Apache Maven is a general-purpose build system that does not rely on Makefiles to build software. It is designed for building and managing and Java-based project.


The MavenBuilder and MavenPackage base classes come with the following phases:

  1. build - compile code and package into a JAR file

  2. install - copy to installation prefix

By default, these phases run:

$ mvn package
$ install . <prefix>

Important files

Maven packages can be identified by the presence of a pom.xml file. This file lists dependencies and other metadata about the project. There may also be configuration files in the .mvn directory.

Build system dependencies

Maven requires the mvn executable to build the project. It also requires Java at both build- and run-time. Because of this, the base class automatically adds the following dependencies:

depends_on("java", type=("build", "run"))
depends_on("maven", type="build")

In the pom.xml file, you may see sections like:


This specifies the versions of Java and Maven that are required to build the package. See for a description of this version range syntax. In this case, you should add:

depends_on("java@7:", type="build")
depends_on("maven@3.5.4:", type="build")

Passing arguments to the build phase

The default build and install phases should be sufficient to install most packages. However, you may want to pass additional flags to the build phase. For example:

def build_args(self):
    return [
