How to tell maven to get MAVEN_OPTS from specific file?

Question

mvn command, among others, have following options:

• -f,--file <arg> Force the use of an alternate POM file. (This is for pointing file instead of default pom.xml file.)
• -gs,--global-settings <arg> Alternate path for the global settings file. (This one is for pointing the settings.xml file, which is by default in .m2 directory.)

Still there is yet one config file uncovered by these options - .mavenrc

So, my question is - Is there a way to tell maven from which file it should get MAVEN_OPTS?

Answer 1

Starting with Maven 3.3.1, you can put these settings into the .mvn/maven.config file in your project repository.

Answer 2

MAVEN_OPTS is a environment variable from the OS. You can set it anyway you want before launching maven.

In bash (linux):

export MAVEN_OPTS=...

On windows:

set MAVEN_OPTS=...

I think you could even edit the 'mvn' of 'mvn.bat' shell script to get different variables.
