How to get the build version by having maven create a file with the "build.timestamp" etc. in it:

You can set it yourself by filtering a "resource" properties file that declares it, then read it as a resource, a la:

String retrieveVersionFromResource() throws IOException {
  try (InputStream br = getClass().getResourceAsStream("/auto-version.txt")) { // maven pom.xml specifies to setup auto-version.txt with some values for us
 Properties props = new Properties();
    props.load(br);
    return "build_version=" + props.get("project_version") + " " + props.get("build_date");
  }
}

where a file src/main/resources/auto-filtered of name "auto-version.txt" or "auto-version.props" or whatever you want to call it, exists

in the pom build section:


        <resources>
            <resource>
                <directory>src/main/resources-filtered
                </directory> <!-- to get "current version" into resource properties file -->
                <filtering>true</filtering>
            </resource>
            <resource>
                <directory>src/main/resources</directory> <!-- apparently have to call it out now? lame -->
            </resource>
        </resources>


contents (spring boot style project) would be:

build_date=@maven.build.timestamp@
project_version=@project.version@
contents (non springboot style):

build_date=${maven.build.timestamp}
project_version=${project.version}
