Goal

Modify compiler for maven projects to use non javac compiler.

Non Goal

Modify entire pom or other plugins.

Install

⚠️ minimal required maven version is 3.6.3 Follow

Configure for all projects

Or add jar file in ${maven.home}/lib/ext/ (enables for all projects)

Configure for specific project

just create or update ${basedir}/.mvn/extensions.xml file

<extensions xmlns="http://maven.apache.org/EXTENSIONS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/EXTENSIONS/1.0.0 http://maven.apache.org/xsd/core-extensions-1.0.0.xsd">
    <extension>
        <groupId>me.qoomon</groupId>
        <artifactId>maven-git-versioning-extension</artifactId>
        <version>5.2.0</version>
    </extension>
</extensions>

Usage

Follows profile behaviour like we have in maven. User can define multiple profiles in ~/.m2/compile-config.xml.

To activate particular profile java8 pass -Decj-native=java8 while running $ mvn compile. extension expects ~/.m2/compile-config.xml to have something like this.

Schema for compile-config.xml is defined here

sample config

<!-- <?xml version="1.0" encoding="UTF-8"?> -->
<profiles>
  <profile id="java8">
    <configuration>
      <fork>true</fork>
      <executable>/usr/bin/javac</executable>
