Description
NullPointerException caused by Gradle STS plugin when switching away from a Gradle launch configuration in the "External Tools Configurations" view.
Steps to reproduce:
- Create a minimal Gradle project that contains a launch configuration and import into Eclipse
- Open External tool configs dialog
- In Eclipse, open the "External Tools Configurations" window and click on the "Gradle Build" node in the tree view to expand it
- Select an arbitrary child of the "Gradle Build" node
- Select a different node outside the "Gradle build" node (e.g. "Program", or "API Use Report")
Eclipse shows an exception and freezes. The window cannot be closed anymore and Eclipse will not close until killed.
The workspace log (<workspace_dir>/.metadata/.log" ) shows the exception stacktrace
