Can you pass verbose="true" to that task so we can see a call stack if there
is one? Also...are you starting that build with StartBuildTask and
controlling it's complete lifecycle? That CompleteBuildTask is designed to
be used if you are controling the entire lifecycle of of the build using the
lifecycle(getNextBuildRequestTask, startBuildTask, etc) related ant tasks
through some process controlling the build loop. If the Jazz Build Engine
is in control of the lifecycle you should not be completing the build with
that task. The engine has control of the cycle and will progress the build
through the lifecycle as it sees fit. If you complete the build and pass in
the "buildNotNecessary=true" that will essentially delete the build from the
repository causing the engine to no longer be able to interact with it
causing a failure. Although it's not recommend that the build be manually
completed when the engine is in control of the lifecycle it is currently
tolerant of that situation which is probably why there is no error when you
simply complete it without making it not necessary. There is no guarantee
of this behavior however in the future.

Hi all,

I stop my build if there are no changes in the SVN repository. To do
this, I'm using the CompleteBuildTask. I thought, that I can use the
attribute buildNotNecessary
but I always get the error

Failed to complete
build. Build necessary = "true"

. If I
just call the CompleteBuildTask with no

buildNotNecessary

attribute,
it's working.

Whats the idea of the

buildNotNecessary

? When can it
be used and why I can't use it in my build.

Thanks for your help!

Regards,
Thomas
