You probably use Maven 3 which need to know all plugins versions as describe here : https://cwiki.apache.org/confluence/display/MAVEN/Maven+3.x+Compatibility+Notes#Maven3.xCompatibilityNotes-AutomaticPluginVersionResolution

Adding in the pluginManagement section of your parent pom.xml all plugins versions is the right way. The best way (in enterprise) is to have an enterprise parent pom.xml file used by all projects.

In fact, add the following line in your parent pom.xml properties section :

<maven-compiler-plugin.version>3.0</maven-compiler-plugin.version>

And add the following line in your parent pom.xml build > pluginManagement section :

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>${maven-compiler-plugin.version}</version>
</plugin>

Hope it helps...
