Errors during installation

[marsaoua]

I tried to test the code by using the "Install the add-on by changing two poms and the message catalog" and ran into these issues:

1. The ID: duplicate-detection from dspace/config/item-submission.xml is not recognized. This error is thrown:
   The Submission process config named traditional contains a step with id=duplicate-detection. There is no step with this 'id' defined in the 'step-definition' section of 'item-submission.xml'.

2. After removing the ID the following error is thrown:

ERROR org.dspace.app.util.SubmissionInfo @ Error loading progress bar information from Step Class 'org.dspace.submit.step.DuplicateDetectionStep' Error:
java.lang.NullPointerException
at org.dspace.submit.step.DuplicateDetectionStep.<init>(DuplicateDetectionStep.java:78)
....

The second error is simply solved by copying the "duplication-detection-service.xml" file in the appropriate DSpace-installation directory: dspace-install/config/spring/api.

Thereafter, everything worked fine as it supposed to!
