java.lang.NullPointerException when I try to open a gradle file in my home folder #8
Description
Hi all,
the Nodeclipse gradle editor works fine when opening gradle files in my projects.
However, in this instance I am trying to open a build.gradle file in my home folder, not in an eclipse workspace.
When I try to open the file, this error happens, and the file does not open:
Problems occurred when invoking code from plug-in: "org.eclipse.ui.workbench".
