Running maven goals from Java without a Maven executable installed on the machine

Question

I am trying to build a project to checkout code from SCM and build it using maven. Is there a way we can achieve running maven goals from java without a maven home being provided(no maven installation). For SVN, I am using svnkit to achieve the same. For maven, I tried using the below 2 options.

http://maven.apache.org/ref/3.0-beta-3/maven-embedder/ Can anyone give a good example of using org.apache.maven.cli.MavenCli programattically?

For both the above options, I need to have a maven installation. Any suggestions?

Answer 1

No, just include the jar in your project and the following, to compile code:

MavenCli cli = new MavenCli();
int result = cli.doMain(new String[]{"compile"},
        "workspace/MiscMaven",
        System.out, System.out);
System.out.println("result: " + result);

Per a comment, here's how you add the dependency to your project. This does not install maven on your system, merely includes the JARs in your project build:
