This repro contains a minimal example of a problem logged at gradle-dependency-analyze/gradle-dependency-analyze#201
We have an internal plugin where one of its tasks forces resolution of configurations during its processing. After updating to 1.6.0 with Gradle 6.9, I was seeing failures like the following on certain combinations of commands:
> Task :analyzeClassesDependencies FAILED
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':analyzeClassesDependencies'.
> Cannot change dependencies of dependency configuration ':apiHelper' after it has been resolved.
After some experimentation, I found that two tasks (forceConfigurationResolution being our custom task), available in the repro repo, will cause the error on >= 1.6.0 but don't on 1.5.3.
./gradlew forceConfigurationResolution analyzeClassesDependencies
I suspect that this is an unintended side-effect in the recent gradle-dependency-analyze since it worked before and I don't know why analyzing things would need to modify the dependency collections.
