Execution optimizations have been disabled for task ':minecord-api:genSources' to ensure correctness due to the following reasons:
  - Gradle detected a problem with the following location: 'C:\Users\username\.gradle\caches\fabric-loom\1.17.1-mapped-net.fabricmc.yarn-1.17.1+build.25-v2\minecraft-1.17.1-unpicked-net.fabricmc.yarn-1.17.1+build.25-v2.jar'. Reason: Task ':minecord-api:genSources' uses this output of task ':unpickJar' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed. Please refer to https://docs.gradle.org/7.1.1/userguide/validation_problems.html#implicit_dependency for more details about this problem.

This happens because Gradle thinks (incorrectly, really) that subprojects' genSources tasks cross-depend on unpickJar from other projects since they touch the same file.

In your case (assuming you have the same mappings/AWs for each subproject), you can fix this by only running genSources in just the root project or one subproject.

[axieum]

I mentioned in the issue that I ran genSources only from the root project, it just cascades to all subprojects.

[Juuxel]

No, if you do gradlew genSources it does it in all projects where it's found. gradlew :genSources with a colon would be the root project's. (Tasks won't cascade unless you don't specify the project path like : or :mySubproj:)

unpickJar task was removed, likely fixing this issue.
