[Bug] Unity 2021.2 fails to compile

[joaquingrech]

Unity 2021.2 alpha 20 currently fails to compile anything with the resolver on it.

The error is this:

AmbiguousMatchException: Ambiguous match found.

Hi @joaquingrech,

It seems that your inquiry doesn't follow the template. It would be great if you can provide more information related to your issue such as the operating system used, SDK version used, and the steps you've taken before facing the issue. This way, we can identify the possible cause of this behavior.

Thanks!

[joaquingrech]

Ok, SDK version: latest as of today. 1.2.165
OS: Windows 10
Unity version: 2021.2.0a20

It´s been happening for months in all 2021.2.0.a branch. I´ve contacted Unity but they send the ball here.

You just need to import the package and you´ll begin to get errors inmediately.

Hi @joaquingrech,

It looks like this exception is raised in C#, possible due to the C# libraries being upgraded or different in the Unity version you're using.

Could you try using a stable version of Unity 2021 (such as Unity 2021.1.11) and see if the issue persists?

[joaquingrech]

The stable (older) version works. The issue is in the newer and upcoming version of Unity. Unity upgraded their libraries and compiler to a newer .Net. From now on, they will be using those libraries. What this means is that the resolver won't work in its current state.

That's exactly why I'm reporting this issue before Unity 2021.2 comes out of beta and hits the fan.

It's also a major problem because we can't test the next release of Unity. Many of the libraries and games that we use to test are using the Google Resolver. Not having it working, won't allow for many of the tests to make sure Unity 2021.2 is running properly before official release.

Thank you for clarifying and thank you for the heads up.
Just took a quick look at this Unity thread and looks like 2021.2 has a bunch of incoming changes. I will bring this up to the team and add this to our roadmap.

More information is in the duplicate #447 as mentioned above.

Hi folks,

Thanks to @patm1987's PR #449, the fix was merge into the repo.

I'll prepare another release of EDM4U soon.

If you need the patch right away, you can build EDM4U from source using the following commands:

# Build .unitypackage under 'build/' folder
./gradlew buildPlugin

# Build .tgz under 'build/' folder
./gradlew buildUpmPlugin

EDM4U 1.2.166 is available for both .unitypackage and .tgz format now.
