Paul King commented on GROOVY-8775:
-----------------------------------
Thanks, yes I could replicate also with Maven 3.5.4. This is something we
haven't fixed for JDK9+ yet but there is a workaround.
Details: we create the classpath for javac based on all the jars that the
groovyc classloader knows about. That way it covers jars that might have been
@Grab'd and/or potentially added via a custom compilation configuration script.
We do it by walking up the classloader hierarchy and extract jars from
URLClassloaders. This has changed in JDK9 where URLClassloaders aren't returned
any more and for a full solution we'd need to potentially traverse all modules
on the module path as well as the classpath. We are still working on that.
In the meantime, you can provide an explicit classpath setting to javac and we
don't do the above process:
{code}
...
<javac encoding="utf-8" debug="true">
<compilerarg value="-JclasspathOverride=${toString:compile-lib}"/>
</javac>
...
{code}
