How to update the maven version without pom backup files

Question

How do you run maven with the versions plugin to update the version inside several pom.xml files and not get the annoying pom.xml.versionsBackup files? (I have my poms in version control, so I don't need a backup).

I run this command to update the version:

mvn versions:set -DnewVersion=3.8.0-SNAPSHOT

adding .versionsBackup to .gitignore is also useful – Lovesick

Answer 1

To prevent creating backup files, use generateBackupPoms instead:

mvn versions:set -DgenerateBackupPoms=false -DnewVersion=3.9.0-SNAPSHOT

I also saw that you can set up generateBackupPoms in the plugin section of a pom.xml if you want to do it that way.

Note if you are using eclipse, you can run the command using a run configuration like this:

That helped, but a tip: with -DnewVersion=${string_prompt} eclipse presents a dialog for you to enter the version number, so you don't need to update your run configuration all the time (I also put the -D parameters to the Parameters further down, without the -D there). I think its much more convenient. – Centenarian

only problem: if you hit cancel that prompt (escape), it still runs and does useless bogus. Would like to have a way to catch that cancel, but failed to find one. If anyone knows, please respond here. – Centenarian

Awesome, would be nice to know if we can do this in Intellij too. I'll start searching. – Coulombe

Its not working on my jenkins machine. I am using -DgenerateBackupPoms=false but still backup poms are created. This is my command -> mvn build-helper:parse-version versions:set \ -DnewVersion=\\\${parsedVersion.majorVersion}.\\\${parsedVersion.minorVersion}.\\\${parsedVersion.nextIncrementalVersion}-SNAPSHOT -DprocessAllModules -DgenerateBackupPoms=false – Eagleeyed

In Eclipse, the newVersion=${string_prompt} will only work if you add in the Parameter section below, but it works. – Purposeless

Answer 2

After mvn versions:set, run the command mvn versions:commit.

All of the pom backups will be deleted.

Answer 3

mvn versions:set -DgenerateBackupPoms=false deletes the backups and will also ask the new version to be set instead of passing the version in the command.

Answer 4

mvn -B versions:set -DnewVersion=${APP_VERSION} -DgenerateBackupPoms=false
