Maven: Refer a property in pom.xml

You can access a property by using $ symbol followed by the property placed in curly braces.

Ex

<finalName>${project.groupId}-${project.artifactId}-${project.version}</finalName>

pom.xml

<project>
   <modelVersion>4.0.0</modelVersion>
   <groupId>selfLearningJava</groupId>
   <artifactId>helloworld</artifactId>
   <packaging>jar</packaging>
   <version>1</version>
   <name>helloworld</name>
   
   <build>
  <finalName>${project.groupId}-${project.artifactId}-${project.version}</finalName>
   </build>
</project>
