Hi,
You parent pom is like any artifact and you have to indicate to maven 2
where to find it.
Since you have a corporate repository (via a maven proxy) you have two
solutions :
1. Either you add a reference to your corporate repository in your pom.xml
<repositories>
<repository>
<id>inhouse</id>
<name>Inhouse maven repository</name>
<url>url to your corporate repository</url>
<releases>
<enabled>true</enabled>
</releases>
<snapshots>
<enabled>false</enabled>
</snapshots>
</repository>
2. or by specifying your corporate repository to maven 2 in your setting.xml
<mirrors>
<mirror>
<id>Corporate Proxy</id>
<mirrorOf>central</mirrorOf>
<name>my corporate repository</name>
<url>url to your corporate repository</url>
</mirror>
It's important to use the token central for the node mirrorOf.
In general, the second solution is better when using a maven 2 proxy.
HTH,
