Answer 1

The real error is this:

Connection to http://repo1.maven.org refused

Gradle needs to download the dependencies listed in the error message to be able to compile the project.

You're probably behind a firewall or your Internet connection isn't working. You need to make sure Gradle can access http://repo1.maven.org.

Note: Maven Central (http://repo1.maven.org) can be accessed with a browser. If you see the message "Browsing for this directory has been disabled" that means your browser could connect to the server (the error is a special message my Maven Central, not a standard HTTP error message).

If you see this but Maven or Gradle fail, then you need to check your browser's/OS's proxy settings and configure your tool accordingly.

Using --refresh-dependencies switch with gradle, helped me to resolve this issue.
