ModuleMainClass attribute via module-info.java

[Jendrik Johannes]

Hi,

Just wanted to mention for anyone ending up here as it is related:
In Gradle's Java Module support (since Gradle 6.5) we faced the same issue
as it fits the input/output model of Gradle tasks better if the
*compileJava* task does all the class file creation/modification. So in
Gradle it is possible to set the ModuleMainClass attribute on the
compileJava task. It is implemented by rewriting the module-info.class with
ASM right after it was created by the Java compiler.

https://docs.gradle.org/current/userguide/application_plugin.html#sec:application_modular

Cheers
Jendrik
