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. |
