When trying to ctrl+Space to get code completion, nothing appears. Or If I try to cmd+Click on something like Console.WriteLine("Hello World!"); I get the following error.

Answer 1 · 2018-09-13T18:42:04.000Z

Can you try to run dotnet restore on the project and restart the IDE to check whether it changes something?

Answer 2 · 2018-09-13T19:00:08.000Z

Ran dotnet restore on the project and restarted Eclipse. If I double click on the NewDotnetProject2.csproj it states:

Answer 3 · 2018-09-14T06:57:53.000Z

I can reproduce it on Windows. It's a blocker for next release.

Answer 4 · 2018-09-14T14:16:30.000Z

I've rolled-back to another version of OmniSharp that doesn't have dotnet/vscode-csharp#2234 . Can you please give it a try, installing from http://download.eclipse.org/acute/snapshots

Answer 5 · 2018-09-14T15:09:39.000Z

I've tried this build locally, and it fixes the issue. I'm closing this as resolved, feel free to reopen if it's still failing for you.

Answer 6 · 2018-09-14T16:03:19.000Z

I tried to update ACute, but it is still coming up as 0.2.0.201809131513.

Answer 7 · 2018-09-14T16:19:19.000Z

Ok. Can you please mention which OS you're running, what's your dotnet --version, and whatever you think can help ?

Answer 8 · 2018-09-14T16:53:01.000Z

Versions:

Mac OS: 10.13
dotnet: 2.1.302
Eclipse: Photon Release (4.8.0) - Build id: 20180619-1200
Java: 1.8.0_161-b12
Mono Framework: 5.12.0

Is the Omnisharp in .metadata/.plugins/org.eclipse.acute/omnisharp-roslyn somehow modified or could I try downloading a particular release to replace it?

Answer 9 · 2018-09-14T16:57:13.000Z

It's a regular omnisharp, so you can try this with other apps, or try other omnisharp with this app.
Either you can tweak the content of the folder, or you can use environment variable as described in https://github.com/eclipse/aCute#alternative-configuration to provide alternative configurations of the Language Server, so you can link it to a local copy.

Answer 10 · 2018-09-14T18:42:23.000Z

I tried to update ACute, but it is still coming up as 0.2.0.20180913151

Can you restart the IDE? Content of update site is cached in memory and cache isn't flushed often. A restart guarantees cache is dropped and sites are really read again.

Answer 11 · 2018-09-14T20:29:01.000Z

I've quit and restarted Eclipse, but it's still showing that 0.2.0.20180913151 is the latest and already installed.

I will try using the v1.30.1 omnisharp-roslyn/release in metadata/.plugins/org.eclipse.acute/omnisharp-roslyn to see if that works.

Answer 12 · 2018-09-14T21:08:17.000Z

Using the version of ACute from 20180913 (still not seeing a new version) and I tried v1.30.1 and v1.30.0. First, I quit Eclipse, removed the omnisharp-roslyn folder. I extracted omnisharp-osx.tar.gz, and renamed the folder to omnisharp-roslyn and move it to the .metadata/.plugins/org.eclipse.acute/ folder. And with both version, I get the same as the one that was generated with ACute.

Answer 13 · 2019-02-27T01:37:50.000Z

Hi @AmigaAbattoir. I'm interested in trying this out on a Mac also but am a little uncertain about setting up pre-reqs.

You mentioned you are using

dotnet: 2.1.302

Are you using .NET Core as described here?
If not, how did you set up dotNet+mono? Did you start with Unity?

Answer 14 · 2019-03-01T04:43:49.000Z

Hi @AmigaAbattoir. I'm interested in trying this out on a Mac also but am a little uncertain about setting up pre-reqs.

You mentioned you are using

dotnet: 2.1.302

Are you using .NET Core as described here?
If not, how did you set up dotNet+mono? Did you start with Unity?

I installed the .NET Core SDK from https://dotnet.microsoft.com/download

Unfortunately, I could not get aCute running on my Mac. I did, however, end up paying for CodeMix, and I am able to edit C# with code completion for Unity projects in Eclipse.

I would still like to get aCute running, since with CodeMix acts more like an Eclipse replacement than nicely integrating into it.

Answer 15 · 2019-03-01T07:21:12.000Z

AFAIK, none of the current active contributors to aCute owns a Mac totry this. If you can try to debug aCute that'd be great.
Does workspace/.metadata/.log tell anything useful?

Answer 16 · 2019-03-02T19:05:00.000Z

Fresh copy of 2018-12, and aCute from http://download.eclipse.org/acute/snapshots.

I try importing a project from MSDN Basic calculator in C# by using Import Projects from File System or Archive.

Go into the Program.cs file and try to edit, I forgot to set the "dotnet path"

!ENTRY org.eclipse.acute 4 0 2019-03-02 13:37:49.208
!MESSAGE `dotnet restore` not performed!
Main issue and remediation: The `dotnet` path is not set in the .NET Core preferences. Please set it.
Possible alternative remediation:
* `dotnet` (v2.0 or later) is a prerequisite. Install it on your system if missing.

I then set the path, reopen Eclipse. When I looked at the Console I did find this error:

[Error]	[fail]: OmniSharp.MSBuild.ProjectLoader
        The reference assemblies for framework ".NETFramework,Version=v4.5" were not found. To resolve this, install the SDK or Targeting Pack for this framework version or retarget your application to a version of the framework for which you have the SDK or Targeting Pack installed. Note that assemblies will be resolved from the Global Assembly Cache (GAC) and will be used in place of reference assemblies. Therefore your assembly may not be correctly targeted for the framework you intend.
[Warning]	[warn]: OmniSharp.MSBuild.ProjectManager
        Failed to load project file '/Volumes/HackintoshSSD/Storage/Downloads/ACute test projects/MyCalculator/MyCalculator/MyCalculator.csproj'.

I figured I would try an new .NET project (a C# console app).

`Failed to load project file '/Users/abattoir/eclipse-2018-12-aCute-20190302-workspace/NewDotnetProject/NewDotnetProject.csproj'.

Is this file existing in the project? Is it a recent version of .NET Core you're using?

Answer 19 · 2019-03-28T22:08:34.000Z

Please have a look at dotnet/msbuild#2532 (comment) as possible workaround, and other comments on the issue that give hints about what can be the root cause (ie why MSBuild cannot properly detect project).

Answer 20 · 2019-03-29T01:38:51.000Z

So I tried from terminal changing my path with: PATH=$PATH:/usr/local/share/dotnet/sdk/2.1.504/

and then launching Eclipse from that terminal: /Applications/Eclipse.app/Contents/MacOS/eclipse

and I got code completion.

I still can't just open Eclipse and have aCute work.

Sorry, i can't help more with such mac-specific issues, especially since you found a reliable workaround.

I'm closing this one as there seems to not be interest from Mac users/developers to enhance acute and developers don't have access to mac machines thus can't do anything.
