Can't pass --module-path argument to the compiler.

[DanielChicot]

In order to build a java 9/10 module based aspect j project with maven I need to add aspectjrt.jar to the module path. The ajc compiler has the --module-path option e.g.:

ajc --module-path c:/opt/aspectj1.9/lib/aspectjrt.jar ...

but I can't seem to get the aspectj-maven-plugin to pass this through to the compiler.

aspectj-maven compiler version 1.11.
aspectj version 1.9.1

Note that I can get around this with the ASPECTJ_OPTS environment variable, e.g.

$ export ASPECTJ_OPTS="--module-path c:/opt/aspectj1.9/lib/aspectjrt.jar"
$ mvn aspectj:compile

Is there any news on this? It kinda seems like this project is stale (dead?). How come?

I opened a PR with fix toallow to pass arbitrary command line arg to the compiler.
Please merge ASAP

A couple of years ago, my PR #100 was not merged, but as a maintainer of both AspectJ and https://github.com/dev-aspectj/aspectj-maven-plugin, I added basic support for --module-path back then. Look for option javaModules there. If you have any problems, please open an issue there.
