Nx should clear the cache after a migration

[PowerSupply]

Current Behavior

Here is a description of the problem that pointed me to the conclusion in the title:

After upgrading to 19.5 from 19.0.4 the dependency-check lint rule started to fail with false negatives.

It said: error The "@nx/devkit" package is not used by "xxx" project

But it is used! And the lint worked before the upgrade to 19.5. Running the command with --skip-nx-cache still fails. But what is weird is that going to the file where @nx/devkit is imported and just making a small inconsequential change to it (like moving the line with the import to being second instead of first) makes the error go away. And then it doesn't appear again.

Runningnx reset and then trying the command again seems to fix it which points to some sort of local cache error. I think Nx should reset itself when migrating to a new version since it seems like the cache becomes dirty. But I do not understand why the error still appeared when i used --skip-nx-cache.

Expected Behavior

The problem I had should not have appeared. Proposed solution is to run nx reset as a part of migration to a new version of nx.

Steps to Reproduce

1. Use Nx 19.0.4. Have a project that passes lint.
2. Upgrade to Nx 19.5.
3. Try to run the lint for the same project. It may fail even if it should succeed and making a small inconsequential change to the file where the import is fixes the problem. Nx reset also fixes the problem.

Same problem for me. Some libs disappear from the project graph, so the dependency-check can't find them (and other tasks too). And Nx reset doesn't solve the problem. Curiously it only happen on libs where the folder path contains "api" ( 'projects/api/.../project.json), but it's probably a coincidence.

• I save the project.json file of the lib
• nx show projects -> the lib returns in the project graph
• nx reset -> the lib disappear again

I've the problem on Ubuntu 20. It seems ok with @19.4.0.

Maybe resolved with https://github.com/nrwl/nx/pull/27338 ?

~I no longer have the problem with this version "nx": "19.6.2"~.

The problem was elsewhere:

• I had a .gitignore in the parent folder of my nx repo that affected the native glob method that is used by nx to retriev all project.json files in the workspace.
• This is a really strange behavior that doesn't happen until 19.4.4.
