Answer 1

The reason you're getting this error is because you're trying to build with the release-central profile in Maven. You are not allowed to do this, you can remove the profile from your build configuration.

So if you have something like:

mvn clean install -Prelease-central

.. then that won't work.

In general, you should just load the dd4t dependencies as real dependencies and not as source code. This will make things a lot easier and clear. Please see the quickstart guide and the wiki for more information.

Update

From the comments I see that you are loading in the archetype as module. This is also not possible. What you get then is the source to generate an archetype package, which then generates a base project based on parameters. If you want to use the archetype, the only way to do that is by doing:

mvn archetype:generate -DgroupId=[com.example] -DartifactId=[mywebapp] -DarchetypeGroupId=org.dd4t -DarchetypeArtifactId=dd4t-spring-mvc-archetype -DarchetypeVersion=1.5  -DarchetypeCatalog=remote -DarchetypeCatalog=http://repo1.maven.org/maven2

Only if you want to change the archetype's source, you'd need gpg locally. You can follow SonaType's guide on how to do that.
