Shouldn't benchmarks be compiled separately? Could you explain why modules need to depend on the engine's private benchmarks?

the error message without was:

> Task :engine:jar
> Task :modules:CoreAssets:compileJava NO-SOURCE
> Task :modules:BiomesAPI:compileJava FAILED

FAILURE: Build failed with an exception.

* What went wrong:
A problem was found with the configuration of task ':modules:BiomesAPI:compileJava' (type 'JavaCompile').
  - Gradle detected a problem with the following location: '/srv/http/repos/terasology/engine/build/classes'.
    
    Reason: Task ':modules:BiomesAPI:compileJava' uses this output of task ':engine:compileJmhJava' without declaring an explicit or implicit dependency. This can lead to incorrect results being produced, depending on what order the tasks are executed.
    
    Possible solutions:
      1. Declare task ':engine:compileJmhJava' as an input of ':modules:BiomesAPI:compileJava'.
      2. Declare an explicit dependency on ':engine:compileJmhJava' from ':modules:BiomesAPI:compileJava' using Task#dependsOn.
      3. Declare an explicit dependency on ':engine:compileJmhJava' from ':modules:BiomesAPI:compileJava' using Task#mustRunAfter.

thanks for the feedback on discord. to make the engine jar not contain the jmh files i added

    exclude("src/jmh")

which then allowed to compile it without all these undesired dependency spread out.

Unfortunately, this fails to run the tests succesfully at the moment:

This still does not compile, unfortunately:

@soloturn are you planning to take this up again?

@jdrueckert jdrueckert added the Status: Needs Author Input Requires more information by the author on the reported issue or provided changes label Apr 21, 2024
@soloturn
rename to build.gradle.kts
1966bb5 
* timestamp cannot be ignored easily with ignoreproperties, so leave
it as is, and remove the todo.

* move down writing the jar file, to assure version is specified in
 typehandlerlibrary e.g. which has it like project(:engine).version

* add jmh gradle plugin

running out of ideas how to fix this i asked in the gradle forums:
https://discuss.gradle.org/t/exclude-jmh-files-in-resulting-jar-jmh-plugin-bug-or-our-bug/48450

tried different notation now, removing the duplicate task. if you could test it again please with gradle jmh.
