React-native-contacts: Could not find com.android.tools.build:gradle:2.3.1

Getting the below error since yesterday while generating build at App Center.
But it is not mentioned in my gradle file

Build.gradle

 dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

Error:

I have the same error, any leads ?

[sakymar]

found this :

subprojects { project ->
def name = project.name
if (name.contains('react-native-contacts')) {
    buildscript {
        repositories {
            maven { url "https://dl.bintray.com/android/android-tools/"  }
        }
    }
} } 

to add in the build.gradle

[kashishgrover]

From what I have been able to figure, this is happening for a lot of libraries right now.
If you notice on com.android.tools.build on maven.google.com, they seem to have removed Gradle jars lower than v3.0.0.

I am facing the same issue with react-native-linear-gradient v2.4.0 and also my project as a whole which is currently on RN 0.52 with Gradle v2.2.3.

In the manner you mentioned above, right now I am adding maven { url 'http://repo.spring.io/plugins-release' } for all the dependencies which seem to be on older Gradle versions since this URL still serves those. Let's see if this fixes the problem. Will update here.

[kashishgrover]

Yup, this fixed it. Add this to your project's build.gradle

buildscript { . . .

allprojects { . . . 

subprojects { project ->
    def name = project.name
    if (name.contains('react-native-contacts') ||
            name.contains('react-native-svg') ||
            name.contains('react-native-linear-gradient') ||
            name.contains('react-native-shimmer')
    ) {
        buildscript {
            repositories {
                maven { url 'http://repo.spring.io/plugins-release' }
            }
        }
    }
}

@kashishgrover is there a way to write PR so this is fixed for users of this module? should the readme instruct to add that to gradle?

[raghavendramogeraya]

This issue is resolved now, as the repositories are back now.

[kashishgrover]

@morenoh149 I don't think there can ever be a permanent fix for such things. In this case randomly the repos disappeared from jcenter which should not have happened. Meanwhile as a check I did add the above code to my project. I think leaving that to the user makes more sense.

[morenoh149]

@kashishgrover I thought it was an issue with google updating the gradle version being used. And thus the older dependency was deleted from the location. We merged this update https://github.com/rt2zz/react-native-contacts/commit/62bafa5dbd181b01f45f9d56b2bbec88218fe8af which may be why things are working now?
