maven: Is it possible to override location of local repository via the use of command line option or env variable?

Question

Currently we specify the location of local repository in the settings.xml. Is it possible to override this setting via command line or env variable, such that I can use an alternative location sometimes?

Answer 1

Use the localRepository setting in your settings.xml file. Example:

<settings>
  <localRepository>/repo</localRepository>
  ...
</settings>

See here for more info.

You can also set the repository via the command line using "-Dmaven.repo.local=" such as:

mvn -U clean install -Dmaven.repo.local=C:\tmp

Answer 2

You would need to specify the maven.repo.local parameter to do this.

mvn package -Dmaven.repo.local=/alternate/repo/location
