The developer notes on how to compile and debug Jmeter with Eclipse 1 and 2 are very difficult to follow and outdated. If you are interested in modifying Jmeter using Eclipse 3.2 Callisto you can follow the following procedure:

tags/v2_2. Right-click on it and select Checkout. Use then New Project Wizard.eclipse.classpath to .classpath. Delete the eclipse generated .classpath first.<Project name>/lib/ext.images/*, etc. in the Build Path→Sourcelib/ext folder and see if eclipse is compiling ok. If not check the Problems view to see if the project was not built since its build path is incomplete. Probably your are missing some library. Commons-logging has to be change from commons-logging-1.1 to commons-logging. If it complains about javax.mail.MessagingException then you have to add mail.jar to the build pathAt startup JMeter search for classes deriving from JMeterGUIComponent or TestBean. Now the context menus are populated with items.
