The purpose of this is to visualize the git status output after git fetch, to identify possible problems that are stalling the build.
On a recent travis build stall, got this message from the downloadDeps.sh script plugin runs:
[ERROR]
org.eclipse.jgit.errors.RevWalkException: Walk failure.
Caused by: org.eclipse.jgit.errors.MissingObjectException: Missing commit 6e06855
If fetching is actually having problems on some runs, the output of git status should provide more insight on it.
