NoClassDefFoundError of dependent jar class during process execution in BPMS

Issue

• There is a kjar which depends on a jar. And the jar has dependency on Spring. It is expected that the transitive dependencies will be resolved by maven. But when the process is executed, the Script Task fails with NoClassDefFoundError as shown below.
  How to fix this issue?
