<modulepath/> option doesn't work for multi-module project

[gunnarmorling]

In ExecMavenMojo, it tries to create the file for the module path always under target/modulepath. This doesn't work if invoked from the root of a multi-module build for one of the modules (it'd have to be %mymodule%/target/modulepath then), and also fails if the user has configured another directory than target as their build directory.

I'll send a PR in a bit.

PR is here: #99

Any word on this? I just stumbled across this in my project while migrating to jdk11/jigsaw. Calling from the module, builds work fine, calling from the parent, builds fail as described.

Is there a viable workaround (other than building the module on its own)?

Can you create an integration-test for this, just to be sure #99 is all you need.
