mh_installjar
MAVEN(1) User Commands MAVEN(1)
NAME
Maven - Installs a jar into /usr/share/maven-repo.
SYNOPSIS
mh_installjar [option]... [pom] [jar] [link]...
DESCRIPTION
Installs the jar file in /usr/share/maven-repo, at the correct location for Maven. The jar is copied into the build directory. It can also
create additional links to the jar, usually located in /usr/share/java.
Where
[pom] is the location of the POM associated with the jar to install.
GroupId, artifactId and version will be extracted from this file.
[jar] is the path to the jar to install, usually located in the build
folder.
[link] is an additional link to the jar to install, usually there should
be a link to usr/share/java/$jar.jar and usr/share/java/$jar-$version.jar to comply with the Java packaging guidelines. Note that
there is no need to specify those particular links if the --java-lib option is used.
OPTIONS
-h --help: show this text
-V --version: show the version
-p<package> --package=<package>: name of the Debian package which
will contain this jar file
-e<version>, --set-version=<version>: set the version for the jar,
do not use the version declared in the POM file.
-r<rules> --rules=<rules>: path to the file containing the
rules to apply when cleaning the POM. Optional, the default location is debian/maven.rules Maven rules are used here to extract the
groupId, artifactId and version from the POM file.
-l --java-lib: Optional, if given it will install the jar into
/usr/share/java to comply with the Debian Java specification. The jar will be installed as /usr/share/java/$name-$version.jar and a
versionless link /usr/share/java/$name.jar will point to it, as well as the links installed in /usr/share/maven-repo
-n<name> --usj-name=<name>: Optional, the name to use when installing the
library in /usr/share/java when --java-lib is used. Defaults to the artifact id found in the POM.
-j<version> --usj-version=<version>: Optional, the version to use when
installing the library in /usr/share/java when --java-lib is used. Defaults to the version found in the POM.
-s --no-usj-versionless: Optional, don't install the versionless link
in /usr/share/java. This flag is used only when the -l or --java-lib option is given.
-d<path> --dest-jar=<path>: Optional, the destination for the real jar.
The other places where the jar appears, in the repository or in the list of links, will be symlinks to this jar. Defaults to
/usr/share/java/$name-$version.jar if --java-lib is used, otherwise the jar is installed in the versioned path in the Maven reposi-
tory.
-c<classifier> --classifier=<classifier>: Optional, the classifier for
the jar. Empty by default.
-v --verbose: show more information while running
-n --no-act: don't actually do anything, just print the results
--skip-clean-pom: don't clean the pom, assume that a previous action ran
mh_cleanpom with the correct options. mh_cleanpom is run only to extract the groupId, artifactId and version of the jar
