Maven - Cleans a POM file.
mh_cleanpom [option]... [pom] [target] [pom-props]
Cleans the POM and prepare it for inclusion in the Maven repository.
Also extracts some information from the POM.
[pom] is the location of the POM file to clean.
Default to pom.xml or debian/pom.xml
[target] is where the cleaned POM is written to.
Default to debian/.mh/pom.xml
[pom-props] is where the POM properties file will be written.
Default to debian/.mh/pom.properties
-h --help: show this text
-V --version: show the version
-p<package> --package=<package>: name of the Debian package containing
-o --no-parent: don't inherit from a parent POM
-k --keep-pom-version: keep the original version of the POM but,
convert all other versions in dependencies and plugins
-e<version>, --set-version=<version>: set the version for the POM,
do not use the version declared in the POM file.
-r<rules> --rules=<rules>: path to the file containing the
extra rules to apply when cleaning the POM. Optional, the
default location is debian/maven.rules
-u<rules> --published-rules=<rules>: path to the file containing the
extra rules to publish in the property debian.mavenRules in the
cleaned POM. Optional, the default location is
-i<rules> --ignore-rules=<rules>: path to the file containing the
extra rules use to remove certain dependencies from the cleaned
POM Optional, the default location is debian/maven.ignoreRules
-c<rules> --clean-ignore-rules=<rules>: path to the file containing the
rules use to remove certain dependencies from the cleaned POM,
in addition to the ignore rules specified previously. This is
useful in situations such as when the Maven clean target
requires more dependencies or plugins to ignore than the build
target Optional, the default location is
-s --no-rules: don't apply any rules for converting versions,
do not even convert versions to the default 'debian' version
-m<repo root>--maven-repo=<repo root>: location of the Maven
used to force the versions of the Maven plugins used in the
current POM file with the versions found in the repository
-v --verbose: show more information while running
-n --no-act: don't actually do anything, just print the results
Cleans a Maven POM and prepare it for inclusion in the Debian
repository for Maven.
The POM will be normalised, and its parent tag removed if the
option --no-parent is given. The version will be replaced by
'debian', unless a special rule applies (see below the
discussion about rules). Build, profiles and other build time
only sections of the POM will be stripped.
If versions are given for a dependency, this version will be
replaced by the 'debian' version, or a rule can be given to use
a custom version
You can modify those defaults with the help of the rules file.
This file should contain the lines with the format: <groupId>
[artifactId] [type] [version] [scope] where groupId, artifactId,
type, version and scope can be the explicit attribute to match,
or can contain a wildcard (*) for generic matches.
Each one of those elements can also be a replace rule, of the
form s/<regex>/<replace>/ where regex is a regular expression,
and replace is the replacement. Substitution groups ... can be
used in the replacement if capture groups () have been used in
The first element is mandatory (groupId), but you can ignore the
elements on the right hand side. If the scope is missing, then
any scope is matched and left unchanged. If the version is
missing, then any version will be replaced with 'debian'. If
type is missing, then any type is matched and left unchanged.
If artifactId is missing, then any artifactId is matched and
You can also have comments in this file, it should be a line
starting with #
Example of a rules file:
s/commons-(.*)/org.apache.commons.commons/ org.itext * *
s/1\..*/1.x/ org.itext * * s/2\..*/2.x/ # use the alpha version
of plexus-container-default org.codehaus.plexus
plexus-container-default jar s/1\.0-alpha.*/1.0-alpha/
This rules file does the following: - all groupIds starting with
commons- will have - org.apache.commons. prefixed to them - any
artifact in the org.itext group with a version number starting
with 1. will use the 1.x version
- any artifact in the org.itext group with a version number
with 2. will use the 2.x version
- the jar with groupId=org.codehaus.plexus and
artifactId=plexus-container-default and a version starting with
1.0-alpha- will use the 1.0-alpha version
The default rule (* * * s/.*/debian/ *) replaces any version
number with the 'debian' version and always applies last if
there was no other matches. Another default rule (* *
maven-plugin * *) keep the version for all plugins as the plugin
mechanism requires a version in Maven.
