Steps to Reproduce

Not sure if this is a mistake on my end, so I quickly created a fresh nx workspace to test it out following along https://nx.dev/nx/create-nx-workspace:

yarn create nx-workspace
integrate monorepo
repository name temp
application name tempapp
default stylesheet css

I followed https://nx.dev/recipes/generators/local-generators to create a plugin and generator

npm install @nrwl/nx-plugin@15.3.0
nx g @nrwl/nx-plugin:plugin my-plugin
nx generate @nrwl/nx-plugin:generator my-generator --project=my-plugin

Trying to execute the generator results in an error:

nx generate @temp/my-plugin:my-generator mylib --verbose

Unable to find local plugin [ 'libs\\my-plugin\\src\\index.ts' ] Map(4) {
  'apps/my-plugin-e2e' => 'my-plugin-e2e',
  'apps/tempapp' => 'tempapp',
  'apps/tempapp-e2e' => 'tempapp-e2e',
  'libs/my-plugin' => 'my-plugin'
}

NX   Unable to resolve @temp/my-plugin:my-generator.

Using TS 4.9.4
Did I miss something or is this really a bug? I noticed that libs/my-plugin/src/index.ts is empty, but maybe that is supposed to be like that!?

This is also happening in our repo as well. NX 15.3.0 cannot resolve our local plugins. We had to revert to a previous version to get it working again.

Thanks for the workaround. I had the same issue with version 15.3.0. No issue with version 15.2.0.

After investigation I found that it was a Windows path format related issue. A fix to the problem is already merge #13801 so I guess the issue should be gone in close futur release :)

[bosycom]

Thanks @mottet for investigating!

For everyone who cannot wait for the fixed version, you can simply patch the src file in node_modules/nx/src/utils/nx-plugin.js like that which has fixed it for me:

Add new line 14

const { normalizePath } = require("./path");

Change line 134:

const possiblePaths = (_a = tsConfigPaths[importPath]) === null || _a === void 0 ? void 0 : _a.map((p) => normalizePath(path.relative(root, path.join(root, p))));
