NullPointerException when running AstorMain.execute(args)

[javierron]

I have traced the issue and it seems that the location configuration property is being required here: https://github.com/SpoonLabs/astor/blob/352355e4e9f335427a75cd78303e3d37064802c6/src/main/java/fr/inria/main/AbstractMain.java#L378

https://github.com/SpoonLabs/astor/blob/352355e4e9f335427a75cd78303e3d37064802c6/src/main/java/fr/inria/astor/core/setup/ProjectConfiguration.java#L274

Before being stored in the properties map here:

Hi @javierron Do you have the command you use to launch Astor? Thanks Matias

Sure, you can see the call here:

https://github.com/eclipse/repairnator/blob/4fc54a2194a6def3785ea1a51a3bfb9efb2e68fc/src/repairnator-pipeline/src/main/java/fr/inria/spirals/repairnator/process/step/repair/sequencer/detection/AstorDetectionStrategy.java#L52

This worked on version 20190919, but breaks in version 1.0.0-SNAPSHOT after I upgraded to get the fix for the GZoltar exception.

Hi Javier Do you have the stack trace of the NPE? Thanks! Regards Matias
