Non-resolvable parent POM for Could not find artifact and 'parent.relativePath' points at wrong local POM

I faced the same issue. Setting relative path of the parent in module projects solved the issue.

Use <relativePath>../Parent Project Name/pom.xml</relativePath>

You need to have the file /root/test/devenv/openstack-rhel/pom.xml

This file need to have the followings elements:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <groupId>org.openstack</groupId>
    <artifactId>openstack-rhel-rpms</artifactId>
    <version>2012.1-SNAPSHOT</version>
    <packaging>pom</packaging>
</project>

I encountered an issue like this using the Maven Release Plugin. Resolving using relative paths (i.e. for the parent pom in the child module ../parent/pom.xml) did not seem to work in this scenario, it keeps looking for the released parent pom in the Nexus repository. Moving the parent pom to the parent folder of the module resolved this.
