Androidstudio 1.4 After upgrading to 1.5, peer not authenticated error

Workaround:

Find the outermost build.gradle file of the project, which will include:

dependencies {
Classpath ' com.android.tools.build:gradle:1.2.3 '
}

Modified to:

dependencies {    ' com.android.tools.build:gradle:1.3.0 '}

It's all right!

If not, you can change the Jcenter () in this file to:

Jcenter {
URL "http://jcenter.bintray.com/"
}

Add: If you want to modify the version of Gradle in the project, it is not possible to see the following:

In the project settings:

You can see that this version is the version of the project build, which corresponds to the wrapper under the project root Gradle folder:

Summary: If you modify the Gradle version, you can change the settings directly in the project, and the wrapper in the root directory will be verified.
