NX Passed 11161 file paths to Git to hash, but received 11148 hashes.

[jonhamm]

Current Behavior

This is effectively a re-open of : #8779

After upgrading

• node from 14.16.1 to 16.14.2
• npm from 6.14.12 to 8.5.0
• nx from 13.8.0 to 13.10.3

I have frequent builds on my Jenkins builds failing with errors like
> NX Passed 11161 file paths to Git to hash, but received 11148 hashes.

Expected Behavior

• The hashing should log the error returned from git hash-object e.g. fatal: Cannot open 'xxxx': No such file or directory
• If the hashing fails builds should not fail - i.e. the build should proceed nx caching disabled

Steps to Reproduce

Have not seen the pattern that causes these errors to occur
The proposed improvement in "Expected Behaviour" will not solve the problem but will

• provide more info that could make it possibly solve the error - e.g. from > NX Passed 7460 file paths to Git to hash, but received 1709 hashes. #8779 one solved the problem by adding a directory with temporary files to .gitignore and this might also be a solution to my problem, but which directory ??
• mitigate the effect of the problem by allowing the build to complete albeit without caching

It appears to be related to having run-commands execute nx run-many ... --parallel

   "%lint": {
      "executor": "@nrwl/workspace:run-commands",
      "options": {
        "parallel": false,

        ]

    },

I now realised this is a node 16.14.2 induced problem

In this setting I do get the error immediately

But in this setting which is similar except for the node version there is no problem

Turned out the problem was that .npm was not in .gitignore
It would however be very useful to get the stderr output from the spawned child process git hash-object ..... as this would have revealed this problem immediately so I will leave the issue open...

[julianpoemp]

I still get this error using Nx v14.1.7, Node v16.15 . Do you know how to fix this? The only workaround that I found is to restart my computer...

My error message:

nx serve api                
nx run [project][:target][:configuration] [_..]

Run a target for a project
(e.g., nx run myapp:serve:production).

You can also use the infix notation to run a target:
(e.g., nx serve myapp --configuration=production)

You can skip the use of Nx cache by using the --skip-nx-cache option.

I think you have to run git hash-object and add the folder with the error to .gitignore.

[julianpoemp]

I think you have to run git hash-object and add the folder with the error to .gitignore.

thank you! I found out that the error happens as soon as I generate files outside the Nx scope (in my case a build from pkg) that's recognized by git. As soon as I add these files to .gitignore the problem is fixed.
