening on the SonarCloud unmasking. Three gaps remained after removing continue-on-error. !cancelled() overrides the implicit success() for *every* preceding step, not just the Sonar block, so the bare form introduced earlier would run Build after a failed checkout, .NET setup or restore - producing a missing-input error instead of a compile signal. Build now also requires steps.restore.outcome == 'success', which keeps it tied to what it actually needs while staying independent of everything in the Sonar block. Test runs with --no-build, so a failed Build previously produced a second, more confusing failure about missing assemblies rather than the compile error itself. Test now requires steps.build.outcome == 'success'. Raised by Codacy on PR #297. The eligibility check only recognised withheld secrets on pull_request events, so a fork's own push or a workflow_dispatch run fell through to the error branch and failed the job. Analysis is now skipped outright outside mrploch/ploch-common: the project key belongs to upstream, so a fork could not usefully analyse into it even with its own token. Verified by simulating the eligibility script across all twelve combinations of upstream x {real token, empty, whitespace-only} x secrets-withheld: upstream with a token enables analysis; upstream without one warns and continues when secrets are legitimately withheld and fails loudly otherwise; outside upstream always warns and continues. bash -n clean, YAML parses, and every steps.<id> reference resolves to a step defined earlier in the job. Refs: #296 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci(workflows): Fail loudly when the packages token is missing upstream Removing the SonarCloud masking exposed a second instance of the same pattern one step further down the job. Both GitHub Packages steps guarded an empty GH_PACKAGES_TOKEN by warning and exiting 0. That guard exists because a fork's own master/main push now reaches these steps at all - the eligibility check skips rather than fails, so success() stays true - but it applied to the upstream repository too. A push to mrploch/ploch-common with the secret missing would have reported a green build while silently publishing nothing, which is precisely the masked failure this branch set out to remove. The guard is now three-way: skip with a warning outside mrploch/ploch-common, fail with an error inside it. The publish step carries the same guard as the source step. Upstream with an empty token it is unreachable, because the source step fails first and success() is then false, but the two are kept symmetrical so neither can be read as the lenient one. Verified by simulation: upstream with an empty token exits 1 and emits ::error::; a fork with an empty token exits 0 and emits ::warning::; a present token proceeds. bash -n clean, YAML parses. Also documents a consequence of the Build gate: because it names its prerequisite explicitly, a step inserted between Restore and Build will not halt Build unless it is given an id and added to the condition. Raised by Codex (packages token) and Antigravity (Build gate comment) during external review. Refs: #296 Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * ci(workflows): Skip GitHub Packages publish outside the upstream repo The guard added in the previous commit tested the token before the repository, so a fork that supplies its own GH_PACKAGES_TOKEN still reached `dotnet nuget push` and published against nuget.pkg.github.com/mrploch - upstream's feed, which it has no business writing to. The repository check now comes first, matching the order already used by the SonarCloud eligibility step and for the same reason: the destination belongs to upstream, so a fork must skip regardless of what credentials it happens to hold. Upstream behaviour is unchanged - a missing token there is still a hard error rather than a silent skip. Verified by simulation across all four combinations: outside the upstream repository both an empty and a populated token warn and exit 0; upstream an empty token exits 1 with ::error:: and a populated one proceeds.

Summary
build-test-sonarsupplied the SonarCloud credential only as thesonar.loginanalysis property.sonar.loginwas deprecated in favour ofsonar.tokenand is no longer honoured by the current SonarScanner engine, so the scanner authenticated anonymously and post-processing failed atCreate analysiswith a misleadingNot authorized or project not found.Because the token was interpolated correctly (it appears masked as
***in run logs), this failed silently rather than erroring on a missing input, which is why it read as an account/permissions problem and sent people to the SonarCloud administration screens.Every repository consuming
build-test-sonar@mainwas getting no SonarCloud analysis and a permanently red build.Changes
The fix -
SONAR_TOKENis now set as an environment variable on both scanner steps (the scanner reads it natively), and the property name is migrated tosonar.token:Alongside it:
Validate SonarCloud Tokenstep is the first step in the action and exits1with a::error::annotation when the input is blank. GitHub does not enforcerequired: truefor composite-action inputs at runtime, so an empty secret previously sailed straight through into an anonymous analysis. Only the token length is logged, never the value. This is the change that would have made the original bug obvious in minutes.Action Propertiesprinted the token after aLogin:label. Registered secrets are masked, but a token supplied through a non-secret path (avarsvalue, a literal) would have been printed in clear text.actions/setup-dotnet@v3to@v6andactions/setup-java@v4to@v5(see Design Decisions).outputs.random-numberblock - a leftover from the action template that referenced a non-existent steprandom-number-generatorand always evaluated to an empty string.dotnet-versiondefault instead of changing it (see Design Decisions).build-test-snar-ps/build-test-sonar.ps1had the samesonar.loginproblem, plus an undefined$sonarTokenvariable on its begin line. Both lines now usesonar.tokenwith$env:SONAR_TOKEN. That script is not currently wired to any action.Design Decisions
shell: pwshwas kept, and the token is referenced as$env:SONAR_TOKEN.This is the subtle part. A bare
$SONAR_TOKENis bash syntax; underpwshit is an undefined PowerShell variable that expands to an empty string, which would have reintroduced the exact same anonymous-auth bug in a new form. Verified empirically against pwsh 7.6.3 by passing the argument to a real native process and printing the argument vector it received:Switching the two steps to
shell: bashwas the alternative. Rejected: every other step in the action usespwsh, so it would have made the file inconsistent and changed cross-platform behaviour for a composite action that may run on Windows runners. Keepingpwshis the smaller, more conservative change.Both the env var and the
/d:property are set. Belt and braces:SONAR_TOKENis what the scanner engine reads natively (this is the difference the issue's evidence isolated), andsonar.tokenis the correct modern property name. Passing the secret viaenv:rather than interpolating it directly intorun:also follows GitHub's script-injection hardening guidance.setup-dotnetwent tov6, not thev4the issue suggested.v4is itself two majors stale and runs on a Node runtime already heading for deprecation, so moving tov4would have re-created the very deprecation warning this change is meant to clear. Checked the release notes for each intervening major:v4= Node 20 plus a sequential-install fix;v5= Node 24 plus removal of references to EOL .NET versions (verified via actions/setup-dotnet#647, a docs/tests/installer-script refresh, not a loss of install capability for supported SDKs);v6= ESM migration and dependency bumps with no functional breaking change. Same reasoning forsetup-java@v5(Node 24 plus bug fixes; this action pinsdistribution: zuluandjava-version: 17, so upstream default changes do not apply).The
dotnet-versiondefault was deliberately not changed. It stays at9.0.x. Changing a shared default ships instantly to every consumer at@mainand would silently shift SDK selection under repositories that are currently fine. Instead the input description now documents the behaviour and tells consumers targetingnet10.0to set it explicitly, rather than relying on whichever SDK the runner image happens to ship. Zero behaviour change. (The description originally also offeredglobal.jsonas an alternative; CodeRabbit correctly pointed out thatactions/setup-dotnetnever falls back toglobal.jsonwhiledotnet-versionis supplied, so that half was removed inbc2af89.)SHA-pinning was left out. None of the
uses:references are pinned to commit SHAs, which SonarCloud flags asgithubactions:S7637;Amadevus/pwsh-script@v2intest-script-actionis the genuinely third-party one. Left out here to keep this change minimal, and because pinning without Dependabot just trades one problem for another. Filed as #2.Testing
Verified:
action.yml/ workflow files in the repository parse as valid YAML (PyYAMLsafe_load);build-test-sonaryields the expected 11 steps.SONAR_TOKENwas programmatically cross-checked to confirm it declaresshell: pwsh, declares theenv:block, uses$env:syntax, and contains no bare$SONAR_TOKEN. All consistent.Validate SonarCloud Tokenstep body executed under pwsh across four cases: unset gives exit 1, empty string gives exit 1, whitespace-only gives exit 1, valid token gives exit 0 printing only the length. The token value is never echoed.grepconfirms nosonar.loginremains anywhere in the repository.Reasoned but not executed - a composite action cannot be fully integration-tested without a consuming build, and this repository has no CI workflow that exercises
build-test-sonar(run-test-action.ymlisworkflow_dispatchonly and runstest-script-action):dotnet sonarscanner begin/endaccepts/d:sonar.tokenand readsSONAR_TOKENnatively. Taken from the issue's evidence, where an inline workflow settingenv: SONAR_TOKENpassed against the same project key, organisation and token minutes after this action failed.setup-dotnet@v6andsetup-java@v5behave as documented on the runner images. Assessed from release notes only.The real end-to-end proof is the next consuming build.
ploch-commonis inline and unaffected;ploch-commandlinehas replaced this action with an inline workflow (mrploch/ploch-commandline#17) and was deliberately not touched here.Breaking Changes
actions/setup-dotnet@v6andactions/setup-java@v5run on the Node 24 runtime and require a runner at v2.327.1 or newer. GitHub-hosted runners satisfy this automatically; any self-hosted runner must be updated.random-numberoutput is no longer declared. It always evaluated to an empty string and referenced a step that does not exist, so no working consumer can depend on it.No input names, defaults or required-ness changed, so existing
with:blocks continue to work untouched.Review round 1 (commit
bc2af89)Three threads were raised on
d56735a; all three have an on-thread reply and are resolved.dotnet-versiondescription wrongly impliedglobal.jsonis a fallbackactions/setup-dotnet, which therefore never falls back toglobal.json. Description reworded to say so. Declined the accompanying suggestions to make the input required (breaks every consumer at@main) and to add aglobal-json-filepassthrough (speculative new API surface).build-test-sonar.ps1runs the scanner anonymously whenSONAR_TOKENis unsetdotnet tool install --globalexits non-zero when the tool is already installed. A correct fix needs per-command$LASTEXITCODEhandling in a script that is currently dead code. Rolled into #2, which already asks whether these scaffolds should be updated or deleted.bc2af89itself was not independently re-reviewed: CodeRabbit reportedReview rate limitedand states it does not re-review already-reviewed commits, and CodeAnt did not re-trigger. A fresh review was explicitly requested and refused by the service. That commit is a documentation reword plus a four-line guard in an unwired script, both verified locally as described above.Related
