set maximum heap size for maven

I am using MacBook Pro with OSX Yosemite. When I run maven clean install under my java project, I constantly get error:

java.lang.OutOfMemoryError: Java heap space

I googled a bit, and followed a suggestion to add environment variable to set bigger heap size for maven.

I edited ~/.bash_profile , added the following line:

setenv MAVEN_OPTS "-Xmx1024M -XX:MaxPermSize=512m"

and run maven clean install again, But still I got OutOfMemoryError. How could I set my maven to use maximum 1024M heap?

=== UPDATE ====

The full log :

Eventhough this is a very old thread, I think it is worth adding that the following configuration can be used when using the maven-compiler-plugin:

<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-compiler-plugin</artifactId>
     <version>3.8.1</version>
     <configuration>
          <maxmem>512m</maxmem>
     </configuration>
</plugin>

Probably the problem is in tests run by surefire plugin. You should include opts in <argLine> in surefire <configuration> tag instead of MAVEN_OPTS:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <configuration>
        <argLine>-Xmx1g -XX:MaxPermSize=256m</argLine>
    </configuration>
</plugin>
