Exception java.nio.file.FileAlreadyExistsException: instrumentCode/classpath.index

[jansorg]

I updated to gradle-intellij 1.6.0.
The first build worked fine, but further executions of Gradle fail with FileAlreadyExistsException. I'm using a multi-module project setup with several intellij-enabled Gradle modules. Please let me know if you need anything else to debug this.

 ./gradlew build -x test
> Task :instrumentCode FAILED

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':instrumentCode'.
> java.nio.file.FileAlreadyExistsException: /home/user/product/build/tmp/instrumentCode/classpath.index

Thanks, Joachim! I didn't run into such a problem so far. Could you please provide a minimal reproducible example?

[jansorg]

Unfortunately I don't have the time at the moment to prepare that, but I hope to provide one at some point. Hopefully another project with a simpler build structure will run into it before ;)

Faced this thing with IdeaVim plugin. I got it when I started a test twice, but can't reproduce it anymore at the moment.

[Benjamin-Dobell]

Sorry, I also don't have a straight-forward reproduction, however I thought I ought to point out that deleting build/tmp/instrumentCode/classpath.index file is not actually enough to resolve the problem. Same goes for build/tmp/.

I'm having to wipe out the entire build/ directory between test reruns.

I saw this same problem after upgrading to 1.6.0: https://github.com/intellij-dlanguage/intellij-dlanguage/runs/6666318499?check_suite_focus=true

not sure it if makes a difference but intellij-dlanguage is a multi-module project

@SingingBush In the linked build you get:

e: /home/runner/.gradle/caches/modules-2/files-2.1/com.jetbrains.intellij.idea/ideaIC/LATEST-EAP-SNAPSHOT/b271897f6f74a7e75a4394bd2c034d0c608c6da4/ideaIC-LATEST-EAP-SNAPSHOT/lib/3rd-party-rt.jar!/META-INF/kotlinx-datetime.kotlin_module: Module was compiled with an incompatible version of Kotlin. The binary version of its metadata is 1.7.1, expected version is 1.5.1.

Do you have any build that emits the FileAlreadyExistsException?

[SingingBush]

I just clicked that link to check and it scrolls down to the section that I pasted in the code block which has the line:

> java.nio.file.FileAlreadyExistsException: /home/runner/work/intellij-dlanguage/intellij-dlanguage/build/tmp/instrumentCode/classpath.index

[Konafets]

I faced the same issue. My workaround is to delete build/classes folder.

[dave-griffiths]

I saw it too so backed off to 1.5.3 for now.
