UnityでのWindowsのexeファイルビルドに詰まった話

Unityでwindowsのexeファイルをビルドしようとしたエラーが出てしまいました。多分、Unity Standalone File Browserというアセットを使っていることが原因かと思います。解決法をメモしました。

github.com

まずはビルド

まず初めに以下のような設定で通常のビルドをしました。

すると以下のようなエラーが発生しました。

ArgumentException: The Assembly Mono.WebBrowser is referenced by System.Windows.Forms ('Assets/StandaloneFileBrowser/Plugins/System.Windows.Forms.dll'). But the dll is not allowed to be included or could not be found.
UnityEditor.AssemblyHelper.AddReferencedAssembliesRecurse (System.String assemblyPath, System.Collections.Generic.List`1[T] alreadyFoundAssemblies, System.String[] allAssemblyPaths, System.String[] foldersToSearch, System.Collections.Generic.Dictionary`2[TKey,TValue] cache, UnityEditor.BuildTarget target) (at C:/buildslave/unity/build/Editor/Mono/AssemblyHelper.cs:154)
UnityEditor.AssemblyHelper.AddReferencedAssembliesRecurse (System.String assemblyPath, System.Collections.Generic.List`1[T] alreadyFoundAssemblies, System.String[] allAssemblyPaths, System.String[] foldersToSearch, System.Collections.Generic.Dictionary`2[TKey,TValue] cache, UnityEditor.BuildTarget target) (at C:/buildslave/unity/build/Editor/Mono/AssemblyHelper.cs:160)
UnityEditor.AssemblyHelper.FindAssembliesReferencedBy (System.String[] paths, System.String[] foldersToSearch, UnityEditor.BuildTarget target) (at C:/buildslave/unity/build/Editor/Mono/AssemblyHelper.cs:194)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr)

これのエラーに少し似てそうな以下を参考に

teratail.com

C:\Windows\Microsoft.NET\Framework\v2.0.50727\System.Drawing.dll をAssetsフォルダ内にコピーしてBuild Settings...→Player Settings...→Other Settings→Configurationの API Compatibility Level の.NETのバージョンを Scripting running version と同じものに変更しました。

二つ目のエラー

初めのエラーは解消しましたが次に以下のエラーが現れました。

UnityException: Build path contains project built with "Create Visual Studio Solution" option, which is incompatible with current build settings. Consider building your project into an empty directory.

を参考にした結果、ビルドフォルダをドキュメントに指定したら無事にビルドできました。
