Apache Maven is a software project management and comprehension tool. Based on
the concept of a project object model (POM), Maven can manage a project's
build, reporting, and documentation from a central piece of information.
As Maven requires Maven to build, and the Apache foundation provides a
self-encompassing tarball with Maven already compiled, it is much easier to
treat this package much like we do with host-openjdk-bin.
Traditionally, Maven's installation directory is either
usr/share/maven or /usr/lib/maven with the mvn binary symlinked to /usr/bin.
This installation method keeps all of the various libraries and conf files
provided in the maven tarball separated from the rest of the host directory
and prevents any libraries from potentially overwriting previously installed
host-package libraries.
By default, Maven downloads dependency modules of a given package to ~/.m2,
which goes against Buildroot being a sandbox.
There are two options to change this path:
1) Hardcode a path in the provided settings.xml file to the desired location.
2) Set the path to a variable and pass the path via to Maven during runtime.
Option 2 has the advantage of ensuring all the paths are relocatable.
Instead of using sed on the provided settings.xml, which would be very
difficult to do, as the default settings file has the localRepository variable
commented out, a settings.xml file in package/maven-bin has the
localRepository variable pre-set to the MAVEN_REPO_DIR environment variable.
Finally, maven-bin.mk provides the MAVEN environment variable helper,
which provides all of the needed variables needed to invoke Maven in a single
command, making it much easier to integrate packages that need to use Maven.
An example of using Maven with a package would be as such:
FOO_DEPENDENCIES = host-maven-bin
define FOO_BUILD_CMDS
cd $(@D) && $(MAVEN) compile
endef
define FOO_INSTALL_TARGET_CMDS
$(INSTALL) -m 755 $(@D)/target/foo.jar $(TARGET_DIR)/usr/bin/foo.jar
endef
