While following the first cheat sheet under Creating an Eclipse plug-in, titled "Create a plug-in," a Java.lang.NullPointerException arose, and I'd like your help understanding the problem.|
The cheat sheet has five parts. I got through the first three fine. Those are Introduction, Configure PDE, and Create the plug-in.
The fourth one, Modify the plug-in, is where the error arose. That section says,
To modify your com.example.helloworld plug-in, perform the following steps:
- Select the "Extensions" tab.
- Expand the "org.eclipse.ui.actionSets" tree dialog under the "All Extensions" heading.
- Expand the "Sample Action Set" tree dialog.
- Select the "Sample Menu" entry.
This is where the NullPointerException arose. The message at the top of the Extensions tab says, "No schema found for the 'org.eclipse.ui.actionSets' extension point." What does this mean?
A screenshot is attached.
Here are my software details:
