Indexgenerator throws NullPointerException #126

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. import sql files into the database
2. run CREATE UNIQUE INDEX revisionIdx ON revisions(RevisionID); CREATE INDEX 
articleIdx ON revisions(ArticleID);
3. create config file for Indexgenerator (realize, that the 
nullpointerexception comes from the lack of a full path for the outputfile)
4. run  java -cp 
de.tudarmstadt.ukp.wikipedia.revisionmachine-0.9.2-jar-with-dependencies.jar 
de.tudarmstadt.ukp.wikipedia.revisionmachine.index.IndexGenerator 
indexgenerator.conf

What is the expected output? What do you see instead?
GENERATING INDEX STARTED
java.lang.NullPointerException

The steps you mention work just fine on my machine. Must be either a problem in 
your config or with the location of the config file, which has to be in the 
classpath.
