How can I stop an Xcode Archive build if my git working copy is dirty?

I do not want an Archive build to succeed unless my working directory is clean. Therefore, I want to add a “Run Script” build phase (or something similar) to my Xcode project such that:

IF I am performing an Archive build…

  • How/When does Execute Shell mark a build as failure in Jenkins?
  • build trigger based on checkins to specific folder in a GIT repo in teamcity
  • Jenkins and maven-buildnumber-plugin
  • Jenkins - Promoting a build to different environments
  • How can I ignore build directory in Subclipse?
  • How to organize full build pipeline with Gulp, Maven and Jenkins, all the way to integration tests?
  • AND there are uncommitted changes in my source directory

    THEN the build fails with an error.

    I’m working with Xcode 4 and git 1.7.

    What’s a good, concise, reusable script that will do the job?

  • How to erase a published Git commit from history?
  • How can I remove an applied git patch?
  • How to change a github repo's directory to somewhere else?
  • Git Hook under Windows
  • Git (1.7.10) asks me every time for username and password
  • why config folder is not pushed?
  • One Solution collect form web for “How can I stop an Xcode Archive build if my git working copy is dirty?”

    Here’s the script I’ve come up with:

    #!/bin/sh
    if [ -z "$(git status --porcelain)" ]; then
        TAG=`date +xcarchive-%Y%m%d-%H%M%S`
        echo "Working directory clean, creating tag ${TAG}"
        git tag -a -m "Xcode Archive created" ${TAG}
        exit 0
    else
        echo "error: Working directory dirty, stopping build"
        exit 1
    fi
    

    As a bonus, it creates a tag if the working copy is clean.

    The clean/dirty check is based on this question (which I forgot I had proposed an answer for).

    If you don’t want to create a tag, remove the git tag line.

    If you don’t want to stop the build, remove the exit 1 line.

    To install this in a project:

    1. Put this in a file in your project directory (I called it ArchiveHousekeeper.sh) and make sure the executable bit is set (chmod +x)
    2. In your Xcode Project, add a new “External Build System” target
      • Name: “Archive Housekeeper” (or whatever you like)
      • Build Tool: ./ArchiveHousekeeper.sh
    3. On the Xcode menu, select Product -> Edit Scheme…
    4. In the Build section, add the new target, then uncheck all the boxes except the one in the Archive column. This ensures the script will only be run on Archive. (See this question for an explanation and a nice screenshot.)
    5. Now try to create an archive, and watch it fail because you haven’t checked in these changes!

    It would be nice if Xcode 4 Pre- and Post- actions could be used for this (so you don’t need to create a “fake” target), but they don’t seem able to affect the build, and also I have no idea in what directory they are executed, what environment variables are available, or where their output goes.
