Regression with Gradle's configuration cache in 0.9.15

[wilkinsona]

Describe the bug
In some circumstances, a Gradle build fails when run using --configuration-cache due to a Configuration instance that's captured by a lambda in NativeImpagePlugin. The same build works with 0.9.14.

To Reproduce
Sorry, I've yet to manage to boil things down into a minimal reproducer. Hopefully the configuration cache problem report (see below) will be sufficient to diagnose the problem.

Expected behavior
The Gradle plugin should work with --configuration-cache.

@wilkinsona would it be possible for you to try to build and test this branch?

[wilkinsona]

That was quick. Thank you, @melix. That's better as the configuration cache no longer reports a problem. Unfortunately, the build still fails:

./gradlew --configuration-cache generateResourcesConfigFile
Configuration cache is an incubating feature.
Calculating task graph as no configuration cache is available for tasks: generateResourcesConfigFile

0 problems were found storing the configuration cache.

Configuration cache entry discarded.

I don't see the failure with 0.9.14. It occurs with 0.9.15 and 0.9.16-SNAPSHOT.

nbt-configuration-cache-problem.zip contains a reproducer that should fail as above.

Thanks for the reproducer! 👀

It seems we're actually hitting a Gradle bug here :/ I'm trying to see if we can workaround.

[melix]

How critical is this for you? I'm afraid I'm hitting wall after wall, there seem to be bugs in Gradle I can't workaround :(

Happening when the cache is deserialized.

[wilkinsona]

Thanks for trying, @melix. It's not hugely critical. We have some users who care about the configuration cache but they're definitely a minority. I've disabled the failing test that alerted me to the problem so we're not blocked. Let's revisit this when there's more time to do so.

[shoaniki]

This isn't a showstopper by any means, but it is causing a certain amount of pain -- we've recently put some effort into fixing our build to support the configuration cache, and this is one of the few issues preventing us turning it on globally.

Just realised as I was typing this that #339 hasn't been merged yet – is it worth trying with that patch, or are the Gradle problems more deep-rooted than that?
