},
"extends": [
"eslint:recommended"
],

}


you can see that I have added two plugins: eslint-plugin-dollar-sign and eslint-plugin-jquery.

why does not work this rule ?

"dollar-sign/dollar-sign": [
2,
"ignoreProperties"
]

Answer

You are missing

"env": {
  "browser": true,
  "commonjs": true,
  "es6": true,
  "jquery": true
},

$ is not declared as a global without jquery environment enabled. Because of that, you are getting a no-undef error, saying that you are using variable that haven't been declared.
