Motivation

Ensure source-based :libs:* submodule projects are represented as concrete jar lib entries in Eclipse instead of empty src placeholders that require manual fixes.
Support mixed Java/Kotlin submodules by selecting the actual produced archive (shadowJar when present, otherwise jar) for the IDE classpath.
Produce deterministic, stable .classpath entries by copying the built jars into build/ide-libs and stripping transient hash suffixes.

Description

Added discovery of :libs:* project dependencies into a new sourcePluginProjects set and call evaluationDependsOn so subprojects are available when assembling IDE artifacts.
Prefer shadowJar and fall back to jar for each submodule, copy the produced archive (archiveFile) into build/ide-libs, and normalize filenames by removing the git-hash suffix.
Make eclipseClasspath depend on the copy tasks and expose the copied jars via an ideLibs configuration so Eclipse resolution can consume them.
Update .classpath post-processing to remove stale/unresolved src entries that start with /libs: and append deterministic lib entries for the copied jars (prevents empty module placeholders).

Testing

Ran ./gradlew eclipseClasspath in this environment, which failed early; the failure is due to Kotlin/Java toolchain parsing (java.lang.IllegalArgumentException: 25.0.1) and not the new script logic.
Ran ./gradlew eclipseClasspath --stacktrace which reproduced the same Kotlin/Java evaluation error, preventing runtime validation of the generated .classpath here.

Codex Task

### Motivation - Ensure source-based `:libs:*` submodule projects are represented as concrete jar `lib` entries in Eclipse instead of empty `src` placeholders that require manual fixes. - Support mixed Java/Kotlin submodules by selecting the actual produced archive (`shadowJar` when present, otherwise `jar`) for the IDE classpath. - Produce deterministic, stable `.classpath` entries by copying the built jars into `build/ide-libs` and stripping transient hash suffixes. ### Description - Added discovery of `:libs:*` project dependencies into a new `sourcePluginProjects` set and call `evaluationDependsOn` so subprojects are available when assembling IDE artifacts. - Prefer `shadowJar` and fall back to `jar` for each submodule, copy the produced archive (`archiveFile`) into `build/ide-libs`, and normalize filenames by removing the git-hash suffix. - Make `eclipseClasspath` depend on the copy tasks and expose the copied jars via an `ideLibs` configuration so Eclipse resolution can consume them. - Update `.classpath` post-processing to remove stale/unresolved `src` entries that start with `/libs:` and append deterministic `lib` entries for the copied jars (prevents empty module placeholders). ### Testing - Ran `./gradlew eclipseClasspath` in this environment, which failed early; the failure is due to Kotlin/Java toolchain parsing (`java.lang.IllegalArgumentException: 25.0.1`) and not the new script logic. - Ran `./gradlew eclipseClasspath --stacktrace` which reproduced the same Kotlin/Java evaluation error, preventing runtime validation of the generated `.classpath` here. ------ [Codex Task](https://chatgpt.com/codex/tasks/task_e_69aed969c30c832f8a6bfacf9538569d)
