SBT package produces empty JAR after enhancing compiled classes

I am an author of a SBT plugin: https://github.com/atais/sbt-eclipselink-static-weave

It's purpose is to enhance compiled classes using provided StaticWeaveProcessor.

To achieve this step I have overriden the compile step with:

override def projectSettings: Seq[Def.Setting[_]] = Seq(
 ... 
 // https://www.scala-sbt.org/1.0/docs/Howto-Dynamic-Task.html#build.sbt+v2
 compile in Compile := Def.taskDyn 
 val c = (compile in Compile).value
 Def.task 
 (copyResources in Compile).value // we need to copy META-INF folder first, https://github.com/sbt/sbt/issues/3934
 weaveTask.value
 c
 
 .value
 )

Problem

Projects using this plugin compile properly, but they might produce an empty jar, during package or publish IF the compiled sources are not available beforehand.

You might want to check my pull-request where I have prepared a test project with test scenario.
https://github.com/atais/sbt-eclipselink-static-weave/pull/2

Details

I have tried printing all the settings and mappings, but they seem fine.

However, I have found, that Package.Configuration step is using cacheStoreFactory: CacheStoreFactory which I think is my problem.

during the function makeJar(sources.toSeq, jar.file, manifest, log) there is a log.debug(sourcesDebugString(sources)) which gives empty result on first run:

but properly lists files on the second:

SBT is not restarted between this runs. It's just second time I call package.

How could I produce proper jar on first run?

I am afraid I miss the question. What do you expect to achieve? You want the jar not to be empty? Or you want SBT restarted?
