[Question] How to build from source

[derwaldgeist]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2023.3.11f1
• External Dependency Manager version: 1.2.177
• Platform you are using the Unity editor on: Mac with Silicon chip

[REQUIRED] Please describe the question here:

I am trying to build the project from source. I installed JDK 11 on my Mac, since I realized that the Gradle version required was not working with a newer JDK.

However, I am still running into an error:

> Configure project :
Mono 6.13.0 detected which will generate .pdb files that are not compatible with older versions of Unity. This can be fixed by compiling with Unity 5.6.

> Task :compileVersionHandler FAILED

>>>> xbuild tool is deprecated and will be removed in future updates, use msbuild instead <<<<

Note that this Unity Editor version is an Apple Silicon build. It seems as if the build script is using the first Editor it can find.

This issue does not seem to follow the issue template. Make sure you provide all the required information.

I tried to uninstall the 2023.3.11f1 Editor in favor of 2023.3.13f1, hoping it would pickup the Intel version, but then I got

Unity editor executable (UNITY_EXE) not found

[derwaldgeist]

Did some additional research. It did not find the Unity application since it stores its path in gradle.properties on first run. I don't think this is a good idea, since Unity installations tend to change often.

After I removed the content of this file, I am now getting this again:

Process 'command '/Applications/Unity/Hub/Editor/2022.3.13f1-x86_64/Unity.app/Contents/MonoBleedingEdge/bin/xbuild'' finished with non-zero exit value 1

I tried with both the Silicon and Intel versions of Unity. But both show the same problem, even if I run gradlew with Rosetta.

I ran gradlew again, but patched the verbosity level in line 1044 to "detailed".

This resulted in this log:

for both the Silicon and the Intel versions of the Unity editor.

If I understand things correctly, this attribute is breaking things: https://github.com/googlesamples/unity-jar-resolver/blob/ae200afe800c179e7d24d8b5653cbe71bcd238b7/source/VersionHandler/src/VersionHandler.cs#L32
