How to pass the pom version to the code

To replace the artifact version in a class during the build process, you can use the below plugin:

<plugin>
	<groupId>com.google.code.maven-replacer-plugin</groupId>
	<artifactId>replacer</artifactId>
	<version>1.5.3</version>
	<executions>
		<execution>
			<phase>process-sources</phase>
			<goals>
				<goal>replace</goal>
			</goals>
		</execution>
	</executions>
	<configuration>
		<ignoreMissingFile>false</ignoreMissingFile>
		<file>${project.build.sourceDirectory}/path/to/Version.java.template</file>
		<outputFile>${project.build.sourceDirectory}/path/to/Version.java</outputFile>
		<regex>false</regex>
		<token>@version@</token>
		<value>${project.version}</value>
	</configuration>
</plugin>

where Version.java.template:

public class Version {
	private Version() {
		// don't instantiate
	}

	public static String id() {
		return "@version@";
	}
	
	public static void main(String[] args) {
		System.out.println(id());
	}
}
