Fixed Issue Summary: A bug with handling maven dependencies in kie-ci occurred in which only direct dependencies of the project were taken, but the transitive dependencies were not. This would result in the following error: java.lang.NoClassDefFoundError: org/springframework/context/ApplicationContext This issue has been resolved with 6.0.3, and the script runs without errors.

Description Toshiya Kobayashi 2014-05-15 05:47:48 UTC 
Description of problem:

This is the same projects as BZ1097632. (The difference: I applied Maciej's suggestion in comment#4. And edited jbpm-spring-dep-kjar/pom.xml as below)

(A) Jar which uses Spring
(B) Kjar which includes BPMN2 process which depends on (A) jar.
(C) A main application which runs a process in (B) kjar.

Please look into jbpm-spring-dep-test/jbpm-spring-dep-kjar/pom.xml 

I comment-out <dependency> for Spring libraries because (B) kjar just depends on (A) jar and I expect transitive dependencies will be resolved by maven.

But when I run the process, Script Task fails with NoClassDefFoundError.

Maciej, might this be solved by similar previous fixes?
Comment 3 Maciej Swiderski 2014-05-15 11:05:51 UTC 
this was indeed a bug with handling maven dependencies in kie-ci as it was only taking the direct dependencies of the project and not including transitive dependencies.
