对于未来的读者，
这是正确的答案：

但是我今天找到并解决了这个问题。我已经安装了Java 6和7. eclipse已经使用了Java 6。

对于其他人来说，有同样的问题：去设置应用程序> Java并转到Java -标签。以下是所有已安装的Java版本。更改版本的优先级，否则卸载或禁用旧版本。

I'm trying to use robovm on Eclipse. I have installed the robovm plugin.

But when I create a RoboVM eclipse project, Eclipse gives me an exception:

The selected wizard could not be started.
Plug-in org.robovm.eclipse.ui was unable to load class org.robovm.eclipse.internal.NewCocoaTouchProjectWizard.
An error occurred while automatically activating bundle org.robovm.eclipse.ui (244).

I get a similar message when I try to go to "Settings" > "RoboVM":

Unable to create the selected preference page.
An error occurred while automatically activating bundle org.robovm.eclipse.ui (244).

Can anyone can help me?

For future readers, Here is the right answer:

But i've found and solved the Problem today. I had installed Java 6 AND 7. eclipse had use Java 6.

For other peoples there have the same Problem: Go to the Settings App > Java and go to the Java-Tab. Here are all installed Java versions listed. Change the priority for the version otherwise deinstall or disable older Versions.
