Writing JAR from plug-in (not from File menu) [message #1185045]

I'm writing a plug-in for Eclipse Standard/SDK Kepler to give diagnostic feedback to undergraduate student programmers as they work on their programming assignments. The student can run my plug-in as often as he wishes to see if his code triggers any messages about poor programming practices he might want to change. Each time the student invokes the plug-in, I need to save a JAR that includes all the .java files in the student's project as well as a text file containing the diagnostic feedback produced by the plug-in. I know the student can create a JAR using the File->Export->Java->JAR file option in Eclipse, but I want to create the JAR behind the scenes without asking the student to do anything more than choose a menu item to run the plug-in. I want to save the JAR to the directory that already holds the student's source files. I've been plowing through the documentation on Resources in the Platform Plug-in Developer Guide, so far without enlightenment. I would greatly appreciate any pointers you can offer.

Hannah,

Plug-in Spy can be very useful for finding how existing things in
Eclipse are implemented. E.g., you could open the export to archive
wizard and hit Alt-Shift-F1 to see which class implements that dialog.
Then you can look into how that source code is implemented and reuse the
ideas.

Thank you for the suggestion. I also discovered after I posted my question that there is a section about writing a JAR file in the JDT Plug-in Developer Guide, under JDT UI. I guess I did not use the perfect search terms when I first looked for how to save a JAR file. Hannah
