How do I add time-stamp information to Maven artifacts?

Question

Maven versions 2.1.0-M1 or newer have built in special variable maven.build.timestamp.

<build>
  <finalName>${project.artifactId}-${project.version}-${maven.build.timestamp}</finalName>
</build>

See Maven documentation for more details.

For older Maven versions a look at maven-timestamp-plugin or buildnumber-maven-plugin.

If you use maven-timestamp-plugin, you can use something like this to manipulate resulting artifact name.

<build>
   <finalName>${project.artifactId}-${project.version}-${timestamp}</finalName>
</build>

And this configuration for buildnumber-maven-plugin should create a ${timestamp} property which contains the timestamp value. There doesn’t seem to be a way to create the version.properties file directly with this plugin.

<configuration>
   <format>{0,date,yyyyMMddHHmmss}</format>
   <items>
      <item>timestamp</item>
   </items>

</configuration>
