Description of the bug

After setting up the template project and running the genIntellijRuns task, when trying to runClient I get this error:

Exception in thread "main" java.lang.module.ResolutionException: Module org.antlr.antlr4.runtime reads more than one module named cpw.mods.securejarhandler
	at java.base/java.lang.module.Resolver.resolveFail(Resolver.java:901)
	at java.base/java.lang.module.Resolver.checkExportSuppliers(Resolver.java:722)

I have tried rerunning the gen task, remaking the project, switching the forge version, and removing the .gradle file where all the libraries are stored, but nothing has fixed this issue. This would seem to be a recent issue as older mods I started using this plugin don't run into the same issue. I should also note that the module that reads more than one of the cpw.mods.securejarhandler modules seems to change pretty regularly. No idea what is causing this or how I'm even supposed to go about fixing/debugging it.

Try it with forge_version=47.2.0 in your build.gradle or just try to create a new project with forge version 47.2.0 may work. I met the same issue with you and solve it like what I said.
