Re: [atf-dev] NullPointerException when using ATF
|
Marcus-- There have been many changes to ATF in this release that may cause issues with projects created before the new release is installed. A workaround on your end is to copy the files out of your project into a temp directory at the OS level, delete the original project and create a new one. Then re-import the files into the new project.
Javier--
I'm not sure precisely what is causing Marcus' error. My guess is that getToolkitFolders() is causing the NPE or else its not returning any folders (causing an NPE further down). Has the way ATF keeps track of runtime folders changed? The (quick) fix below should work for now.
(org.eclipse.atf.compatibility.jsdt.ATFClasspathContainer.getClasspathEntries():140) :
============================================
public IClasspathEntry[] getClasspathEntries()
{
IFolder[] toolkitFolders = getToolkitFolders();
....
=============================================
goes to :
=============================================
public IClasspathEntry[] getClasspathEntries()
{
IFolder[] toolkitFolders;
try {
toolkitFolders = getToolkitFolders();
} catch (Exception ex) {
toolkitFolders = new IFolder[0];
}
...
==============================================

With ATF 0.2.3M3 I get an error pop-up saying a NullPointerException
occurred when initializing the _javascript_ tooling. This happens when I
open the Web Development perspective, and also when I try to open an
existing web project. (As a result, the Project Explorer doesn't show
the files in my web project - I cannot expand the project directory
although it isn't empty.)
The log is attached.
Regards,
Marcus
