Ecliplse Plugin Development using JPMS [message #1847267]

Hello,

I'm developing an eclipse plug-in inside Eclipse PDE with Java 9+. I need to use some jar-s dependencies which are packed as modules. Currently I'm able to run the plugin from PDE only by passing --module-path and --add-modules arguments in run configuration inside PDE. Exporting the plug-in and installing it in eclipse will work only by changing eclipse.ini file where I pass the same args like before. So, my question is: Is it possible to export the plug-in with module dependencies, without editing the eclipse.ini file afterwards?... In plugin.xml I don't see anything related to modules. And extra question: Is there a way to load dynamically the modules in plug-in?

Thanks!

No, that is not possible because it is a java runtime requirement. You can alter the eclipse.ini by supplying a p2.inf file.
It is kind of magical and poorly documented but this should get you going:

# Workaround for bug 572210 (<https://bugs.eclipse.org/bugs/show_bug.cgi?id=572210>):
# in "eclipse.ini" add the VM argument "--illegal-access=permit"
instructions.configure=org.eclipse.equinox.p2.touchpoint.eclipse.addJvmArg(jvmArg:--illegal-access=permit)
instructions.unconfigure=org.eclipse.equinox.p2.touchpoint.eclipse.removeJvmArg(jvmArg:--illegal-access=permit)
