maven override project.version from command line

Question

I wonder if it is possible to override project.version/version variable in maven via command line?

The following doesn't work:

mvn deploy -Dversion=1.0-test-SNAPSHOT   mvn deploy -Dproject.version=1.0-test-SNAPSHOT   

Thanks in advance for your help!

My pom.xml is:

<project>     <modelVersion>4.0.0</modelVersion>     <groupId>just.another.company.name</groupId>     <artifactId>my-pom</artifactId>     <version>1.3-SNAPSHOT</version>     <name>My Module</name>     <packaging>jar</packaging>     <description>POM Project for My Module</description> </project> 

Answer 1

In Maven 3.5+, if you put the following in your pom.xml

<version>${revision}</version> ... <properties>     <revision>1.0.0-SNAPSHOT</revision> </properties> 

it will use 1.0.0-SNAPSHOT by default, but you can override it on the command line:

mvn -Drevision=2.0.0-SNAPSHOT clean package 

Apparently this only works if the placeholder property is called revision (you can also use changelist and sha1 placeholders in your version).

See https://maven.apache.org/maven-ci-friendly.html

Answer 2

Simply you can't override project.version. Try:

mvn versions:set -DnewVersion=<version> 

Usually, I start by updating the parentPom

mvn versions:set -DnewVersion=1.0.3-SNAPSHOT 

This would be enough if the parent pom contained all child projects if not you will need to go to a super project that contain all child project and execute

mvn versions:update-child-modules 

Also the two previous steps will be enough if the parentPom exists in relative path if not you will need to install parentPom project with the new version

mvn install 

Usually this will be enough if you don't have module depend on another module. if you do, declare its version as a project.version like that and it will be reflected automatically

<version>${project.version}</version> 

Check the maven Versions Plugin docs.
