In order to update the placeholder values inside the pom file, then it can be done by below two commands

 mvn versions:set -DnewVersion="2.1.1"
 mvn versions:commit

Once done, you can trigger the build using the usual commands mvn package or mvn install

You can put properties in the pom.xml of your top-level project as such:

<project>
  <!-- other stuff ... -->
  <properties>
    <downloadSources>true</downloadSources>
    <downloadJavadocs>true</downloadJavadocs>
    <jdo.version>3.0</jdo.version>
    <datanucleus.version>2.2.1</datanucleus.version>
  </properties>
  ...
</project>

Then in your module pom.xml you can use a variable reference that will be replaced with the actual value. For example:

<dependency>
  <groupId>org.datanucleus</groupId>
  <artifactId>datanucleus-core</artifactId>
  <version>${datanucleus.version}</version>
</dependency>
