m2eclipse will not download any dependencies

Question

I was hoping someone might be able to help.

On a brand new windows machine. I've downloaded and installed java jdk before downloading and running the latest version of eclipse (indigo).

From there I have installed the maven integration plugin from the marketplace and created a new maven projected.

The project has a ton of errors mainly to do with missing dependencies or life cycle management.

When I do maven-clean I get the following error message:

[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:2.4.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-clean-plugin:jar:2.4.1: Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:2.4.1 from/to central (http://repo1.maven.org/maven2): Invalid argument: getsockname to http://repo1.maven.org/maven2/org/apache/maven/plugins/maven-clean-plugin/2.4.1/maven-clean-plugin-2.4.1.pom -> [Help 1]

I am not behind a firewall and I do not use a proxy. My maven settings.xml is completely default as is my maven project. No classes added, nothing added to the pom.

Can anyone help?

All the best.

p.s here are the errors shown in the pom:

1:

Solution

Furthermore i recommend to test the configuration etc. first with command line client of Maven (Maven 3.0.X) and not within Eclipse.

The 1./4. shows that you have tried to download some artifact which has failed for whatever reasons. The simple solution for that is to delete the local repository and retry the build. But i recommend to do that first on command line to check if everything is fine.

The 2./3. are indications that the project you are trying to compile does not contain a correct plugin coverage for m2e which can be read in the docs how to solve that.
