There're two advantages for adding an Eclipse configuration:

• The coding style can be shared and using across a team use Eclipse, Intellij and Netbeans.
• Intellij doesn't play well with non-javadoc comment. But in practice, we need that kind of comments to explain the background behind the code, something that helpful for maintainer, but can not be put into Javadoc. Eclipse Formatter handle this very well.

Known issues:

• There're no porting version for SquareAndroid.xml, as I don't think it's necessary.
• Line breaks between annotation and method is not kept.

// input
interface HttpBinService {
  @GET("/ip")
  MyCall<Ip> getIp();
}

// Intellij won't change it. But Eclipse Formatter will remove the line break.
interface HttpBinService {
  @GET("/ip") MyCall<Ip> getIp();
}
