I am working on maven 2 project on eclipse, and I have the m2e plugin, and I am getting the following error in Eclipse:
Failure to transfer com.thoughtworks.x
If you are using Eclipse:
Go to Window->Preferences->Maven: check the download artifact source code, artifact javadoc, update maven project on startup.
Window->Preferences->Maven
In the folder that contains pom.xml, run: mvn clean install -U
mvn clean install -U
It worked for me :).
