Question Gradle build failed

Hi everyone. I've got an android project going on and it all goes smoothly until i try to implement ads. As soon as i turn on the unity ads and install the ads package, my game doesn't build anymore and gives me this Gradle build failed error. I've really tried anything so everything helps.
Thank you.

It is recommended that the compiler be upgraded.

Maybe don't have the project in a onedrive folder. Run everything locally and make sure the android module and submodules are installed via unity hub (and select 'use installed with unity' in preferences - 3rd party tools)

 

How to troubleshoot build failures:

First, make a blank project with a single blank scene and prove that it builds successfully.

If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.

Until you can build a blank project to the target platform, don't fiddle with anything else.

Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.

Most often things that prevent building are third-party libraries such as Firebase.

Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.

It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.

Android build not building:

Recently (circa July 2022) there have been reports of Unity's installer failing to install the Android Tools.

Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:

OneDrive and any of those drive backup utilities are expressly not supported by Unity.

Please consider using proper industrial-grade enterprise-qualified source control in order to guard and protect your hard-earned work.

Personally I use git (completely outside of Unity) because it is free and there are tons of tutorials out there to help you set it up as well as free places to host your repo (BitBucket, Github, Gitlab, etc.).

You can also push git repositories to other drives: thumb drives, USB drives, network drives, etc., effectively putting a complete copy of the repository there.

As far as configuring Unity to play nice with git, keep this in mind:

I usually make a separate repository for each game, but I have some repositories with a bunch of smaller test games.

It is only simple economics that you must expend as much effort into backing it up as you feel the work is worth in the first place. Digital storage is so unbelievably cheap today that you can buy gigabytes of flash drive storage for about the price of a cup of coffee. It's simply ridiculous not to back up.

If you plan on joining the software industry, you will be required and expected to know how to use source control.

For me it was having my project in an external drive, spent all day trying to fix this. Moved it to my documents folder, and the build ran flawlessly. Wish you luck!
