13.51.15 Building Error

I have a student trying to web GL build a project and it keeps giving us the same error (see image). We have moved the build fodler, moved the “Bee” folder and still it maps back to this original folder. Any suggestions? Or further information I should put in here for clarificaiton?

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 misconfigured or incorrectly-installed or incompatible third-party libraries such as Firebase or AdMob or IronSource.

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.

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):

Android Gradle errors and other related stuff:

Android SDK35 stuff:

is L a network drive? have you tried dumping it locally to c:\unity or such?

Yes, L is a network drive. We moved EVERYTHING to the desktop and told it to build there but it still keeps routing back to the network drive. It won’t accept our new folder on the desktop. Any suggestions?

Is there a symlink in the project?
Is that file/folder perhaps hardcoded in the project ie via editor script?

Try deleting the Library folder.

you need to open it like a new project from the local folder, and of course you can disconnect the network drive to make sure its not using it… and make sure the build folder is pointing local etc.

Hi, student with the problem here. I moved it and opened as you said, and it had the same error with the same thing but with the new filepath.

I tried deleting the rsp file causing the error but it regenerates on build. What should I do next?

Dont be building to your desktop, that madness windows tries to process all the changes..

We took it off the server that’s why it’s on the desktop. Is that the cause of the error?

Hey just general update on what has happened. While trying to publish my 3D game through webGL I kept getting the same error having to do with an rsp file. I’ve tried moving the build folder, the whole project, and deleting the rsp file in question as some comments have suggested. I keep getting the same error no matter the file path and after deleting when building it regenerates. The “Bee” folder its in also regenerates.


Any suggestions as to how to fix?

Stop building it on your desktop as per my post 1st May.

But Im done. You clearly wont listen
