Maven.config from start scripts

Merely a draft for:

From MNG-7193:

MAVEN_ARGS is overwritten by maven.config is overwritten by CLI arguments.

However, if I build Maven on this branch and test with

$ cat .mvn/maven.config 
-V
-DskipTests=true

$ MAVEN_ARGS="-DskipTests=false" mvn test 

I get

[INFO] -------------------------------------------------------
[INFO]  T E S T S
[INFO] -------------------------------------------------------
[INFO] Running foo.AppTest
[INFO] Tests run: 1, Failures: 0, Errors: 0, Skipped: 0, Time elapsed: 0.023 s - in foo.AppTest

Since maven.config should have precedence over MAVEN_ARGS, I would expect the tests to be skipped. If I use the same maven.config and run mvn test (without MAVEN_ARGS) the tests are skipped, as expected.

I did a second test, where a Maven profile upgrades a plugin; it shows the same behaviour: MAVEN_ARGS "wins" from .mvn/maven.config, despite MNG-7193 saying the reverse.

Let me get in touch with you later this week about this.

You're right. It was written before we have agreed on option 7 in https://cwiki.apache.org/confluence/plugins/servlet/mobile?contentId=186877056#content/view/186877056. I will rework.
