Support for .mvn/maven.config

[fabapp2]

What needs to be done

Maven can be configured using a file .mvn/maven.config to define system parameters which will be passed to every mvn command.

Why it needs to be done

In CWA-Server a property revision is defined in pom.xmls.
This property needs to be resolved using OpenRewrite.
Looking into getPom().getValue(...) showed that only some standard properties are resolved by their keys and if these are not found it's looked up using System.getProperty().
The simplest way to allow a lookup using getValue() would be to add all system properties defined in .mvn/maven.config as system properties during parsing.

Acceptance Criteria

Given

.mvn/maven.config

-Dsome.property=some-value

pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>example.com</groupId>
    <artifactId>module</artifactId>
    <version>0.1.0</version>
    <properties>
        <resolved.value>${some.property}</resolved.value>
    </properties>
</project>

When

• The pom was parsed

Then

• The property resolved.value should have the value some-value
