Rely on `product-info.json` when building a classpath for tasks

[hsz]

With IJ 241.9959.31, plugin fails to load all necessary classes:

Execution failed for task ':plugin:core:generatePerl5Parser'.

This is because some classes were moved to a new opentelemetry.jar library, which is not listed in requiredLibs:

gradle-grammar-kit-plugin/src/main/kotlin/org/jetbrains/grammarkit/GrammarKitPlugin.kt

Lines 50 to 58 in 951065f

	val requiredLibs = listOf(
	"app", "lib", "jdom", "trove4j", "junit", "guava", "asm-all", "automaton", "platform-api", "platform-impl",
	"util", "util_rt", "annotations", "picocontainer", "extensions", "idea", "openapi", "grammar-kit",
	"platform-util-ui", "platform-concurrency", "intellij-deps-fastutil",
	// CLion unlike IDEA contains `MockProjectEx` in `testFramework.jar` instead of `idea.jar`
	// so this jar should be in `requiredLibs` list to avoid `NoClassDefFoundError` exception
	// while parser generation with CLion distribution
	"testFramework", "3rd-party",
	)

Use the data from the product-info.json file delivered with IJ dependency to avoid such problems.
The missing jar is present in:

launch[].bootClassPathJarNames, so it'll be necessary to discover the proper OS and architecture, like it's done in IntelliJ Platform Gradle Plugin 2.0

As a workaround, please add to the Gradle build file:

tasks {
    withType<GenerateParserTask> {
        classpath(setupDependencies.flatMap { it.idea.map { idea -> idea.classes.resolve("lib/opentelemetry.jar") } })
    }
}

For clarity... where is setupDependencies supposed to come from in the above workaround? 🤔 I'm using org.jetbrains.grammarkit:2022.3.2.1, trying to build against 241.10840.26-EAP-SNAPSHOT.

* Where:
Build file '/Users/pawel_lipski/git-machete-intellij-plugin/frontend/file/build.gradle.kts' line: 43

* What went wrong:
Script compilation errors:

  Line 43:     classpath(this.setupDependencies.flatMap { it.idea.map { idea -> idea.classes.resolve("lib/opentelemetry.jar") } })
                              ^ Unresolved reference: setupDependencies

  Line 43:     classpath(this.setupDependencies.flatMap { it.idea.map { idea -> idea.classes.resolve("lib/opentelemetry.jar") } })
                                                          ^ Unresolved reference: it

  Line 43:     classpath(this.setupDependencies.flatMap { it.idea.map { idea -> idea.classes.resolve("lib/opentelemetry.jar") } })
                                                                        ^ Cannot infer a type for this parameter. Please specify it explicitly.

3 errors

[PawelLipski]

For anybody having the same error: just use:

tasks {
  withType<GenerateParserTask> {
    val setupDependenciesTask = findByPath(":setupDependencies") as SetupDependenciesTask
    classpath(setupDependenciesTask.idea.map { idea -> idea.classes.resolve("lib/opentelemetry.jar") })
  }
}

The suggested solution is not possible to implement ATM.
The hotfix with hardcoded opentelemetry entry was just published as 2022.3.2.2.
