maven git commit id plugin

Build Status Coverage Status Maven Central

git-commit-id-maven-plugin is a plugin quite similar to Build Number Maven Plugin for example but as the Build Number plugin at the time when I started this plugin only supported CVS and SVN, something had to be done. I had to quickly develop a Git version of such a plugin. For those who don't know the plugin, it basically helps you with the following tasks and answers related questions

  • Which version had the bug? Is that deployed already?
  • Make your distributed deployment aware of versions
  • Validate if properties are set as expected

If you are more interested in the different use-cases, feel free to read about them in more detail.

Quicklinks (all relevant documentation)

Getting the plugin

The plugin is available from Maven Central (see here), so you don't have to configure any additional repositories to use this plugin.

A detailed description of using the plugin is available in the Using the plugin document. All you need to do in the basic setup is to include that plugin definition in your pom.xml. For more advanced users we also prepared a guide to provide a brief overview of the more advanced configurations... read on!

Relocation of the Project

Newer version (5.x.x or more recent) are available via

<groupId>io.github.git-commit-id</groupId>

Versions

The current version is 5.0.0 (changelist).

You can check the available versions by visiting search.maven.org, though using the newest is obviously the best choice.

Plugin compatibility with Java

Here is an overview of the current plugin compatibility with Java

Plugin Version Required Java Version
2.1.X Java 1.6
2.2.X Java 1.7
3.0.0 Java 1.8
4.0.0 Java 1.8
5.0.0 Java 11

Plugin compatibility with Maven

Even though this plugin tries to be compatible with every Maven version there are some known limitations with specific versions. Here is a list that tries to outline the current state of the art:

Maven Version Plugin Version Notes
Maven 3.0.X (EOL) up to 4.0.5 Maven 3.0.X is EOL
Maven 3.1.0 any git-commit-id-plugin:2.1.14, 2.1.15, 2.2.0, 2.2.1, 2.2.3 doesn't work -- requires maven version 3.1.1
Maven 3.3.1 any git-commit-id-plugin:2.1.14 doesn't work
Maven 3.3.3 any git-commit-id-plugin:2.1.14 doesn't work
Maven 3.X.X (3.0.X is EOL) any Any other non listed version here should work with any plugin version

Note: As an example -- this table should be read as: For Maven 3.1.0 any Plugin Version should work, besides the ones listed in the Notes have the limitations listed.

Plugin compatibility with EOL Maven version

End of life (EOL) Maven versions are no longer supported by Maven, nor this plugin. The following information is made available for reference.

Maven Version Plugin Version Notes
Maven 2.0.11 up to 2.2.6 Maven 2 is EOL, git-commit-id-plugin:1.0 doesn't work -- requires maven version 2.2.1
Maven 2.2.1 up to 2.2.6 Maven 2 is EOL
Maven 3.0.X up to 4.0.5 git-commit-id-plugin:2.1.14, 2.1.15, 2.2.0, 2.2.1, 2.2.3 doesn't work -- requires maven version 3.1.1
Maven 3.0.X up to 4.0.5 For git-commit-id-plugin 2.2.4 or higher: works, but failed to load class "org.slf4j.impl.StaticLoggerBinder"

Getting SNAPSHOT versions of the plugin

If you really want to use snapshots, here's the repository they are deployed to. But I highly recommend using only stable versions, from Maven Central... :-)

<pluginRepositories>
    <pluginRepository>
        <id>sonatype-snapshots</id>
        <name>Sonatype Snapshots</name>
        <url>https://s01.oss.sonatype.org/content/repositories/snapshots/</url>
    </pluginRepository>
</pluginRepositories>

Older Snapshots (prior version 5.X) are available via <url>https://oss.sonatype.org/content/repositories/snapshots/</url>.

If you just would like to see what the plugin can do, you can clone the repository and run

mvn clean install -Dmaven.test.skip=true && mvn clean package -Pdemo -Dmaven.test.skip=true
