Reproduce Jenkins builds locally

[j-rivero]

Steps that I usually run manually to reproduce jenkins:

debbuilder builds

1. Download Dockerfile and build.sh (wget) from artifacts archived in the Jenkins run to reproduce
2. chmod +x build.sh
3. Docker build in the same way is being done in the build log (changing tag to test):

   docker build --build-arg GID=1001 --build-arg USERID=1001 --build-arg USER=jenkins --tag test .

4. Docker run to go into the container

   docker run -i -t test /bin/bash

5. Inside the container, some tweaks to deal with Jenkins paths (replace foo with debbuilder name):

   mkdir -p /home/jenkins/workspace/$foo-debbuilder/build

6. Run build.sh (need to use bash):

   bash -x build.sh

other builds
Need to deal with git checkouts done in Jenkins that usually goes under: $WORKDIR/$software_name . The git checkouts are usually linked to input parameters in PARAMS such as sha1, DEST_BRANCH or similar.

i.e:/home/jenkins/workspace/ignition_gazebo-abichecker-any_to_any-ubuntu_auto-amd64/ign-gazebo

Looks like it is possible to run git init in $WORKDIR/$software_name and after that parse the build log for git commands starting with > at the beggining of the log and reproduce the actions of the plugin.
