I believe you want to use FileLocator here, like here:

no, we need the name of the jar, not of any file inside. The proposed solution is basically a copy paste of org.eclipse.test.internal.AwtScreenshot.dumpAwtScreenshot(String). However i have not tested it and would like to just let it try on i-build

this did not help. it logged (no jar but wrong path!):
