Maven eclipse error: "Archive for required library cannot be read or is not a valid ZIP file"

I got the "Archive for required library cannot be read or is not a valid ZIP file" error for my maven project I imported in Eclipse. I read some posts about this and suggested is to delete the faulty directory like in my case:
~.m2\repository\com\cogentex\rpw\2.2 and
~.m2\repository\com\cogentex\rpw-lkb\2.2
Then you should update the project via Eclipse: Maven>Update project and click force update of snapshots/releases. I followed these steps and the directory looks like this now:

So the correct .jar files are still missing and it also results in more erorrs now:
1: Missing artifact com.cogentex:rpw-lkb:jar:2.2
2: Missing artifact com.cogentex:rpw:jar:2.2
3: The container 'Maven Dependencies' references non existing library '~.m2\repository\com\cogentex\rpw\2.2\rpw-2.2.jar'

Here is the snippet from the pom.xml which throws the first two errors:

    <dependency>
        <groupId>com.cogentex</groupId>
        <artifactId>rpw</artifactId>
        <version>2.2</version>
    </dependency>

    <dependency>
        <groupId>com.cogentex</groupId>
        <artifactId>rpw-lkb</artifactId>
        <version>2.2</version>
    </dependency>

What do I have to do to make maven download the correct .jar files? I already tried running maven cleanor maven install and restarting Eclipse.

What you see in the folder is some files that indicate the artifact was not found and when was the last time Maven checked.

Whatever com.cogentex:rpw is, it's not in Maven Central so Maven will not find it there. You need to tell Maven where to get it from by providing the URL to a repository that contains it. If/when your POM has the repository, make sure

  • you do have access to the reposiory from the environment you run your build in (check proxies, firewalls, ...)
  • the GAV coordinates (groupId, artifactId, version) are correct and match the one in the repository.
  • the artifact type in the repository is jar. If it is not, provide the correct type in the dependency
  • the artifact is not deployed to the repository with classifier. If it is, provide the classifier in the dependency
