Warning since Gradle 7.x: Execution optimizations have been disabled for task ':processResources'

[bwaldvogel]

I’m using the XJC Gradle plugin (version 2.0.0) with the configuration

sourceSets {
    main {
        xjcCatalog.srcDir("my/package")
        xjcTargetPackage = "my.package"
    }
}

xjc {
    extension = true
}

After upgrading Gradle from 6.x to 7.x, I get the following new warning when assembling the project via ./gradlew assemble:

> Task :processResources
Execution optimizations have been disabled for task ':processResources' to ensure correctness due to the following reasons:
  - Gradle detected a problem with the following location: 'my-project/build/generated/resources'. Reason: Task ':processResources' uses this output of task ':xjcGenerate' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed. Please refer to https://docs.gradle.org/7.3/userguide/validation_problems.html#implicit_dependency for more details about this problem.
  - Gradle detected a problem with the following location: 'my-project/build/generated/resources/xjc/main'. Reason: Task ':processResources' uses this output of task ':xjcGenerate' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed. Please refer to https://docs.gradle.org/7.3/userguide/validation_problems.html#implicit_dependency for more details about this problem.

To hide the warning, I declared an explicit task dependency as a temporary workaround:

processResources.dependsOn xjcGenerate, xjcGenerateTest

same problem here, even worse: when having multiple xjc configurations, gradle complains about circular dependencies among them. the workaround given above unfortunately does not work for me.
