If two Multijobs are listening for same repository, same branch and have parameters with same name but with different parameter values then only one value will be used.

Example:

• There is job1 and job2 who listen to same repository and have String parameter with same name.
• call git notifyCommit which triggers jobs:
  http://xxxxxxxxxx/git/notifyCommit?url=%2Fhome%2Fmvndev%2Fplugin_src%2Fgit-plugin%2F.git&branches=master&sha1=0895db13d1005b4a537f7fc87c3be0969c010c97

  Scheduled job1
  Scheduled job2
  No Git consumers using SCM API plugin for: /home/mvndev/plugin_src/git-plugin/.git
  

• as result triggered build use both parameters.
