Deb Maven Plugin

Maven plugin for creating .deb packages, creating control file, copyright file and transitively copying runtime dependencies.

Plugin is platform-independent and does not require additional external tools.

Requires java 8 and maven 3.3

Plugin is available from central maven repository. To use it, simply add the following to a the pom file.

<packaging>deb</packaging>
<build>
    <plugins>
        <plugin>
             <groupId>io.solit.maven</groupId>
             <artifactId>deb-maven-plugin</artifactId>
             <version>1.0-RC2</version>
             <extensions>true</extensions>
        </plugin>
    </plugins>
</build>

Goals:

• pupulate - transitively copy runtime dependencies to a specified directory
• data - copy files to a staging and control directories
• copyright - create a machine readable copyright file
• man - compile a man pages from markdown source files
• changelog - copy and/or convert changelog to debian format
• package - create a .deb file with control file

Details:

deb packaging

Projects with packaging deb will produce a regular jar file as usual, but then will additionaly pack it into a deb file along with transitive compile and runtime dependencies, and generated content like changelogs and man pages. Source files by default are processed as follows (relative to project basedir):

• changelog.md will be converted to a changelog
• src/deb/doc/**/*.md will be converted to a man page
• content of src/deb/data will be recursively copied to a package root
• content of src/deb/control will be recursively copied to a control section of a package

populate goal

During this goal execution plugin will traverse all runtime dependencies of this project possibly applying filters to exclude some ot them.

        </packageExclusions>
    </configuration>

• dependencyDir - directory to copy dependencies to; if unspecified <stageDir>/usr/share/<packageName> will be used
• packageName - name of a debian package; default is project artifact id; may be set using deb.name system property
• stageDir - directory to stage files before package creation; default is ${project.build.directory}/deb
• traverseExclusions - filter to exclude dependencies transitively from being processed; if dependency matches a filter it is excluded and it's transitive dependencies are not processed
  • dependencies - list of standard maven dependencies; only specified parameters are checked during filtering: specifying only a version will exclude all artifacts of that version
  • pattern - a regular expression to check artifact string (groupId:artifactId:version[:classifier]) against
• packageExclusions - filter to exclude dependencies from being processed; if dependency matches a filter it is excluded but it's transitive dependencies are still processed
  • dependencies - list of standard maven dependencies; only specified parameters are checked during filtering: specifying only a version will exclude all artifacts of that version
  • pattern - a regular expression to check artifact string (groupId:artifactId:version[:classifier]) against

data goal

Recursively copies files from a dataSourceDir to a stageDir and from controlSourceDir to controlDir.

If source directory does not exist, nothing will be copied, and plugin will finish correctly

Files are not overridden during this operation

Symbolic links are copied as is, without following them.

    <configuration>
        <dataSourceDir>${project.basedir}/src/deb/data</dataSourceDir>
        <controlSourceDir>${project.basedir}/src/deb/control</controlSourceDir>
        <stageDir>${project.build.directory}/deb</stageDir>
	<controlDir>${project.build.directory}/control</controlDir>
    </configuration>

• dataSourceDir - source directory, containing files to be included into a deb package
• controlSourceDir - source directory, containing files to be inclued into a control section of a deb packages
• stageDir - stage directory, containing files to be included into a deb package
• controlDir - stage directory, containing files to be inclued into a control section of a deb packages

copyright goal

Creates a machine-readable copyright file according to specification. May include copyright for dependencies copied into a package

Copyright information may be specified in a configuration or extracted from a pom file if no configuration present.

Copyright info is build based on a copyrightPatterns parameter and gathered from a pom file if no copyrightPatterns specified:

• copyright is constructed from a copyright symbol, inceptionYear (if present), current year and holders:
  1. project organisation, if present
  2. otherwise, project developers if present
  3. otherwise, project contributors if present
  4. otherwise user.name system property is used
• for project license mainLicence parameter is used if specified, otherwise first of project licenses is used; if no licenses present, project considered to be in a public domain.

If dependencyCopyrights parameter is set to true, all dependencies filtered by traversalExclusions and packageExclusions are grouped by their copyright and licenses and included as a separate Files paragraph. Copyright and license strings are constructed the same way as for this project

man goal

Goal generates linux man pages from markdown source. Generation process is similar to one used by ruby-ronn utility.

Goal processes every file in source directory with .md extension (case-insensitive), and converts it to a man page. Files with other extensions are silently ignored.

Each processed file must contain a level one header specifying man title, section and short description used by man-db to generate apropos database. File content before header which follows this format will be ignored

For instance, the following code will create man page with title foo in section 5 with short description bar baz qux

# foo(5) - bar baz qux
======================

Other headers in file will be turned to a sections of man file, if header of level one or two, and to a subheader for other levels.

Generation supports, lists (including nested ones), definition lists, code blocks, quotes, emphasis and other markdown feature described in commonmark markdown specification.

For further details on markdown processing see man-markdown.md

</configuration>

• manSourceDirectory - directory to read markdown files for man page generation.
  Only files with .md (case-insensitive) will be processed.
  Subdirectory structure will be preserved, with exception for .md files in directory itself. Such files will be placed to a directory named man[sectionNumber]
  Defaults to ${project.basedir}/src/deb/doc

• manDestinationDirectory - Directory to write generated man pages to.
  Subdirectory structure of source directory will be preserved, with exception for .md files in directory itself. Such files will be placed to a directory named man[sectionNumber]
  If not specified <stageDir>/usr/share/man will be used.

• deduceManTitle - Whether to try to create man title and description, if no proper heading found inside markdown file.
  Title will be deduced the following way:

  • if file name matches title.[number].md pattern, then title is used as man title, and [number] as man section
  • else if file is in directory man[number], than file name (without extension) is used as man title and, [number] as man section
  • otherwise file name (without extension) is used as title and section is assumed to be 1

  For short description required by man page specification combination of title and section name will be used

• strictManParsing - Treat parser and validation warnings as failures and abort generation.

• manSource - manual sources specified in a manual header. Package name will be used by default.

• manName - manual name specified in a manual header.

• packageName - name of debian package

• stageDir - stage directory, containing files to be included into a deb package

• sourceEncoding - encoding used to read source files

changelog goal

This goal creates and/or copies a changelog file as requested by debian policy

If copyOriginalChangelog is set to true, upstreamChangelogSource file will be gzipped and copied into changelogDestinationDirectory as changelog.gz

If convertToDebianChangelog is set, plugin will try to parse changelogSource as markdown file written according to keepachangelog.com recommendations and write a changelog in a debian format as changelog.gz or as changelog.Debian.gz if copyOriginalChangelog is also set or current version has a revision part

Details on conversion process can be found in keepachangelog-markdown.md
