Cannot Upgrade To Latest Support Library Android Studio

I have installed the latest version of Android Support Repository (47.0.0), but I can't build my project because of the following error. ERROR Here is my build.gardle code compile

Solution 1:

Check your build.gradle. You should have google repo:

allprojects {
    repositories {
        google()
        jcenter()
    }
}

Solution 2:

It was a proxy issue after all.I had to replace the default lines in gradle.properties with this line:

org.gradle.jvmargs=-DsocksProxyHost=127.0.0.1 -DsocksProxyPort=9090

It took me a week to find it out.thanks to those who answered or commented and tried to help.

Solution 3:

From the error none of the libraries can be resolved. So I think the problem is with your maven not being able to get access to the repositories. This can be because of bad internet or not being configured correctly.

I would check the maven repository configurations:

allprojects {
    repositories {
        jcenter()
        mavenLocal()

or

try this:

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