Jacobo Jimenez commented on JENKINS-12480:
------------------------------------------
I have this situation configured but it doesnt works fine, maybe this is a kind of incompatibility between plugins:
I use "Parameterized Trigger" + "Run condition" + "Conditional build step" plugins to set a diamond execution but making the number of build in 2nd step variable (even 0) depending on the input parameters.
-One problem is that with 0 value "Counter parameter factory" crash (Java exception) so I use conditional build step to check it. By now that is working as intended but it would be nice Counter parameter factory not to crash with 0 repetitions.
-The main problem is when I launch another build it finish its main step but when it should continue to the 2nd step of the diamond it keeps waiting the downstreams builds of the other execution avoiding users to run more than 1 project at a time.
> Build step that runs multiple jobs in parallel, and blocks until all are complete

> We would like to kick off multiple test jobs as build steps, and block waiting for them all to finish. Currently the execute serially. But we have lots of available resources to run them, so it would be so nice to run them in parallel, and get the results in 1 hour, rather than many.

I believe this is a bug in the current release (2.15 and 2.16) of the Parameterized Trigger Plugin. I've downgraded to version 2.10 and it is working again properly.
The trick is to create only 1 build step, and then nest all of the triggers under that one build step so that they can all run in parallel.
