原因
A problem is related with   BAM-13208 - Getting issue details... STATUS  .
When automatic Clover integration is selected, all Maven tasks defined in a Job are enhanced by new set of goals/phases (like "clean clover:setup verify clover:aggregate clover:clover") which are being appended at the end of the original Maven command defined in the task(s). Due to a fact that:
Maven performs build module-by-module and not phase-by-phase (for example: if a project has module A and module B and you run 'mvn clean package' then Maven runs first 'clean package' for module A, and next 'clean package' for module B) and that
Clover's automatic integration in Bamboo calls the "verify" phase
it causes that the same build phases are called twice - once without Clover and once with Clover. In our example, goals "mvn clean package" are changed to "mvn clean package clean clover:setup verify clover:aggregate clover:clover".
 
In this case, a maven-assembly-plugin running in a build phase without Clover (i.e. before the clover:setup) is trying to access resources from dependent modules, which have been already instrumented by Clover (i.e. created in the phase after clover:setup). As a consequence, Maven Assembly Plugin fails accessing files like:
