Gradle won't build

[DeMagischeZeekoe]

Knock knock.
Who’s there?
Gradle.
Gradle who?
Gradle build failed. See the Console for details.

So suddenly my android game doesn’t want to build, due to the gradle build failing.
Here are the three errors:

Please help me I tried almost everything I could find on the internet.

[MelvMay]

Please don’t use the 2D tag unless you’re asking about 2D as this puts it in the 2D product area and your question is nothing to do with 2D features.

Please use tags that relate to the question you’re asking.

I’ll remove the tag for you.

Thanks.

Knock knock.
Who’s there?
Gradle.
Gradle who?
Gradle build failed. See the Console for details.

^ ^ ^ This is another fantastic teeshirt idea!!!

Sorry to hear about your Gradle… see link at the bottom of this massive blurb of text about builds in general, there’s some Gradling to be had in there.

Gradle, gradle, gradle…

How to troubleshoot build failures:

Obviously, if there is actionable data, clues or information within any of the errors, fix those problems. Each error entry may have more information than can fit in the console log so select each error and read the expanded view below it.

If that gives you nothing worthwhile (look to Google! You’re never the first one!), then…

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:

Circa July 2022 here have been reports of Unity’s installer failing to install the Android Tools.

Can't build for Android

Latest Hub 3.2.0 in combination with Unity 2021.3.6 can’t build for Android because there is a missing Tools folder inside *Editor\Data\PlaybackEngines\AndroidPlayer* so Unity can’t find gradle. That folder is simply not created during the installation. The workaround is to copy the whole Tools folder from the previous Unity version or if you don’t have the previous version then do what [mention|1j+oWeNEPCI6ejbN15sncw==] says in the post below .

Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022 (edited on August 23, 2023 to include Android SDK 33…) (and again for SDK34):

.AAB Build Targeting API Level 33 on Unity 2021.3.8 with JDK 1.8

Hey, coincidentally I just upgraded to Android SDK31 today… why not wait until nearly the last minute? It was a wild ride, took most of the day. Let me tell you what I did, what I found. First of all, I’m using Unity2020.3.41 (hereinafter referred to Unity*) because that’s all the further I need to go forward right now. I found that Unity* only accepts up to SDK30.0.3 tools, but will build using those tools and SDK31. Next I found that Android Studio will not install anything except Android …
