How to have Maven show local timezone in maven.build.timestamp?

Question

In Maven 3.2.2+, the maven.build.timestamp has been redefined to show the time in UTC, as per MNG-5452.

Is there any way to specify that I want the timezone info in my local timezone and not in UTC? I briefly browsed the maven sources, but do not see anyway to specify that I want the TZ to be local TZ and not UTC based.

As already mentioned, in the current versions of Maven (at least up to version 3.3.+), the maven.build.timestamp property does not allow for timezone overrides.

However, if you are okay with utilizing a different property name for your purposes, the build-helper-maven-plugin allows you to configure custom timestamps for a variety of purposes. Here is an example to configure the current timestamp in EST during a build.

        <plugin>             <groupId>org.codehaus.mojo</groupId>             <artifactId>build-helper-maven-plugin</artifactId>             <version>1.10</version>             <executions>                 <execution>                     <id>timestamp-property</id>                     <goals>                         <goal>timestamp-property</goal>                     </goals>                     <configuration>                         <name>build.time</name>                         <pattern>MM/dd/yyyy hh:mm aa</pattern>                         <locale>en_US</locale>                         <timeZone>America/Detroit</timeZone>                     </configuration>                 </execution>             </executions>         </plugin> 

Then you can utilize the ${build.time} property instead of ${maven.build.timestamp} where you need a timestamp of the build in your preferred timezone.
