<properties>
  <buildDate>${build.timestamp}</buildDate>
</properties>

Output:

2021-09-22T08:38:51,295 INFO : [main] - Application - loaded version.properties: {app.buildDate=2021-09-22T06:38:13Z, app.version=v1.0.0}

sorry for unformatted code, I can't change that :(

it should work as expected - there i an IT covering the behavior and evaluating the result: https://github.com/mojohaus/build-helper-maven-plugin/tree/master/src/it/timestamp-regex

please run your maven build with debug output (-X) and check for a line including "define property" and your property, this should print the value the plugin has actually set.
