Gradle ProjectName Project Update Error - Error: already seen Doctype

Question

I'll go crazy! I already searched and tried everything (google and stackoverflow), but nothing helps.

I am trying to open (also tried to import) a slidenerd project on Github ( http://github.com/slidenerd/materialtest ) in Android Studio 1.2.1.1 with Gradle 2.2, but I got this annoying error!

Gradle Failed to update ProjectName project

Error: already seen Doctype

Can you help me understand what I can do to solve it?

This is my Gradle console log:

Accomplishment of tasks: [:]

On-demand configuration is an incubation function. Download https://jcenter.bintray.com/com/android/tools/lint/lint/24.0.1/lint-24.0.1.pom

Answer 1

This happened to me when I had two google and gradle:3.0.0 repositories as dependencies in the build.gradle file:

 allprojects { repositories { google() jcenter() maven { url "https://maven.google.com" } } } dependencies { classpath 'com.android.tools.build:gradle:3.0.0' } 

It was an obvious mistake. So I removed the maven part and changed com.android.tools.build:gradle:3.0.0 to com.android.tools.build:gradle:3.0.1 .

This solved my problem.

Answer 2

network may be the cause. I changed my vpn network and then gradle was successful.

Answer 3

Make sure that the build.gradle (project) file uses only jcenter () as the repository resource, not maven or mavenCentral.
