问题
I have developed an RCP plug-in (not standalone), and a Java Project with library code that the plug-in needs to call.
I have configured the Java Project in the same workspace. The plug-in has a project dependency on the Java Project.
The code compiles (the plug-in does some stuff with the Java Project / library code).
When I run the plug-in, I get a ClassNotFoundException:
java.lang.ClassNotFoundException: com.mycode.ArgSet
at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:494)
Anyone know how to configure the plug-in properly?
回答1:
Convert your library project to a plug-in project (right-click -> Configure -> Convert to Plug-in Project) and add it to the dependencies of your plug-in project (manifest editor, Dependencies tab).
回答2:
You can also generate a JAR of your libray Project and add this jar to your plugin-project. That's the way we do it (but thats not that automatically, you have to export manualy every time you change the library-project.
The other bad with this jar-export is: when using another libraries (i.E. AXIS2 for Webservice,...) this Libraries must have also been added to the plugin project.
