When using JMH Gradle Plugin 0.6.5 with Gradle 7.2 and configuration on demand, Gradle will complain about a missing dependency of :compileJmhJava to :compileTestJava unless jmh.includeTests has been explicitly set to false or the task dependency has been explicitly declared.
Gradle detected a problem with the following location: '/path/to/gradle-jmh-config-cache/build/classes/java/test'. Reason: Task ':compileJmhJava' uses this output of task ':compileTestJava' 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/7.2/userguide/validation_problems.html#implicit_dependency for more details about this problem. This behaviour has been deprecated and is scheduled to be removed in Gradle 8.0. Execution optimizations are disabled to ensure correctness. See https://docs.gradle.org/7.2/userguide/more_about_tasks.html#sec:up_to_date_checks for more details.
Expected behavior:
When jmh.includeTests is true (default), the JMH Gradle Plugin should add the task dependency itself.
