I was trying to build an Android app, but I got the above error. When I connect to “https://jcenter.bintray.com/com/google/http-client/google-http-client-android/maven-metadata.xml”, an nginx 403 error appears. Is JCenter down? What should I do?

CodePudding user response：

Yes, you are not alone. Jcenter seems down today.

My solution is change all the jCenter to mavenCentral from root/android/build.gradle

Also, don't forget the libraies node_module/*error libaray*/android/build.gradle

CodePudding user response：

I just meet this problem as well, I'm not quite sure why jcenter returns 403, but you can fix this problem by add mavenCentral() before jcenter() in repositories setting, like this:

    repositories {
        ...
        mavenCentral() // add this line
        jcenter()
        ...
    }

CodePudding user response：

I think mavenCentral is not the complete alternative to jcenter.
I'm using aliyun's mirror. replace jcenter() with maven { url "https://maven.aliyun.com/repository/jcenter" }.

Don't know if its accessible from outside of china, or does aliyun censorship some packages, or is it up to date.

CodePudding user response：

as a temperary measure, you can use mirror site

I solved it this way

allprojects {
    repositories {
        // Jcenter mirror
        maven { url "https://maven.aliyun.com/repository/jcenter" }
        // other repo
    }
}
