Hello All,
I am working on Jenkins Plugin Development. I have a special Job type,
that creates Free Style Projects on saving of the Project.
e.g: Jenkins > New Item/New Job > Enter Name (say "Special Project") and
click "Build a Special Project" radio button > Click Save. On Clicking
Save, the Free Style Projects (child Projects) would be created using
the below code:
|FreeStyleProject childProject =
Jenkins.getInstance().createProject(FreeStyleProject.class,"newName");
FreeStyleProject childProject1 =
Jenkins.getInstance().createProject(FreeStyleProject.class,"newName1");

I would like to trigger these childProject, childProject1 jobs when my
"Special Project" is given a build (say by timer or by clicking "Build Now")
I tried the below code , but I get exception.

Also, I had gone through the MultiJob Jenkins Plugin
https://wiki.jenkins-ci.org/display/JENKINS/Multijob+Plugin
<https://wiki.jenkins-ci.org/display/JENKINS/Multijob+Plugin> . But,
there all the child jobs are executed via a separate Thread and not via
Executors.
Could someone help me in this issue?
Thank you in advance!!
