ctakes uimafit analysis engine resource initialization errors

[Jay Urbain]

I'm trying to run the AggregatePlaintextUMLSProcessor AE in Eclipse.
- ctakes 3.2.3-SNAPSHOT

I'm getting ctakes uimafit analysis engine resource initialization errors.

First, I have no compile errors, and I'm using the developer version of
ctakes "out of the box," i.e., with know modifications except correcting
maven dependency errors.

I've been struggling resolving the following
ResourceInitializationException:

3/1/16 5:31:44 AM - 18:
org.apache.uima.tools.cvd.MainFrame.handleException(526): SEVERE:
Initialization of annotator class
"org.apache.ctakes.assertion.medfacts.cleartk.HistoryCleartkAnalysisEngine"
failed.  (Descriptor:
file:/Users/jayurbain/Dropbox/apache-ctakes-3.2.2/desc/ctakes-assertion/desc/analysis_engine/HistoryCleartkAnalysisEngine.xml)
org.apache.uima.resource.ResourceInitializationException: Initialization of

failed.  (Descriptor:
file:/Users/jayurbain/Dropbox/apache-ctakes-3.2.2/desc/ctakes-assertion/desc/analysis_engine/HistoryCleartkAnalysisEngine.xml)

The failure is caused by:
Caused by: java.lang.ClassNotFoundException:
org.cleartk.ml.liblinear.LibLinearStringOutcomeClassifierBuilder
at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

... 61 more

The code fails here:

public class HistoryCleartkAnalysisEngine extends
AssertionCleartkAnalysisEngine {

boolean USE_DEFAULT_EXTRACTORS = false;
@Override
public void initialize(UimaContext context) throws
ResourceInitializationException {
super.initialize(context); // <--- fails here ---
probabilityOfKeepingADefaultExample = 0.5;
initialize_history_extractor();
initializeFeatureSelection();
}

In the past, I've been able to fix these errors by fixing a missing
dependency or by adding a specific version declaration to a dependency.

Here's the declaration in AggregatePlaintextUMLSProcessor.xml:

     <delegateAnalysisEngine key="HistoryCleartkAnalysisEngine">
      <import
location="../../../ctakes-assertion/desc/analysis_engine/HistoryCleartkAnalysisEngine.xml"/>

The HistoryCleartkAnalysisEngine.xml is automatically generated by uimaFIT.

I have the cleartk-ml-liblinear-2.0.0.jar in my .m2 repository.

I have the following dependency in the ctakes-assert and the
ctakes-clinical-pipeline pom.xml:

<dependency>
<groupId>org.cleartk</groupId>
<artifactId>cleartk-ml</artifactId>
<version>2.0.0</version>
</dependency>

Any guidance would be apprecaited.

Thanks,
