Answer 1

You're missing the trailing letter s in groupId of the plugin. Correct declaration should be:

<dependency>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-release-plugin</artifactId>
    <version>2.1</version>
</dependency>

I'd also consider upgrading to a fresher version. As far as I can see, current version is 2.4.1.
