Karl Heinz Marbaise commented on MNG-6438:
------------------------------------------
If you change your pom file like this:
{code:xml}
<?xml version="1.0" encoding="UTF-8"?>
<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/maven-v4_0_0.xsd";>
<modelVersion>4.0.0</modelVersion>
<parent>
<groupId>whateverGroup</groupId>
<artifactId>artifact</artifactId>
<version>4.0.0</version> <!-- Fixed version needed. -->
</parent>
<artifactId>root</artifactId>
<version>${sha1}</version>
</project>
{code}
Than it will work. The intention was to have a version which can changed by
properties inside the reactor not always which mean in this case not for the
parent...
