Hello !

I am having problems with this code:

------------------------------------------------------------ --
public class TesteJDT08 {

public static void main(String[] args) {

AST ast = new AST(new TreeMap());

IWorkspace workspace = ResourcesPlugin.getWorkspace();
System.out.println("\n After IWorkspace...");

IProject myProject = workspace.getRoot().getProject("TesteJDT08");
System.out.println("\n After IProject..."+myProject.getName());

}
}
------------------------------------------------------------ --
Output:
After IWorkspace...
java.lang.NullPointerException
at testejdt08.TesteJDT08.main(TesteJDT08.java:28)
Exception in thread "main"
------------------------------------------------------------ --
What is happening ?

What do I have to do?

Thanks

If you are running in a main you don't have a workspace. Workspaces only
exist while running in an eclipse environment. Since you don't have a
workspace it is returned as a null.

Hello,

yes. You can use the Plugin-Wizard with File->New
Project->Plugin-Development->Plugin-Project and then selecting Default
Plugin-Structure to create a minimal plugin.
