Group Main was not found when calling Dependencies.Remove for last dependency #1950

mrward · 2016-10-08T12:29:00Z

Description

Programmatically removing the last NuGet package from a paket.dependencies file, using Dependencies.Remove, throws an 'Group Main was not found' exception.

Paket version: 3.21.4

Repro steps

Create a paket.dependencies file containing a single NuGet package:

source https://www.nuget.org/api/v2
nuget NUnit
Install the NUnit NuGet package using paket install

3, Then programatically remove the NUnit NuGet package using code similar to the following C# code:

Dependencies
    .Locate (dependenciesFileName)
    .Remove (packageId);

Expected behavior

The NuGet package is removed from the paket.dependencies file without any exception.

Actual behavior

The NuGet package is removed from the paket.dependencies file but an exception is thrown.

Removing NUnit from d:\temp\test\paket.dependencies (group Main)
Dependencies files saved to d:\temp\test\paket.dependencies
Group Main was not found in d:\temp\test\paket.dependencies.

System.Exception: Group Main was not found in d:\temp\test\paket.dependencies.

Known workarounds

If the paket.dependencies file has two NuGet packages (e.g. NUnit and jQuery) then removing the NUnit package works without any exception being thrown.

Removing NUnit from d:\temp\test\paket.dependencies (group Main)
Dependencies files saved to d:\temp\test\paket.dependencies
Resolving packages for group Main:
 - jQuery 3.1.1
Locked version resolution written to d:\temp\test\paket.lock
Garbage collecting NUnit

I get the same behaviour if I try to remove the last NuGet dependency using paket.exe remove nuget nunit from the command line:

paket.exe remove nuget nunit --verbose
Paket version 3.21.4.0

Removing nunit from D:\temp\test\paket.dependencies (group Main)

Paket currently throws an error when removing the last NuGet package: Group Main was not found in paket.dependencies. fsprojects/Paket#1950 This left the UI and files still showing the original information even though Paket does remove the NuGet package from the dependencies and references files. So now the addin still notifies that these files have changed when there was an error removing a NuGet package. This ensures the Solution window is updated with the correct information and the files are reloaded if they are open in the text editor.

Should be fixed in latest version. Can you please retry?

I am still seeing the same error with Paket 3.25.2.0
