backwards compatible maven command line
---------------------------------------
Key: MNG-3060
URL: http://jira.codehaus.org/browse/MNG-3060
Project: Maven 2
Issue Type: New Feature
Components: Command Line
Reporter: Ryan Christianson
I work for a company that is using maven 2.0.4. We are looking at upgrading to
2.0.6, but we have many projects that might be broken by the upgrade. This
means that we need to upgrade all of our old projects, which its expensive.
I'm wondering if this could be solved by updating the command line tool to
support multiple installed versions of maven.
It might work like this:
- add a "suggested maven version" to pom.xml files (eg.
<mavenVersion>2.0.4</mavenVersion>
- update the mvn command line tool to look for the suggested version maven as
class paths like this:
- M2_HOME_2_0_4 would be maven 2.0.4, M2_HOME_2_0_6 would be 2.0.6 and so on.
- if no M2_HOME_{$VERSION} is found, then use M2_HOME
