Building Maven
Why would I want to build Maven?
Building Maven yourself is for one of two reasons:
- to try out a bleeding edge feature or bugfix (issues can be found in JIRA),
- to fix a problem you are having and submit a patch to the developers team.
Note, that you don't need to bootstrap Maven for day to day use, or to develop plugins. While we encourage getting involved and fixing bugs that you find, for day to day use we recommend using the latest release.
Checking out the sources
All of the source code for Maven and its related libraries is in managed in the ASF source code repositories. Current development of the core of Maven, and some other components, are in git. Other pieces (and older versions) are in Subversion. For details, see http://maven.apache.org/source-repository.html.
Building Maven
Building a Maven Plugin or Component
Building a Maven plugin or component is like any Maven build:
mvn install
Before submitting a patch, it is advised to run the integration tests, which are available in a profile:
mvn -Prun-its install
Building Maven With Maven Installed
If you already have Maven installed, it can be faster to build a new version with Maven, rather than a clean bootstrap.
To do this, run from the source directory:
mvn install
The assemblies will be created in apache-maven, and can be unzipped to the location where you'd like Maven installed.
Running the full Maven core integration tests
Before checking in a change or submitting a patch to Maven core, it is required to run the integration tests. These live in their own git repository. Using your local build of Maven, run:
mvn install -Prun-its
