Java compiler plugin goes out of memory based on the comments above, to fix this you need to give Java compiler plugin more memory and to that inside your pom.xml add this

<project>
  [...]
  <build>
    [...]
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <fork>true</fork>
          <meminitial>512m</meminitial>
          <maxmem>1048m</maxmem>
        </configuration>
      </plugin>
    </plugins>
    [...]
  </build>
  [...]
</project>
