Assuming Penrose Studio is installed in PENROSE_STUDIO_HOME, copy your jar files into PENROSE_STUDIO_HOME\plugins\org.safehaus.penrose_x.x.x\lib.

Then go to PENROSE_STUDIO_HOME\plugins\org.safehaus.penrose_x.x.x\META-INF, edit the MANIFEST.MF, add your jar files into Bundle-ClassPath:

Bundle-ClassPath: lib/antlr-2.7.2.jar,
 ...
 lib/zql.jar,
 lib/<your jar file>

Note: if you add the new line at the bottom like above, make sure you add a comma at the end of the previous line.

Then go to PENROSE_STUDIO_HOME\configuration, remove the following directories:

org.eclipse.core.runtime
org.eclipse.osgi
org.eclipse.update

Finally, restart Penrose Studio.
