Merge branch 'master', remote-tracking branch 'remotes/parent/master'
First Version showing Subprojects without using the dependency Graph
Merge branch 'master' of https://github.com/jenkinsci/parameterized-trigger-plugin
Test cases to show [JENKINS-14278] occuring.
Get the root build before getting the project so that we get the correct parent.

This means that when the build is one of a matrix configuration group we get the matrix parent,
and therefore when getting the project list we do so from the Item group that the parent is in,
not the child's (the matrix configurations).
Merge fixes from kinow to actually set the number of executors.
Add behaviour options for counter factory in case of invalid options.

[FIXED JENKINS-13872]
Add the possibility of skipping the triggering, or ignoring the parameters when the
to, from and step elements do not form a contained set.

Corrected an issue in the BuildTriggerConfig class where if a factory returned no parameters
meant that no projects would be triggered in certain cases.
Make the FilebuildParameter factory behave in similar way to counter factor

Add behaviour to handle cases where there are no files found in the workspace matching
expression.
This allows the following cases: failing the build, triggering without these parameters
and skip triggering of the projects if the files don't exist.
[FIXED JENKINS-15130] ‘descriptorByName/BuildTrigger’ ambiguous.
[maven-release-plugin] prepare release parameterized-trigger-2.16
[maven-release-plugin] prepare for next development iteration
Merge pull request #25 from ndeloof/master

capture build environment to expand variables in triggered job parameters
[FIXED JENKINS-14545] Correct Env variables

Extend and correct Enviroment variables that are provided when
using block until other projects are completed, in the trigger/call
other projects buildstep.

Extended vaiables to provide the full list of projects triggered, and
the full list of builds triggered when using the parameter factories.
Correct spacing in BuildInfoExporterTest file
[FIXED JENKINS-14545] Correct and add testcases for Env variables
[FIXED JENKINS-15834] Allow multiple properties files

Support the passing of multiple property files via a
comma seperated list.
Correct help messages and add behaviour to correctly
skip triggering downstream if a file is missing.
Move to hamcrest 1.3 which is in repo.jenkins-ci.org
to ease building.
Merge pull request #29 from cjo9900/hamcrest-all

Move to hamcrest 1.3 which is in repo.jenkins-ci.org
[FIXED JENKINS-13852] Allow upstream SVN parameters to be passed downstream

Added an option to allow upstream svn parameters to be passed
to downstream builds.
Excessively fragile test failed when run against 1.480 core.
Broke plugin-compat-tester.
