> Task :generateEffectiveLombokConfig
Execution optimizations have been disabled for task ':generateEffectiveLombokConfig' to ensure correctness due to the following reasons:
  - Gradle detected a problem with the following location: '/home/sysc4ll3r/burpsuite-stuff/awesome-external-extensions/LoggerPlusPlus/build/generated/javacc'. Reason: Task ':generateEffectiveLombokConfig' uses this output of task ':compileJavacc' 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/7.5.1/userguide/validation_problems.html#implicit_dependency for more details about this problem.
  - Gradle detected a problem with the following location: '/home/sysc4ll3r/burpsuite-stuff/awesome-external-extensions/LoggerPlusPlus/build/generated/jjtree'. Reason: Task ':generateEffectiveLombokConfig' uses this output of task ':compileJjtree' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
