Problem with maven-antrun-plugin task being run with the jre rather than the jdk

[Orion Poplawski]

seem to be facing a classic issue with a maven-antrun-plugin task being run 
with the jre rather than the jdk and not finding the compiler.  Haven't yet 
found the proper fix though.  Any ideas?

[ERROR] Failed to execute goal 
org.apache.maven.plugins:maven-antrun-plugin:1.7:run (rdt-remote-jars) on 
project org.eclipse.ptp.rdt.core.remotejars: An Ant BuildException has

Java compiler is in tools.jar, you need to add it to classpath of antrun plugin
explicitly, for example:

<plugins>
  <plugin>
    <artifactId>maven-antrun-plugin</artifactId>
    [...]
    <dependencies>
      <dependency>
        <groupId>com.sun</groupId>
        <artifactId>tools</artifactId>
        <version>1.7</version>
        <scope>system</scope>
        <systemPath>${java.home}/../lib/tools.jar</systemPath>
      </dependency>
    </dependencies>
  </plugin>
</plugins>

That's already there, although perhaps not in the right place?  See attached 
pom.xml.  Or maybe because the version is too old?

That mapping is in a profile which only gets activated with Sun JDK. This is
wrong. Moving the dependency into proper build/plugins section should solve the
issue. I am not entirely sure why upstream decided to put it into profile. Maybe
something to do with macs? Maybe some fix could be upstreamed too...

Thanks, I've moved it down into the build/plugins section and it works there. 
I've pinged upstream about it.
