GitLab-CI get pom version in pipeline

Question

I'd like to build docker image via gitlab CI with project's version as a tag:

docker build -t dockerimage:VERSION-IN-POM .

In jenkins' pipeline i'm getting the version like that:

${pom.version}

Is it possible to read the version in a similar, convenient way from gitlab CI? Or do I have to write scripts for that?

Answer 1

Assuming you have maven in build environment, you could use maven help plugin and grep to extract version.

VERSION=$(mvn --non-recursive help:evaluate -Dexpression=project.version | grep -v '\[.*')
echo $VERSION

Answer 2

This work for my variable: gitlab-ci.yml

mvn -Dexec.executable='echo' -Dexec.args='${project.version}' --non-recursive exec:exec -q

Answer 3

if you know the project name, here is another approach using shell; is to cut the version from the target .jar file created under ./target directory.

Note: This will work only after successful build commands:

   cd target
   version=`ls <PROJECT_NAME>*.jar`
   version=${version#<PROJECT_NAME>} 
   version=${version%.jar}
   cd ..
   echo $version

<PROJECT_NAME> is the name of the project (use without <> marks)

Answer 4

you can use below command in your .gitlab-ci.yml :

VERSION=$(mvn --non-recursive help:evaluate -Dexpression=project.version -q -DforceStdout)

echo $VERSION

furthermore you can get groupId and artifactId by change this part Dexpression=project.version to Dexpression=project.artifactId and Dexpression=project.groupId

for more command and description you can use below link: https://maven.apache.org/plugins/maven-help-plugin/evaluate-mojo.html
