[Bug] Unable to build from source, MacOS 11.4.

[JimmyDeemo]

[REQUIRED] Please fill in the following fields:

• Unity editor version: 2019.4.24f1
• External Dependency Manager version: Latest
• Source you installed EDM4U: Trying to build from source
• Features in External Dependency Manager in use: Android resolver, iOS resolver
• Plugins SDK in use: N/A
• Platform you are using the Unity editor on: Mac

[REQUIRED] Please describe the issue here:

I am unable to build from source with a fresh clone of the master branch. I am running MacOS 11.4 and it appears that mono will not execute on this platform. See attached log. Please advise if I am able to build from source using this platform and if not, please can a feature request be added for support? building_resolver.log

Please answer the following, if applicable:

What's the issue repro rate? 100%

What happened? How can we make the problem occur? Fresh clone of the master branch. Navigate to the project directory and execute ./gradlew build --stacktrace --info. Build fails.

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

[JimmyDeemo]

Seems similat to #448.

Hi @JimmyDeemo,

When utilizing the resolver, you can add this in your project by importing the .unitypackagefile or using the Package Manager. In order to identify what's causing this behavior, could you provide the complete steps in replicating this issue?

[JimmyDeemo]

Hello @paulinon

I'm not trying to utilise the resolver. I am trying to build from source from my own fork so I can attempt a fix for #427 and possibly contribute to the project.

Building from source is referenced here; https://github.com/googlesamples/unity-jar-resolver#building-from-source. It only says to run .gradlew build which I have done and have found my setup has an error.

Are there more pre-requisites needed? Can I build from source without mono? Please help me to build from source rather than integrating the package. I would be happy to file this issue in another way if that would be helpful.

[paulinon]

Thanks for the additional information, @JimmyDeemo. While we identify what's causing the issue, could you confirm if you're running on an M1 Mac?

[JimmyDeemo]

I can confirm I am not using an M1 Mac. It is a MacBook Pro. I have tried to run the mono version command manually and get the same error. Perhaps something to do with my Unity installation?

Thank you for being interested in contributing to EDM4U!

Currently EDM4U requires Unity 2017+ in your desktop to build. You also need to setup the environment variable like the following (in .bashrc or .bash_profile)

export UNITY_EXE="/Applications/Unity/Hub/Editor/2018.4.36f1/Unity.app/Contents/MacOS/Unity"

Based on the log, I believe you got this part covered.

Also, EDM4U build script requires mono executable to build C# code. I did noticed that Unity moved mono to a different folder in Unity 2019.4.28...which is unfortunate.

/Applications/Unity/Hub/Editor/2018.4.36f1/Unity.app/Contents/Mono/bin/mono -V
/Applications/Unity/Hub/Editor/2019.4.28f1/Unity.app/Contents/MonoBleedingEdge/bin/mono -V

This log basically say that it cannot find mono based on MONO_EXE anymore

MONO_EXE: /Applications/Unity/Unity.app/Contents/Mono/bin/mono
Starting process 'command '/Applications/Unity/Unity.app/Contents/Mono/bin/mono''. Working directory: /Users/jamesdeeman/Dev/git/unity-jar-resolver Command: /Applications/Unity/Unity.app/Contents/Mono/bin/mono -V

FAILURE: Build failed with an exception.

EDM4U build script does have logic to find mono and cache it in gradle.properties. I wonder how your gradle.properties ended up cached a wrong value in it.

Any case, could you try to change your MONO_EXE in gradle.properties to the following:

MONO_EXE=/Applications/Unity/Unity.app/Contents/MonoBleedingEdge/bin/mono

Try again and see if builds?

BTW, just noticed that you need to bump up python version here to 3.9.4 because...

1. EDM4U build script depends on gradle-python-envs,
2. gradle-python-envs depends on python-build
3. And python-build removed definition for 3.9.3

Fun! :(

Side story, this JetBrains plugin is part of the reason why EDM4U does not build on Windows. Perhaps there is a better way to install Python locally to the project or just reuse the existing one. :/

[JimmyDeemo]

Any case, could you try to change your MONO_EXE in gradle.properties to the following:

Please be advised that I do not have a gradle.properties file in the project. This is because the build script fails prior to this line File projectPropertiesFile = new File(scriptDirectory,"gradle.properties"). Therefore nothing is cached. Should I define MONO_EXE via an export similar to what you advised for UNITY_EXE?

BTW, just noticed that you need to bump up python version here to 3.9.4 because...

I will endeavour to update to this version of python.

[chkuang-g]

That is odd.

First of all, could you make sure if /Applications/Unity/Unity.app/Contents/MonoBleedingEdge/bin/mono exists?

Second, could you run with --no-build-cache and --no-daemon? That is, try to run this way:

./gradlew --no-build-cache --no-daemon build

And yes, doing the following shall do as well.

export MONO_EXE=/Applications/Unity/Unity.app/Contents/MonoBleedingEdge/bin/mono

Sorry for the inconvenience. I tried to build with 2019.4.28f1 and did not see any error like yours. I am a bit confused about why it happened as well.

[JimmyDeemo]

Yes, that path does indeed exist. Note: The version of mono there is different from the one in the 2019 installation;

Running ./gradlew --no-build-cache --no-daemon build without adding the MONO_EXE export didn't work. I have also tried setting this export with both versions of mono listed above and get a similar error though it does seem to be getting further. I noticed that the gradle.properties file had cached the standard versions too so cleared it such that it would cache the 2019 path but still it didn't build. I have attached logs of both attempts.

Very sorry, I just don't know what is wrong with my setup. Conflicting mono versions perhaps? Gradle issues? I also noticed that the python installed with Homebrew was greater than the version you mentioned, could the build process be using an older version? How would I check that?

I think the better solution is to add CI build test for EDM4U against different version of Unity from different OS.

Will update once we have something like this.
