@end defvr
@defvr {Scheme Variable} maven-build-system
This variable is exported by @code{(guix build-system maven)}. It implements
a build procedure for @uref{https://maven.apache.org, Maven} packages. Maven
is a dependency and lifecycle management tool for Java. A user of Maven
specifies dependencies and plugins in a @file{pom.xml} file that Maven reads.
When Maven does not have one of the dependencies or plugins in its repository,
it will download them and use them to build the package.
The maven build system ensures that maven will not try to download any
dependency by running in offline mode. Maven will fail if a dependency is
missing. Before running Maven, the @file{pom.xml} (and subprojects) are
modified to specify the version of dependencies and plugins that match the
versions available in the guix build environment. Dependencies and plugins
must be installed in the fake maven repository at @file{lib/m2}, and are
symlinked into a proper repository before maven is run. Maven is instructed
to use that repository for the build and installs built artifacts there.
Changed files are copied to the @file{lib/m2} directory of the package output.
You can specify a @file{pom.xml} file with the @code{#:pom-file} argument,
or let the build system use the default @file{pom.xml} file in the sources.
In case you need to specify a dependency's version manually, you can use the
@code{#:local-packages} argument. It takes an association list where the key
is the groupId of the package and its value is an association list where the
key is the artifactId of the package and its value is the version you want to
override in the @file{pom.xml}.
Some packages use dependencies or plugins that are not useful at runtime nor
at build time in Guix. You can alter the @file{pom.xml} file to remove them
using the @code{#:exclude} argument. Its value is an association list where
the key is the groupId of the plugin or dependency you want to remove, and
the value is a list of artifactId you want to remove.
You can override the default @code{jdk} and @code{maven} packages with the
corresponding argument, @code{#:jdk} and @code{#:maven}.
The @code{#:maven-plugins} argument is a list of maven plugins used during
the build, with the same format as the @code{inputs} fields of the package
declaration. Its default value is @code{%default-maven-plugins} which is
also exported.
@end defvr
@defvr {Scheme Variable} minify-build-system
This variable is exported by @code{(guix build-system minify)}. It
implements a minification procedure for simple JavaScript packages.
