How do I add time-stamp information to Maven artifacts?
If you need the time in a timezone other than UTC (the default when you use ${maven.build.timestamp}
) you could use the build-helper-maven-plugin
. See more in Brief examples on how to use the Build Helper Maven Plugin's goals.
Anyway, this is how I've got the timestamp in GMT-5 and put it in the final name of my artifact:
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>build-helper-maven-plugin</artifactId>
<version>1.9.1</version>
<executions>
<execution>
<id>timestamp-property</id>
<goals>
<goal>timestamp-property</goal>
</goals>
<configuration>
<name>current.time</name>
<pattern>yyyyMMdd-HHmmss</pattern>
<timeZone>GMT-5</timeZone>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<finalName>${project.name}-${current.time}</finalName>
</configuration>
</plugin>
</plugins>
</build>
Maven versions 2.1.0-M1 or newer have built in special variable maven.build.timestamp
.
<build>
<finalName>${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>
These three sites are also worth checking out.
If you use a version of Maven >= 2.1.0-M1, then you can use the ${maven.build.timestamp} property.

This post (especially the below part) is also very useful and practical for this issue.
Stamping Version Number and Build Time in a Properties File with Maven
The pom will look like this
...
<properties>
....
<!-- Timestamp of build -->
<timestamp>${maven.build.timestamp}</timestamp>
<maven.build.timestamp.format>yyyy_MM_dd_HH_mm</maven.build.timestamp.format>
</properties>
...
<build>
<finalName>${project.artifactId}-${project.version}-${timestamp}</finalName>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
....
</plugin>
</plugins>
</build>
....
and the package name is MyProject-1.0.0-2015_03_02_13_46.war
