MSB4018
近期在編譯.Net Core時發生
Microsoft.NET.Sdk.targets(129, 5): [MSB4018] /usr/local/share/dotnet/sdk/2.2.301/Sdks/Microsoft.NET.Sdk/targets/Microsoft.NET.Sdk.targets(129,5): error MSB4018: The "GenerateDepsFile" task failed unexpectedly.

stackflow上面有人寫將nuget cache清空
也有人寫將.net core SDK更新
也有人說是MacOS底下才會產生的錯誤
要改MsBuild.dll
(https://rider-support.jetbrains.com/hc/en-us/articles/360004180039)
但實際試過後都沒有效果
最後發現在整個方案下的出錯的那個專案底下的csproj裡面
用文件編輯器打開來看多了一項
<HintPath>..\xxxx\bin\Release\netcoreapp2.1\xxxx.Api.dll</HintPath>
然後把這行註解或是刪除掉
就可以重新編譯了
