Maven Could not resolve dependencies, artifacts could not be resolved

mvn clean install -U

Solved my problem. Since the repos were cached, I needed to force it to get latest version.

Looks like you are missing some Maven repos. Ask for your friend's .m2/settings.xml, and you'll probably want to update the POM to include the repositories there.

--edit: after some quick googling, try adding this to your POM:

<repository>
    <id>com.springsource.repository.bundles.release</id>
    <name>SpringSource Enterprise Bundle Repository - SpringSource Bundle Releases</name>
    <url>http://repository.springsource.com/maven/bundles/release</url>
</repository>
<repository>
    <id>com.springsource.repository.bundles.external</id>
    <name>SpringSource Enterprise Bundle Repository - External Bundle Releases</name>
    <url>http://repository.springsource.com/maven/bundles/external</url>
</repository>

Maven kept your files on cache, and don't retry to download them. You can simply manually 'help' him by deleting the .m2 directory, and then our friend will download everything over the old dependencies.
