Running build in watch mode for buildable node libraries does not generate a package.json as part of the output.

Current Behavior

Running build in watch mode for buildable node libraries does not generate a package.json as part of the output.
This breaks incremental building as dependents of this library keep telling me that it is not built.

Expected Behavior

package.json should be generated in watch mode.
This was the behavior up to @nrwl/node v11.4.0.
After v11.4.0, watch mode was broken (#5208), which was fixed in v12.3.4

Workarounds

I wrote a watch target for the library:
I had to deliberately skip-nx-cache to avoid race condition, too

"watch": {
    "executor": "@nrwl/workspace:run-commands",
    "options": {
        "parallel": true,
        "commands": [
            {
                "command": "npx nx build models --watch"
            },
            {
                "command": "npx nx build models --skip-nx-cache"
            }
        ]
    }
},

Additonal info:

In @nrwl/node v11.4.0, the output for npx nx build project --watch would be

9:35:57 am - Starting compilation in watch mode...


9:35:59 am - Found 0 errors. Watching for file changes.
Copying asset files...   
Done copying asset files. 

In v12.3.4, the output is

1:19:33 pm - Starting compilation in watch mode...


1:19:34 pm - Found 0 errors. Watching for file changes.

This seems to suggest that in the v12.3.4 once it enters watch mode, no further additional processing is done, which was being done in v11.4.0

Has this been released?

[AgentEnder]

Hey @DibyodyutiMondal. This is in latest master, but has not been released yet. It should be part of the next patch or minor version, whichever comes first.

[DibyodyutiMondal]

The issue has become worse in v12.6.0-next

Forget package.json, now there is absolutely no output at all

New issue or reopen this one?

[AgentEnder]

@DibyodyutiMondal I'll check this out today, see if I can reproduce.

[DibyodyutiMondal]

The problem seems resolved in v12.6.2
