Description felix.ziesel

2010-11-01 09:39:08 EDT

When using <Select-Project-Context-Menu>->Properties->AspectJ Build->Inpath->Add Library->Plugin Dependencies and adding an non-default output folder at the bottom. Than pressing OK. I get the following Exception in the dialog:

java.lang.NullPointerException
at org.eclipse.ajdt.internal.core.ajde.CoreOutputLocationManager.workspacePathToFile(CoreOutputLocationManager.java:390)

Compile error: NullPointerException thrown: null



The log in the workspace shows me:

Comment 1 Andrew Eisenberg

The problem here is that AJDT is mistakenly assuming that there is a one-to-one mapping between jars/folders coming in on the in path and the classpath entry that they correspond to.

When working with classpath containers and other projects coming in on the in path, we need to resolve their classpaths and add each one to the mapping.

Fixed with regression tests.  Will be available in next dev build.
