Question Gradle build failed

Hello
So I am trying to build an apk in unity 2020.3.3, I have all the sdk, jdk 1.8.0_77 and ndk r19 and I am using the unity Gradle
But each time I try to build an apk I keep getting an error, I have tried an empty project and also tried modifying my mainTemplate file, but the Gradle keeps looking for dependencies to download, please I need your help to resolve this issue

You should really update your Unity version, if you have 2020.3.3 installed, then you should update to at least 2020.3.15 because there was an update to the gradle plugin from that version (source: Unity - Manual: Gradle for Android (unity3d.com)). Latest minor version is 2020.3.48 so you are really behind.

Second issue is that you have jcenter() in your gradle repositories, which is deprecated. If you can't find it in your template then you probably need to look inside ""C:\Program Files\Unity\Editor\Data\PlaybackEngines\AndroidPlayer\Tools\GradleTemplates" and replace jcenter() with
mavenCentral().

Another issue is that according to the table inside Unity Manual (link above), the Gradle plugin 5.6.4 should have Android Gradle Plugin 4.0.1 for Unity versions from 2020.3.1 up to 2020.3.14. But it seems that you are requesting version 3.6.0. You probably upgraded to the 2020.3.3 from earlier Unity version and forgot to update your gradle templates.

 

Hello and thank you for your reply, I will update it and post my results here, thank you so much

 

Hello so I updated to 2020.3.35
And I used internet connection to build my apk under development build
And it built my apk just fine
But when I unticked it

I got this new error

Any help?

 

1. Are you using Android SDK, NDK etc. that is bundled with the Unity? If not then try to build with the bundled versions.
2. Try to build apk from clean project, if it works then it is configuration problem.
3. Try to disable minify/proguard.
4. Disable your custom gradle templates/properties.

If any of the above works, then you will be closer to finding the issue.

 

In the number one u wrote, what do you mean by bundled version

 

You can find it inside Preferences>External Tools.
