Jenkins Cobertura build - NoClassDefFoundError

Question

I have a test class ProcessorTestwith lines

JSONObject jsonObj = XML.toJSONObject(convert);
DBOb = (DBObject) JSON.parse(jsonObj.toString());

The XML class is located in json.org . The class is used differently where in the code without problems.

Everything works fine on localhost (i.e. all Maven and JUnit tests run).

When I clicked on Jenkins, I get this error:

Jenkins Error

I am using Jenkins 1.553 and the Cobertura 1.9.6 plugin.

How to fix it?

The structure of the project is as follows:

-- project1
     |
     | - core
     | - Tests (includes the tests that fail)


-- org.json
     |
     | - XML.class

When I click on Jenkins, I assume that the project is org.jsonnot available for tests.

Answer 3

Maven Jenkins, . , cobertura-maven-plugin pom.xml.

Cobertura library ( maven ) , Cobertura Jenkins. asm.jar . , jenkins.

, ( , org.json):

• latest version of Jenkins 1.596in conjunction with Jenkins Cobertura-Plugin1.9.6
• latest cobertura-maven-pluginmaven plugin for various projects in version2.6

My strong assumption: this is not about the material itself JSON, but about the environment of your installation; your version of Jenkins is a 1.553bit outdated. I would advise you to upgrade if possible with administrators / other projects.
