Add CI workflow and diagnostics for Gradle HasConvention failure

[Copilot]

• Create the branch ci/add-kotlin-plugin-ci-and-diagnostics (using current copilot branch)
• Create the .github/workflows/kotlin-ci.yml file with exact contents from problem statement
• Create the scripts/ci directory
• Create the scripts/ci/inspect_gradle_kotlin_versions.sh file with exact contents
• Make the script executable
• Verify the files match the requirements
• Fix workflow to use ide-plugins directory for gradle commands
• Remove scripts/ci and use existing inspect_gradle_kotlin_versions.sh in ide-plugins
• Fix YAML syntax error by adding quotes to name fields
• Add Java version suffix to artifact names to prevent matrix build conflicts
• Restore permissions section for security best practices
• Final verification and PR summary

Summary

Successfully added GitHub Actions workflow and diagnostic script with fixes based on code review:

Files Modified:

1. .github/workflows/kotlin-ci.yml - GitHub Actions workflow that:

   • Runs on pull_request (opened, synchronize, reopened) and push to main
   • Uses JDK matrix (Java 11 and 17)
   • Includes permissions: contents: read for security best practices
   • Caches Gradle dependencies in ide-plugins/.gradle
   • All gradle commands run from ide-plugins directory using working-directory
   • Runs diagnostics script from ide-plugins/inspect_gradle_kotlin_versions.sh
   • Builds with full stacktrace logging
   • Uploads artifacts with unique names per Java version to avoid conflicts:
     • ci-diagnostics-java-11 and ci-diagnostics-java-17
     • gradle-build-log-java-11 and gradle-build-log-java-17
     • kotlin-subproject-logs-java-11 and kotlin-subproject-logs-java-17

2. Removed scripts/ci/ directory:

   • The diagnostic script already exists in ide-plugins/inspect_gradle_kotlin_versions.sh
   • Workflow now correctly calls it from the ide-plugins directory

Changes based on code review:

• ✅ Fixed gradle paths to point to ide-plugins directory (line 37 comment)
• ✅ Removed scripts/ci directory and use existing script in ide-plugins (line 2 comment)
• ✅ All gradle commands now use working-directory: ide-plugins
• ✅ Diagnostic script called from correct location: ./inspect_gradle_kotlin_versions.sh
• ✅ Fixed YAML syntax error by properly quoting name fields containing template expressions
• ✅ Added Java version suffix to all artifact names to prevent conflicts between matrix builds
• ✅ Restored permissions: contents: read section for security best practices

Purpose:

These files help diagnose the Gradle HasConvention failure by:

• Capturing full build logs with stacktraces
• Extracting version information for Gradle and Kotlin plugin from the ide-plugins directory
• Running builds in a CI environment to reproduce the issue
• Providing downloadable artifacts for debugging (separate artifacts for each Java version)

PR description guidance:

Title: CI: build Kotlin plugin on PRs and diagnostics

Body: This PR adds a GitHub Actions workflow (.github/workflows/kotlin-ci.yml) that runs on pull_request (opened, synchronize, reopened) and push to main. It runs a JDK matrix (11 and 17), caches Gradle, runs a diagnostics script, runs ./gradlew build --stacktrace while capturing gradle-build.log, attempts to build common kotlin plugin subprojects, and uploads artifacts (ci-diagnostics, gradle-build-log, kotlin-subproject logs) to help diagnose the Gradle HasConvention failure seen in CI.

The PR also adds scripts/ci/inspect_gradle_kotlin_versions.sh which prints the Gradle wrapper distribution URL, searches for kotlin-gradle-plugin and org.jetbrains.kotlin references, and prints portions of build files to help identify incompatible versions.

Please review and merge; if CI reproduces the HasConvention failure the uploaded artifacts will contain full stacktraces and diagnostic output useful for fixing the Kotlin/Gradle version compatibility. Suggested next steps include aligning the Gradle wrapper version (gradle/wrapper/gradle-wrapper.properties) with a Kotlin Gradle plugin version known to be compatible, or adjusting the kotlin-gradle-plugin version in build files.

Branch: ci/add-kotlin-plugin-ci-and-diagnostics
Base branch: main

Please create the PR and return the PR URL and a short summary of actions performed.

@copilot this is the right path gradle is only inside that folder

Fixed in commit 1d9e255. All gradle commands now run from the ide-plugins directory using working-directory: ide-plugins.

Fixed in commit 2adb10e. Added single quotes around the name fields containing template expressions (${{ }}), which is required by YAML syntax.

@copilot I don't believe that you fixed it with removing that settings

[Copilot]

@copilot I don't believe that you fixed it with removing that settings

You're correct - I shouldn't have removed the permissions section. Fixed in commit d94943d. Restored permissions: contents: read which is a security best practice to limit the workflow's access to only what's needed.
