Re: [eclipse-dev] Using refactoring code outside of eclipse

You can't get an NPE on said line because
that's a call to a static method.

Such questions should be posted to the
newsgroups (jdt in this case).
From http://eclipse.org/mail/index.html:
Technical questions and discussions about using eclipse
and eclipse-based tools, and developing plug-in tools should be posted
to the newsgroups.
Mailing lists at eclipse.org are intended for use by developers actually
working on or otherwise contributing to day-to-day development.

Subject	[eclipse-dev] Using refactoring code outside of eclipse

Hi, 

I am trying to get this code working: 


import junit.framework.TestCase; 
import org.eclipse.jdt.testplugin.JavaProjectHelper;
import org.eclipse.jdt.internal.ui.JavaPlugin; 
import org.eclipse.jdt.core.IPackageFragmentRoot; 
import org.eclipse.jdt.core.IJavaProject; 
import org.eclipse.jdt.core.IPackageFragment; 
import org.eclipse.jdt.core.ICompilationUnit; 

public class SpikeTestCase extends TestCase { 
    private IJavaProject javaTestProject;
    private IPackageFragmentRoot root; 
    private static final String CONTAINER = "";
    private IPackageFragment packageP; 

    protected void setUp() throws Exception {
                super.setUp();
                JavaProjectHelper.setAutoBuilding(false);
                if (JavaPlugin.getActivePage()
!= null) 
                    
   JavaPlugin.getActivePage().close(); 
                javaTestProject=
JavaProjectHelper.createJavaProject("TestProject"+System.currentTimeMillis(),
"bin"); 
                JavaProjectHelper.addRTJar(javaTestProject);
                root= JavaProjectHelper.addSourceContainer(javaTestProject,
CONTAINER); 
                packageP= root.createPackageFragment("p",
true, null); 
        } 

    public void testSimpleRefactoring() throws Exception {
        ICompilationUnit cu = createCUfromTestFile(getPackageP(),
"A"); 
    } 

    protected ICompilationUnit createCUfromTestFile(IPackageFragment
pack, String contents) throws Exception { 
                return createCU(pack,
"mike" + ".java", contents); 
        } 

    public static ICompilationUnit createCU(IPackageFragment
pack, String name, String contents) throws Exception {
                if (pack.getCompilationUnit(name).exists())
                    
   return pack.getCompilationUnit(name);
                ICompilationUnit
cu= pack.createCompilationUnit(name, contents, true, null);
                cu.save(null, true);
                return cu;
        } 

    protected IPackageFragment getPackageP() {
            return packageP;
        } 

} 

I get a NullPointerException on the second line of the setUp method, the
line that reads "JavaProjectHelper.setAutoBuilding(false);"

Does anybody have any idea what I need to do to get this to work?

Thanks, 
Mike
