Buils start failling

Everything was fine but suddenly all builds start falling for android:

maybe the problem is that this resource is unavailable: (https://jcenter.bintray.com/com/android/support/support-v4/maven-metadata.xml)

It crash always on the same place:

Task :app:mergeDebugResources
Task :app:mergeDebugResources FAILED

FAILURE: Build failed with an exception.

  • What went wrong:
    Execution failed for task ‘:app:mergeDebugResources’.

Could not resolve all files for configuration ‘:app:debugRuntimeClasspath’.
Could not resolve com.android.support:support-v4:26.+.
Required by:
project :app
Failed to list versions for com.android.support:support-v4.

Read timed out

It’s now working, it was a momentary error of the external inaccessible link. I only have to way.
