Reflection baking error with built-in Unity package

[brookman]

After upgrading to Unity 2019.2 there is a built-in package for the Jetbrains Rider IDE. This package produces an error in the reflection baking while building:

ArgumentException: Invalid path
System.IO.Path.GetDirectoryName (System.String path) (at <a8ed250850854b439cedc18931a314fe>:0)
Zenject.ReflectionBaking.UnityAssemblyResolver..ctor () (at Assets/Plugins/Zenject/OptionalExtras/ReflectionBaking/Unity/UnityAssemblyResolver.cs:34)
Zenject.ReflectionBaking.ReflectionBakingBuildObserver.TryWeaveAssembly (System.String assemblyAssetPath) (at Assets/Plugins/Zenject/OptionalExtras/ReflectionBaking/Unity/ReflectionBakingBuildObserver.cs:65)
Zenject.ReflectionBaking.ReflectionBakingBuildObserver.OnAssemblyCompiled (System.String assemblyAssetPath, UnityEditor.Compilation.CompilerMessage[] messages) (at Assets/Plugins/Zenject/OptionalExtras/ReflectionBaking/Unity/ReflectionBakingBuildObserver.cs:37)
UnityEditor.Compilation.CompilationPipeline.<SubscribeToEvents>m__3 (System.String assemblyPath, UnityEditor.Compilation.CompilerMessage[] messages) (at C:/buildslave/unity/build/Editor/Mono/Scripting/ScriptCompilation/CompilationPipeline.cs:179)
UnityEditor.BuildPipeline:BuildPlayer(BuildPlayerOptions)

The problem is that assemblies[i].Location returns an empty string.
I am not sure if this is a problem with the package or with Zenject. But the Rider package is editor only so it should probably not be included in the reflection baking process.

This Zenject repo is not been updated since last year or so.
Have you tried the Extenject fork? As it's under active development and contribution.
