What does this mean: Not a v4.0.0 POM. for project org.codehaus.mojo:rpm-maven-plugin

Question

I'm afraid I just don't know what this error means, besides that there is an error. I was able to build jars before, but this is my first time using the rpm-maven-plugin.

I would like to create an rpm, but so far using the rpm-maven-plugin has resulted in errors.

Answer 1

The problem was exactly as the error stated. I went to my respository and opened the POM file at the path above. I realize that somehow the POM file was downloaded while I was not authenticated against one of our internal systems.

So even though a file existed, the pom file only contained an error message.

After deleting the file at the path and restarting the build, the build was successful.

Answer 2

I found that I was missing the ~/.m2/settings.xml file. Once I got that file, I was able to use maven just fine.
