I am new to Apache beam, I download latest source code from github and compile runner module under path :
../beam/runners
with command : mvn package and it prints the exception like this :

Here are my compile steps:
cd beam-master
mvn compile
wait compile finish
The first time I execute mvn compile command and met the exception shown above was under path beam-master/runners. After I changing compiling path to beam-master everything goes well .
And may I ask are you trying to compile the whole project to load it to your IDE ?
If so , I suggest using IDEA with 'File'->'import from existing source' instead of executing 'mvn compile' command .
If you try to use IDEA import beam , you can just remove/comment error messages in ${project_loc:beam-parent/pom.xml} like ：
<!-- <plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>versions-maven-plugin</artifactId>
<version>2.3</version>
<reportSets>
<reportSet>
<reports>
<report>dependency-updates-report</report>
<report>plugin-updates-report</report>
</reports>
</reportSet>
</reportSets>
</plugin>-->
and, replace this maven plugins version the same as your mvn -version .
<!-- Rename the artifact produced by the Apache parent's
source release. -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-assembly-plugin</artifactId>
<version>**3.3.3**</version>
<executions>
<execution>
<id>source-release-assembly</id>
<configuration>
<finalName>apache-beam-${project.version}</finalName>
</configuration>
</execution>
</executions>
</plugin>
By the way , my maven version is 3.3.3 . You can also check out if the pom.xml's maven version incompatible with your local mvn -version .
Here is my mvn compile path :

After I changing my compiling path to main path every module compiled success.
