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.

  • the dependencies are listed in my project , but when I open http://repo1.maven.org there was a message "Browsing for this directory has been disabled."..so how can I fix this then? – Prajyod Kumar Aug 11 '14 at 12:39
  • @PrajyodKumar: Read the rest of the text. – Aaron Digulla Aug 11 '14 at 13:23
  • To fix the problem with Gradle, you need to configure it to use the same proxy settings as your web browser. – Aaron Digulla Aug 11 '14 at 13:25
  • I have same problem. I can access google.com normally but can not access repo1.maven.org. Not meaning can not access. The message is "Browsing for this directory has been disabled...." – Bulma Jul 24 '15 at 07:15
  • @KouTokyo: Maven Central doesn't allow to access this URL with a browser. But when you get the error page, that means your browser could connect to Maven Central - so the firewall is OK. – Aaron Digulla Jul 24 '15 at 11:06

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

In my case the problem was resolved when I changed my gradle version from 4.6 to 4.7.

@Aaron Digulla said I have firewall problem.

I was having problem with GSON dependency, (hope it will solve other dependecy problems also) and this answer solved the problem. Stack Overflow Could not resolve all dependencies for configuration ':classpath'

@Kangars post : This is what i have in my gradle.build for build script and allprojects

buildscript {
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

allprojects {
repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
  }
}

This is because of slow internet connection or you haven't configure proxy settings correctly. Gradle needs to download some dependencies , if it cant access the repository it fires this error. All you have to do is check your internet connection and make sure gradle can access the maven repository.

The root cause Connection to http://repo1.maven.org refused indicates that the build is failing as gradle is not able to fetch some dependencies from the repository.

Here is a list of causes and corresponding resolutions you might want to try:

  1. Internet connectivity issues - Have a good internet speed and connectivity
  2. Firewall (system or third party) - Ensure firewall is not blocking access to the repository
  3. Working behind a proxy - Gradle proxy configuration
  4. Firewall or some random application meddling with proxy application1 - Kill the process meddling with the proxy application
  5. The proxy application causes certificate problems2 - Import proxy application's certificate

It looks like you don't have a working internet connection or haven't configured your proxy/firewall. Please check if you can access repo1.maven.org from commandline or a browser.

I used the steps below to fix it.

  1. Go to command prompt and set the java opts.

    SET JAVA_OPTS=-Dhttp.proxyHost=your_proxy_server_name -Dhttp.proxyPort=your_proxy_port -Dhttp.nonProxyHosts=127.0.0.1

  2. Then build your Gradle application and all the connection refused errors no longer appear.

    gradle clean build distZip

Mine worked after turning on the VPN. Although the build seems to take a long time and seems to stall at 85%, the service is actually building and I'm able to load it

For my case it was a poor connection issue so the IDE couldn't get resources online
