Eclipse 使用Maven 更改项目版本？

Question

I heard it's possible to change the version of a project using Maven. I am talking about the tag <version>1.1</version> in the project "pom.xml" and all the pom file of all the sub project.

I want to do that because some project may have a lot of subproject and do it manually can be real losse of time.

I am using eclipse if any of you know if it's even possible and if it is, how to do it?

Thanks in advance

Answer 1

You can do that via the versions-maven-plugin via the following from the root of your project:

mvn versions:set -DnewVersion=1.2-SNAPSHOT

This will change all the versions in your pom files also of all your childs. It will left over some backup file. This can either being solved by using the following:

mvn versions:commit

or maybe even better by starting with this:

mvn versions:set -DnewVersion=1.2-SNAPSHOT -DgenerateBackupPoms=false
