Eclipse NoSuchMethod exception; configuring build path <p>I have a maven project which actually builds as multiple java projects. Project B contains a class which is a child of a class sin Project A. When I try to run this class in a debugger I get a NoSuchMethod error when the method tries to call any functionality from it's parent.</p> <p>The Maven setup is designed to compile every single project and place it in the maven repository so other projects can find them (it has a sense of dependency so it builds pre-req projects firsts). This is all good for deployment, but I don't want to force people debugging in eclipse to do a maven install every time the start up their debugger. Instead I tried adding pre-req projects to the class path of the applicable projects (build path -> add class folder). This doesn't work. I <em>think</em> it's due to having both the maven repository and the class path in my build path? but the class folders should be parsed forced and the newer class folders should be parsed before the maven install right?</p> <p>How can I configure this to work without needing to re-do a maven install each time?</p>
