No such method org.apache.uima.cas.impl.TypeSystemImpl.createCallSite

[Alain Désilets]

I am trying to use the bleeding edge version of dkpro-core (2.0.0-SNAPSHOT) in my project.

I have been able to build it, but when I run my project's unit tests, I get a bunch of errors which are generated when a JCas is generated. The errors look like this:

---------
java.lang.NoSuchMethodError: org.apache.uima.cas.impl.TypeSystemImpl.createCallSite(Ljava/lang/Class;Ljava/lang/String;)Ljava/lang/invoke/MutableCallSite;
at de.tudarmstadt.ukp.dkpro.core.api.frequency.tfidf.type.Tfidf.<clinit>(Tfidf.java:59)
at de.tudarmstadt.ukp.dkpro.core.api.frequency.tfidf.type.Tfidf_Type.<clinit>(Tfidf_Type.java:43)
at java.lang.Class.forName0(Native Method)
etc...
at org.apache.uima.fit.factory.JCasFactory.createJCas(JCasFactory.java:103)
etc...
---------

or like this

---------
java.lang.NoClassDefFoundError: Could not initialize class de.tudarmstadt.ukp.dkpro.core.api.frequency.tfidf.type.Tfidf_Type
at java.lang.Class.forName0(Native Method)
etc...
at org.apache.uima.fit.factory.JCasFactory.createJCas(JCasFactory.java:103)
etc...
---------

So obviously, createJCas() eventually ends up trying to create an instance of class Tfidf_Type, and this class does not exist. But I have searched through my whole Eclipse workspace (which includes all of dkpro-core and its modules) for an occurence of 'Tfidf_Type' and I can't find one.

The strange thing is that if I created a brand new Maven project which contains, then I am able to invoke createJCas() without problems.

Any idea what is going on here?

Thx.

This version builds against UIMAv3. If you want to use other DKPro projects like e.g. DKPro Similarity, it is a good idea to stick to the 1.11.x branch for the time being.

Probably you are mixing UIMAv2 and UIMAv3 code.
