I configured my libraries to work and can generare a jar file manually for my project. The only way I can get the project to "run" though is to set up the jar and add my own genmerated jar as a required library for the project and then rebuild the jar before doing a run. If I do not haver the jar file, I get a class can not be found error. My assumption is that the run process should run on the class file in the output directory so it should not require the jar. Thoughts? Back to top Bill Joy Guest Posted: Mon Jan 22, 2007 8:26 pm    Post subject: Re: 2007 build woes Is that error really what you are getting? You should be getting an error about a build not being able to be initiated until a problem is fixed. With the Eclipse build system, everything on the project classpath has to exist before a build will be performed. Every jar must exist, every directory must exist. (You also cannot have the same jar being referenced twice on the project classpath.)

I am trying to run from the working directory of ${workspace_loc:my_project/classes} If I include my own jar file in the classpath, it runs fine. If I remove my jar from the classpath, I get a java.lang.NoClassDefFoundError (Exception in thread "main") for my class that I need to launch. It is my assumption that I sould not need my jar, it should run from the classes area right?

Are you creating a Run/Debug configuration for a Java Application and is the Search button seeing your main class? You should also be able to right-click on your main class in the Package Explorer and use the Run As or Debug As menu.

I created the run action but selecting "run..." menu item from the run menu. then I defined the following: main --> set main class and project name args --> set the working dir to my classes dir jre --> changed nothing classpath --> added my required libraries source --> set the source to my src dir env --> changed nothing common --> changed nothing If the classpath has the assembled jar (i.e. the output of this project) it works If the classpath does not have the jar, it gives a NoClassDefFoundError error "selecing run as application" when right clicking the launch class in the explorer gives the same result as the run menu, it succeeds with the jar and fails without it.

Not sure why you are modifying it -- I have never had to change the defaults for the classpath or source in a run configuration.
