releasing

1. checkout 1.0-SNAPSHOT

   • git clone

2. update POM version to 1.0-RELEASE

   • mvn versions:set -DnewVersion=

   • mvn versions:update-properties -Dincludes=com.example:*

3. compile, test

   • mvn clean test

   • docker build

4. commit, tag, publish, deploy

   • commit

   • mvn scm:tag -DVERSION_NUMBER=${BUILD_NUMBER}

   • publish

     • mvn deploy

     • docker push

   • install, or docker push

5. update POM to 2.0-SNAPSHOT

   • versions:set -DnewVersion=

6. commit

Plugins

Below are most relevant for deployment purposes.
Full list is available under: https://maven.apache.org/plugins/index.html

Build-Helper plugin

http://www.mojohaus.org/build-helper-maven-plugin/parse-version-mojo.html

build-helper:parse-version

Parses POM to find versions and sets properties:

Current version properties:

• parsedVersion.majorVersion

• parsedVersion.minorVersion

• parsedVersion.incrementalVersion

• parsedVersion.qualifier

• parsedVersion.buildNumber

Next version properties:

• parsedVersion.nextMajorVersion

• parsedVersion.nextMinorVersion

• parsedVersion.nextIncrementalVersion

• parsedVersion.nextBuildNumber

Versions plugin

http://www.mojohaus.org/versions-maven-plugin/usage.html
Use -DgenerateBackupPoms=false in command line or plugin configuration to avoid backup POMs generation.

Goals with no modifications

• mvn versions:display-dependency-updates deep dependency update candidates

• mvn versions:display-property-updates

Goals with modifications

• mvn versions:set -DnewVersion=2.1.0-SNAPSHOT -DgenerateBackupPoms=false

• mvn versions:use-latest-releases - update dependencies

• mvn versions:update-parent

• mvn versions:update-properties -Dincludes=com:* -DgenerateBackupPoms=false - update properties which are used as dependency versions

• mvn versions:lock-snapshots, mvn versions:unlock-snapshots

Revert/Commit

• mvn versions:revert

• mvn versions:commit

---

Release plugin

Use --batch-mode for non-interactive mode. fro example mvn release:update-versions --batch-mode

Process

• no SNAPSHOTs

• Change the version in the POMs from x-SNAPSHOT to a new version

• Run the project tests

• Commit the modified POMs

• Bump the version in the POMs to a new value y-SNAPSHOT

• Commit the modified POMs

Tasks

• mvn release:clean Clean up after a release preparation.

• mvn release:prepare Prepare for a release in SCM.

• mvn release:perform Perform a release from SCM.

• mvn release:update-versions Update the versions in the POM(s).

SCM plugin

Task which may be useful for releasing: mvn scm:tag
Use -DpushChanges=false if push is done outside of maven.
In order to use project version as a tag:

<configuration>
    <tag>${project.version}</tag>
</configuration>

Deploy plugin

Publish artifact to artifact repository.
Add following conf for it to work:

<distributionManagement>
  <repository>
    <id>internal.repo</id>
    <url>http://repo.example.com/repository/example</url>
  </repository>
</distributionManagement>

And in settings.xml:

<server>
  <id>internal.repo</id>
  <username>maven</username>
  <password>foobar</password>
</server>

Update process

Remove SNAPSHOT

mvn build-helper:parse-version versions:set -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.minorVersion}.\${parsedVersion.nextIncrementalVersion} -DgenerateBackupPoms=false

Update release minor version

mvn build-helper:parse-version versions:set -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.nextMinorVersion}.0 -DgenerateBackupPoms=false

Update release iter version

mvn build-helper:parse-version versions:set -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.minorVersion}.\${parsedVersion.nextIncrementalVersion} -DgenerateBackupPoms=false

Update snapshot version

mvn build-helper:parse-version versions:set -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.nextMinorVersion}.0-SNAPSHOT -DgenerateBackupPoms=false
