On Windows, there is a limit for command line length. When having much dependencies, one hits this limit. A workaround is to convert the --module-path argument into a file (which is a Command-Line Argument File). This is done by the Classpath to File Gradle Plugin.

The gradle team also thought of solutions, but there is no progress (see gradle/gradle#1989).

The "simple" workaround at gradle/gradle#1989 (comment) does not work: The jar files are not found by gradle-modules-plugin.

I wonder whether org.javamodularity.moduleplugin.tasks.RunTaskMutator#updateJavaExecTask can be patched to shorten the command line? I would propose to use "Solution 1" of gradle/gradle#10114 (comment).
