Fix for Build Failure due to missing eclipselink 2.3.1 in central maven

[V.A, Chandan]

Hello All
In order to fix the build failure that is arising due to missing eclipse link 
jar:2.3.1 in central maven, I would like to add the following section to parent 
pom.xml

<repositories>
<repository> <!-- not just for eclipse link but in general -->
                <id>oss.sonatype.org</id>
                <name>OSS Sonatype Staging</name>
                <url>https://oss.sonatype.org/content/groups/staging</url>
</repository>
<repository> <!-For Eclipse Link prior to 2.4.2 -->
   <id>EclipseLink</id>
   <url>http://download.eclipse.org/rt/eclipselink/maven.repo</url>
</repository>
</repositories>

As explained in section "Repositories" - 
http://wiki.eclipse.org/EclipseLink/Maven

Is this fine?

Thanks,
Kind Regards
Chandan VA
