Microsoft.WebApplication.targets was not found #398

Open DamienCassou opened 6 years ago

DamienCassou commented 6 years ago

Omnisharp complains about missing WebApplication.targets. I have no clue what that means.

{"Event":"Error","Body":{"Text":"Microsoft.Build.Exceptions.InvalidProjectFileException: The imported project \"/home/cassou/.emacs.d/var/omnisharp/cache/server/v1.24.0/xbuild/Microsoft/VisualStudio/v15.0/WebApplications/Microsoft.WebApplication.targets\" was not found. Confirm that the path in the <Import> declaration is correct, and that the file exists on disk.  /home/cassou/Documents/projects/ftgp/monitor/monitor/Monitor.Web.Ui/Monitor.Web.Ui.csproj\n

In fact, there is no xbuild/ directory under v1.24.0. I can reproduce the problem with latest omnisharp-emacs and v1.26.0.

DamienCassou commented 6 years ago

This looks similar to https://github.com/OmniSharp/omnisharp-vscode/issues/1368.

DustinCampbell commented 6 years ago

It's not the same as https://github.com/OmniSharp/omnisharp-vscode/issues/1368. However, it would be good to get your full OmniSharp Log. In addition, what version of Mono do you have installed?

razzmatazz commented 6 years ago

@DamienCassou are you using the bundled server installable via omnisharp-install-server or did you build one for yourself?

@DustinCampbell on MacOS and Linux in omnisharp-emacs we are using the "specialized" server code from omnisharp-roslyn/releases page per platform, that have mono bundled.

are you using the bundled server installable via omnisharp-install-server or did you build one for yourself?

the bundled version. I let omnisharp-emacs do everything.

DustinCampbell commented 6 years ago

@razzmatazz yes, but OmniSharp does not include all of the MSBuild targets necessary to process every possible project. It just contains a minimal set. In particular, a .NET Framework Web Application targets are not included with OmniSharp, so it would try to locate them within a Mono installation on Mac/Linux.

@DamienCassou: From the log above, it looks like it the MSBuildExtensionsPath variable did not get set to /usr/lib/mono/xbuild. Could you try updating to the latest version of Mono? I'm not sure what distro you're using, but you can update to the latest (5.4.0) here: http://www.mono-project.com/download/#download-lin.

DamienCassou commented 6 years ago

@DustinCampbell: I'm on Fedora 26. I tried to follow the instructions on the link you gave me, but this results in conflicts with the package system:

DustinCampbell commented 6 years ago

Did you use the CentOS instructions? Those have worked for me on Fedora 26.

Regardless, if you can't update, you might be able to fix the issue by dropping an omnisharp.json file at the root of your repo with the following content:

{
    "MsBuild": {
        "MSBuildExtensionsPath": "/usr/lib/mono/xbuild"
    }
}

yes. This resulted in the addition of a download.mono-project.com_repocentos7.repo file in /etc/yum.repos.d. Still, this does not work.

Regardless, if you can't update, you might be able to fix the issue by dropping an omnisharp.json file at the root of your repo with the following content:


{
    "MsBuild": {
        "MSBuildExtensionsPath": "/usr/lib/mono/xbuild"

There is no xbuild in /usr/lib/mono:

DustinCampbell commented 6 years ago

Ok. That explains why OmniSharp didn't work correctly. It does sound like you'll need a newer Mono to get the WebApplication.targets on your machine that are needed to open this project. I don't know why the CentOS packages aren't working for you. Unfortunately, they've always worked for me so I've never had to troubleshoot them. I'll try setting up a new Fedora 26 VM today and see if those packages still install for me.

DustinCampbell commented 6 years ago

FWIW, I just tried on a clean Fedora 26 VM and was able to yum install mono-devel after following the CentOS 7 steps at http://www.mono-project.com/download/#download-lin-centos:

@DustinCampbell I gave it another shot and I managed to install 5.4 (I had to delete some packages for that).

I still have the same message though. Here is an extract of the log:

I still suffer from the same problem. Can anyone help me?

Try installing the Mono msbuild package: sudo dnf install msbuild

Thank you @DustinCampbell. This makes omnisharp-emacs basically working again. However, the error message still appears in the log

[16:16:40] ERROR: OmniSharp.MSBuild.ProjectFile.ProjectFileInfo, The imported project "/home/cassou/.emacs.d/var/omnisharp/cache/server/v1.26.0/xbuild/Microsoft/VisualStudio/v15.0/WebApplications/Microsoft.WebApplication.targets" was not found. Confirm that the path in the declaration is correct, and that the file exists on disk.

and I still get compilation errors that should not be there

"The type or namespace name 'ICanJson' could not be found"

Here is my log now:

@DamienCassou have you tried commenting out the lines with Microsoft.WebApplication.targets and AllRules.ruleset from your .csproj xmls?

you might not need those targets for building/loading in omnisharp because, I think:

@DamienCassou have you tried commenting out the lines with Microsoft.WebApplication.targets

this removes the error I had.

and AllRules.ruleset from your .csproj xmls?

I have no such thing in any file of my project.

if it helps you load the solution

the solution loads even when keeping the Microsoft.WebApplication.targets lines.

razzmatazz commented 6 years ago

Sorry, most probably I did not understand you before. Are those errors you listed in your previous comment blocking your workflow with omnisharp-emacs or just something that is shown on the log (but everything works ok otherwise)?

Everything works ok now as far as I can tell. But I'm still surprised by the amount of warnings in the log.

Regarding WebApplication.targets, our project has:

  <Import Project="$(VSToolsPath)\WebApplications\Microsoft.WebApplication.targets" Condition="'$(VSToolsPath)' != ''" />
  <Import Project="$(MSBuildExtensionsPath32)\Microsoft\VisualStudio\v10.0\WebApplications\Microsoft.WebApplication.targets" Condition="false" />

Do you see anything suspicious there? When using omnisharp, I have the impression that the first line triggers this error:

Microsoft.Build.Exceptions.InvalidProjectFileException: The imported project \"/home/cassou/.emacs.d/var/omnisharp/cache/server/v1.26.3/xbuild/Microsoft/VisualStudio/v15.0/WebApplications/Microsoft.WebApplication.targets\" was not found

Using locate gives me this result:

Is there something we could fix on the project to make it work for everyone?
