Android Gradle Sync failed could not find support-core-ui.aar

Question

I've been working on this Android Project for about a year now, suddenly when I opened it yesterday Android Studio 3.1.2 failed to sync gradle and the project doesn't build anymore giving me this error:

Could not find support-core-ui.jar (com.android.support:support-core-ui:27.1.1).
    Searched in the following locations:
        https://jcenter.bintray.com/com/android/support/support-core-ui/27.1.1/support-core-ui-27.1.1.jar

    Please install the Android Support Repository from the Android SDK Manager.
    Open Android SDK Manager

I'm pretty sure that the Android Support Repository is installed correctly because it's working successfully in other projects and all my other projects are working fine with no problems.

I have this gradle file in the app module:

Any suggestions or solutions are very appreciated. Thanks.

Answer 1

OK, so that's why:

AAPT2 now on Google's Maven repo: To use AAPT2, you must add Google's Maven repository to your project-level build.gradle, as shown below. Learn more

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

Answer 2

I just resolved this problem on my own build server. I updated my repositories block in my build.gradle to have google() as the first entry like below:

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

Edit: removed a repo that was not needed.

Answer 3

I added google() in my build.gradle

buildscript {
    repositories {
        jcenter()
        google()
        mavenLocal()
        maven { url 'https://maven.google.com'  }
    }
}

allprojects {
    repositories {
        jcenter()
        google()
        mavenLocal()
        maven { url 'https://maven.google.com'  }
    }
}

for me it fixed the problem. You can try it too.

Answer 4

Switch from

    jcenter()
    google()

to

    google()
    jcenter()

Answer 5

So I've been able to solve the problem, but maybe just a workaround so at least my CI build passes. It appears that including this line in my gradle dependencies fixed it:

implementation "com.android.support:support-core-utils:27.1.1"

Also I made sure google() is the first one listed in my top-level gradle repository

Answer 6

I had this exact problem, realizing I also updated my gradle to 4.8 between my last successful build and the now broken ones. I downgraded back for 4.7 and my continuous integration builds work again.

Answer 7

1. Check if you are working offline.

   File > Settings > Write "offline" on the search bar > Gradle > uncheck "offline work".

2. Use the keyword "implementation" instead of "compile". Compile is deprecated and will be abandoned by the end of 2018. This is a long shot, but something might have changed since the last Android Studio update.

3. Explicitly add com.android.support:support-core-ui:27.1.1 to your dependencies.

Let me know if it helped.

Good luck.

Update:

If you go to

https://repo.jfrog.org/artifactory/libs-release-bintray/com/android/support/support-core-ui/27.1.1/

You'll find out that your *.jar file is not there.

There are a couple others, though:

• support-core-ui-27.1.1-sources.jar
• support-core-ui-27.1.1.aar
• support-core-ui-27.1.1.pom

You can use the *.aar file instead.
