Some test tasks fail to run when run in isolation

[bergerkiller]

When running either command after a clean (git) checkout (JDK 17):

./gradlew :cloud-annotations:testJava8
./gradlew :cloud-annotations:testJava11

The tests fail with an error, indicating the test classes were not (all) built prior to running the tests:

org.gradle.api.internal.tasks.testing.TestSuiteExecutionException: Could not execute test class 'cloud.commandframework.annotations.AnnotationParserTest$AliasedCommands'.

Running the rest of the build with -x these tests allows the tests to work again afterwards as by then the test sources are built. Its probably a configuration dependency issue for the tasks, but I dont know how to fix that myself.

I ran into this when trying to do a staged build of cloud because it used up too much memory building in one go, and the same issue occurred when just running: ./gradlew clean :cloud-core:build :cloud-bukkit:build :cloud-paper:build

The same issue appears prevalent with the testjava8/testjava11 of other tasks like building kotlin coroutines and fabric.

I can't reproduce this with ./gradlew clean :cloud-core:build and latest master

I also cannot replicate this, and we've seen no further reports of the issue.
