Spotless Gradle plugin 7.0.0: Eclipse / p2 download race condition

[breskeby]

I'm testing updating the elasticsearch build to use the Spotless Gradle plugin 7.0.0-BETA4.

In our CI we see multiple spotlessJava tasks in our build failing due to this error message:

Cannot fingerprint input property 'stepsInternalEquality': value 'com.diffplug.spotless.ConfigurationCacheHackList@a34eb6af' cannot be serialized.

It runs on Ubuntu 20.04.6

My changes are public available https://github.com/breskeby/elasticsearch/tree/update-spotless-gradle-plugin-700beta4

We don't run this in configuration cache mode.

This might be resolved in 7.0.0. If it's not, can you tell me what command to run to replicate the error? I cloned the repo but spotlessApply is working for me even with 7.0.0.BETA4.

[danielthegray]

It's not resolved, we are on Gradle 8.12 upgraded to version 7.0.0 and started having this problem intermittently, so it seems that there is some race condition involved in reproducing the bug. We have upgraded to 7.0.1 and continue to face the issue quite frequently (causing failed builds). We use a private mirror of the Eclipse P2 repo (that we had to set up as we were impacted by some removals of old versions by them), if that helps at all in reproducing it.

I have filed a bug for the root cause of this issue here equodev/equo-ide#181

In the meantime, if you have caching on the /home/jenkins/.m2/repository/dev/equo/p2-data/ directory, I would expect that these errors would go away once all of the jars and metadata are cached.

[danielthegray]

Sorry for not stating this more clearly, these builds run on single-use Jenkins node, so each Gradle build invocation is done "for the first time" on that machine, no caching is present. We've downgraded for now, but we'll keep our eyes open for a fix on the race condition issue. Thanks for your help!

This should be fixed in plugin-gradle 7.0.2

[bwaldvogel]

I still sometimes see the

Cannot fingerprint input property 'stepsInternalEquality': value 'com.diffplug.spotless.ConfigurationCacheHackList@52d095a9' cannot be serialized.

error, even after bumping to 7.0.2.

[nedtwigg]

Is it the same --stacktrace of

Caused by: java.nio.file.FileAlreadyExistsException: /home/jenkins/.m2/repository/dev/equo/p2-data/bundle-pool/https-eclipse-p2-mirror.com-p2-4.34-/com.sun.jna_5.15.0.v20240915-2000.jar
