Question

I found a nice todo-tool that is based on eclipse-rcp and xtext (Sebastian Benz – Eclipse-Task-Editor). I cloned the git repository an exported the product. Unfortunately, I’m getting following exception as starting the eclipse product:

Caused by: java.lang.ClassNotFoundException: org.eclipse.swt.SWTError
    at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:513)
    at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:429)
    at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:417)
    at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:107)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
    ... 43 more

The entire stack trace can be found (here). I found a guy having the same exception caused by some wrong parameters. I removed all of them but the exception is still present. Do you have a clue what could cause the issue? Thank you!

I use Eclipse Indigo Service Release 1 on Gnome/Linux with the following java version:

java version "1.6.0_26"
Java(TM) SE Runtime Environment (build 1.6.0_26-b03)
Java HotSpot(TM) 64-Bit Server VM (build 20.1-b02, mixed mode)

Maybe , the application not found the right swt lib in your plugin folder. you need a jar named “org.eclipse.swt.gtk.linux.x86_64_xxxx.jar”. you can check it.
