Determine which Repo triggered a build

Hello,

I have a build plan that has multiple Git Repos. I also have a polling trigger setup that checks all of them. if any of them have new commits, the build triggers. this works great.

what i need, is a way to determine from environment and/or bamboo variables, which repo triggered the build. currently bamboo gives me every repo's info in the form of "bamboo_planRepository_#_key=value"

This information is available on the build summary page in the commit section as seen below

Hi @Ari_Mahpour

You could get this information by comparing revisions of each source repository. You will need to check the following Bamboo variables:

bamboo_planRepository_#_revision
bamboo_planRepository_#_previousRevision

Considering this could be a pain for you I spent some time to build a bash shell script to do this. It is just an example of how this could be done. Please be careful with a loop like this since it can hold your build in running state forever.

echo ===========================================================
i=1
while true
do
   repoRevision='bamboo_planRepository_'$i'_revision'
   prevRepoRevision='bamboo_planRepository_'$i'_previousRevision'
   if [ -z "${!repoRevision}" ]; then
      break
   else
      repoRevision=$repoRevision
      prevRepoRevision=$prevRepoRevision
      if [ ${!repoRevision} != ${!prevRepoRevision} ]
      then
        repoName='bamboo_planRepository_'$i'_name'
        repoBranch='bamboo_planRepository_'$i'_branch'
        echo 'The repository '${!repoName}' ('${!repoBranch}') was updated'
        echo 'Revision: '${!repoRevision}
        echo 'Previous revision: '${!prevRepoRevision}
      fi
      i=$(( $i + 1 ))
    fi
done
echo ===========================================================

⚠️It will not work for Windows. In case you run windows agents you will need to design a similar script for using a windows shell of your preference.

The output should be something like:

19-Jun-2019 18:24:24 ===========================================================
19-Jun-2019 18:24:24 The repository javahello (master) was updated
19-Jun-2019 18:24:24 Revision: c3df16947412c1ca69f9e58998d8dd645221f8f5
19-Jun-2019 18:24:24 Previous revision: 55db9a76e132b853c2309aa2cf6c1963e53f06f4
19-Jun-2019 18:24:24 ===========================================================

I hope that helps you to achieve what you want.
