[feature] Better error message on error in workspaces

[ibrawada]

What is your suggestion?

Hello all,

I was trying to do a conan workspace super-install on a project with around 10 components and it always failed with following error message. From the logs i couldn't tell what is the actual problem or where the problem is.

ERROR: Traceback (most recent call last):

ERROR: Node Editable

Now i am almost 100% sure that the problem was that an intermediate library was not part of the workspace and the problem disappeared as soon as it was added.

1. Is it possible to have Conan show the name of the package/reference that has a problem?

2. Would it also be possible for Conan to analyse the graph and notify the developer that between libA and libD there are libB and libC that are not part of the workspace and should be added?

Thanks in advance

Have you read the CONTRIBUTING guide?

Hi @ibrawada

Thanks very much for reporting.

You are totally correct, this is because when packages that are in the cache have dependencies to packages in the workspace, the workspace cannot be collapsed in a "super-install", so it fails.

I agree that a better diagnostic is worth it, so I have done #19013 to implement it, it is planned for next 2.22 (the 2.21 is already branched, couldn't make it)

Many thanks!
