Hi,

I have test project where i defined the pom like this:

...
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.soebes.examples.j2ee</groupId>
  <artifactId>parent</artifactId>
  <version>${revision}</version>
  <packaging>pom</packaging>

If i define the revision on command line like this.

mvn -Drevision=1.0-SNAPSHOT clean package

everything fine...

But now i want to make the usage a bit more convenient so i added the following to my pom:


  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <revision>1.0-SNAPSHOT</revision>
  </properties>

to have a default for revision which works fine now...

But if i would like to overwrite the property from command line like this:

mvn -Drevision=1.0 clean package

the build failes in the following location:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.5.5:single (assemblies) on project assembly: Failed to create assembly: Unable to resolve dependencies for assembly 'archive': Failed to resolve dependencies for assembly: Unable to get dependency information for com.soebes.examples.j2ee:service-client:jar:1.0-SNAPSHOT: Failed to process POM for com.soebes.examples.j2ee:service-client:jar:1.0-SNAPSHOT: Non-resolvable parent POM for com.soebes.examples.j2ee:service-client:[unknown-version]: Failure to find com.soebes.examples.j2ee:parent:pom:${revision} in http://localhost:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced
[ERROR] com.soebes.examples.j2ee:service-client:jar:1.0-SNAPSHOT

The project is available on github (https://github.com/khmarbaise/javaee/tree/mvn321)....

So the question which is coming up...is this based on Maven core or is this based on maven-assembly-plugin ?

Kind regards
Karl Heinz Marbaise
