Cannot find dependencies when executing an assembly published by dotnet publish #3903

Open ymh199478 opened 4 years ago

This is more like a question, If this is not the right place to ask questions, I apologize in advance.

I wrote a .NET Core 2.0 console application (The main code is written by .netstandard2.0). Publish using dotnet publish, But there was an error during execution:

Compile project

dotnet publish src\Bucket.CLI\Bucket.CLI.csproj -c Release --self-contained false

Execute program

dotnet Bucket.CLI.dll

Prompt error:

Error:
  An assembly specified in the application dependencies manifest (Bucket.CLI.dep
s.json) was not found:
    package: 'System.Text.Encoding.CodePages', version: '4.5.1'
    path: 'runtimes/win/lib/netcoreapp2.0/System.Text.Encoding.CodePages.dll'

But, if I specify a --runtime, then no error will occur：

Compile project

dotnet publish src\Bucket.CLI\Bucket.CLI.csproj -c Release --self-contained false -r win-x64

Execute program

dotnet Bucket.CLI.dll

The program works fine.

What did i do wrong?

cc: @ericstj I wonder why the "runtime agnostic" is not finding the file in the package, but the -rid specific is working just fine. Do you have any ideas?

ericstj commented 4 years ago

When specifying runtime the SDK doesn't write things to RID-specific folders, it flattens everything to a single directory. This sounds like an SDK issue with deps file or publish. Transferring.

I tried your repro by copy/pasting the files in stack overflow to the directory structure you mentioned and couldn't get it to reproduce. Would you be able to provide an isolated repro of this?

ymh199478 commented 4 years ago

This problem can occur in .net core 2.0, 2.1, 2.2.

isolated repro:

git clone https://github.com/yb199478/dotnet-publish-reproduce.git
cd dotnet-publish-reproduce

dotnet publish -c Release --self-contained false
cd src/Reproduce.CLI/bin/Release/netcoreapp2.0/publish

dotnet Reproduce.CLI.dll

I had the same problem:
dotnet Reproduce.CLI.dll

Error:
An assembly specified in the application dependencies manifest (Reproduce.CLI.deps.json) was not found:
    package: 'System.Text.Encoding.CodePages', version: '4.5.1'
    path: 'runtimes/win/lib/netcoreapp2.0/System.Text.Encoding.CodePages.dll'

I had the same problem: dotnet Reproduce.CLI.dll

Error:
An assembly specified in the application dependencies manifest (Reproduce.CLI.deps.json) was not found:
    package: 'System.Text.Encoding.CodePages', version: '4.5.1'
    path: 'runtimes/win/lib/netcoreapp2.0/System.Text.Encoding.CodePages.dll'

I get the same with a project targetting netcoreapp3.1, and there's no reference to CodePages anywhere in my repository.

That said, I've been doing a separate dotnet build step, then dotnet publish with --no-build. If I just run publish and let it build in the same command, then the problem goes away.

Also to add, build and then publish with no-build works running the published output on linux, but not on Windows.

jimmyheaddon commented 4 years ago

I've started seeing this same issue running the same for my own .NET Core 3.1 project:

dotnet publish $(ProjectPath) --configuration $(ConfigurationName) --framework netcoreapp3.1 --no-build"

Specifying --self-contained true and/or --runtime win-x64 doesn't help in my case, unfortunately. --self-contained false also doesn't help.

I also see an error for System.Runtime missing when running this in another environment, either by calling the .exe or the .dll output.
