Re: [recommenders-dev] Need help to collect completion proposals made by code recommenders programetically 
Hi Marcel,
Thanks for your reply. It works and gives me the following output:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Setting up recommender and model repository (downloads search index
the first time).
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for
further details.
Query the recommender the first time (no model yet available).
Try #1: num of recs: 0
Waiting for model download to happen in background.
Exception in thread "pool-6-thread-1" java.lang.NullPointerException

	Recommendation{proposal=Ljava/lang/String.equals(Ljava/lang/Object;)Z,
probability=0.9843}
	Recommendation{proposal=Ljava/lang/String.equalsIgnoreCase(Ljava/lang/String;)Z,
probability=0.0122}
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
I am trying to understand the code. I can get the position of method
calling in a Java code. Now I need to create the right query and call
the recommender.computeRecommendations(query) method.
If I am missing something or something can help me to understand the
code, please let me know.

Thanks again for your help.

The reason is that (probably) due to the change to use package-imports rather than required-bundles some transitive dependencies cannot be resolved by Eclipse statically anymore. When running this code in an OSGI container it should work out-of-the-box. The SingleZipCallRecommender, however, should work out of the box.
