Error drools - java.lang.NoClassDefFoundError: org/drools/event/KnowledgeRuntimeEventManager - java

I'm developing an eclipse plugin "jass" using the drools engine to make inferences on some concepts and displays them using an editor implemented with GEF
I added drools 5.5.0 in the build path. (knowledge-api.jar, drools-compiler.jar drolls-core.jar ecc.)
To test the operation of the engine I created a main method that retrieval engine and works well. Inverce if I run the plugin I get this error:

Can any one help how to solve this problem
Thanks

You might want to consider updating to Drools 6.x. The reason being that I assume an Eclipse plugin's runtime is an OSGI environment and I do not know if Drools 5.x is OSGI compatible, whereas Drools 6.x is definitely OSGI ready.

The Eclipse version you are using doesn't understand the ASTParser version requested by the testng plugin (from the line numbers: probably AST.JLS8, see https://github.com/cbeust/testng-eclipse/blob/master/testng-eclipse-plugin/src/main/org/testng/eclipse/util/TestSearchEngine.java)
Try upgrading to an up-to-date Eclipse version, see https://www.eclipse.org/downloads/

However, I put commons-collections-3.2.2.jar and commons-collections-3.2.2-javadoc.jar as in Build Path, so in WebContent/WEB-INF/lib: Project Explorer
Anybody knows how to solve this problem?
I had downgraded hibernate version to 4.3 via Hibernate Console Configuration and created configuration (Hibernate Perspective - Run Hibernate - Hibernate Code Generation Configuration), and it started working.

Exception . I have no idea on how to resolve this issue. Any suggestion ?
You need to include the jersey-client.jar file for the same
You can download it from here
Or if you´re using maven write:
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-client</artifactId>
<version>1.9</version>
</dependency>
Where version is the adecuate version.

Regards.
Without knowing the code, I can only tell you to look this good hierarchy of WindowsBuilder. That derived from the others and ContentPane that is well structured.

Thanks in advance for your answers
When you look at the error stack
at org.eclipse.wst.command.internal.env.common.FileResourceUtils.makeFolderPathAtLocation(FileResourceUtils.java:790)
at org.eclipse.wst.command.internal.env.common.FileResourceUtils.makeFolderPathAtLocation(FileResourceUtils.java:833)
at org.eclipse.wst.command.internal.env.common.FileResourceUtils.createFileAtLocation(FileResourceUtils.java:765)
It looks like there might be some discrepancy in creating a file/folder.
Check to see if the provided folder location exists.
If yes, then check to see if eclipse has enough permissions to create/write files/folder to the specified path.
