Hello,
we do something similar:
GIT_MESSAGE=/tmp/git-message.txt
mvn -B -V -e -l /tmp/maven-logfile versions:use-latest-releases
versions:update-properties
cat << EOF > ${GIT_MESSAGE}
mvn -B -V -e -l /tmp/maven-logfile versions:use-latest-releases
versions:update-properties
https://git.example.com/tpq/divpom/builds/${CI_JOB_ID}
<https://git.example.com/tpq/divpom/builds/$%7BCI_JOB_ID%7D>
EOF
grep '\[INFO\] Updated ' /tmp/maven-logfile >> ${GIT_MESSAGE} && mvn -B -V -e
verify || echo "No updates detected“
Regards
Mirko
