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.

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:

.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 …

I´m using unity 2022.3.1f1 , now I tried to install every single module , only the language packs that I left unistalled , and then I tried to create a project 3D (core) and it didn´t fix the problem, is there another way to solve the problem , or I didn´t fix my unity in the right way?
I’m making a 3d open world just to give some information about that

Ok , I solved it , for the ones that may have this problem in the future , try installing all modules of the version you want and then restart ur pc , make sure that the unity is closed in the little arrow near the clock , and then run unity as admin and it should all be fine

[CodeCiya]

hello.
can I give the best and simplest solution for this?
actually, I got this error many times.
I searched on many platforms and I found a simple solution which is
you can delete the Library folder and if you don’t want to do it you can Onli Delete Library/Bee folder that will work

[Andrej-Vojtas]

Thanks, my computer switched off due to a power outage, and after rebooting the Unity project wouldn’t load, and deleting the Library folder worked!

[unity_F698945F1228165023E0]

i got he same issue on unity 2022.3.39 but i solved it by just deleting the Bee folder under library folder of you project. (Build Plateform were iOS)

[gmrufus]

I got the same error mentioned in this post, running 2022 LTS on Ubuntu. Happened after a crash while Unity was open. I also got Unity running again by deleting the Library/Bee folder as mentioned above – BUT my scene was empty!

I just wanted to mention I was working in the “Sample Scene” and while I thought my scene was missing / corrupted / otherwise busted I just had to load it from File > Open Scene then Assets/Scenes/SampleScene.unity

I spent a good hour panicking and couldn’t figure out why my work was “gone” even though everything was backed up / version controlled etc. Silly I know. Obviously I’m not super familiar with Unity basics – just adding this quick note in case anyone else freaks out even though their work is backed up.

[Sashell]

Hi, does anyone have this on unity 6.0 ? (58f2)

Deleting the Library folder and rebooting does nothing, project opens but I can’t build because of this error.
