eslint 2.10.1 - Parsing error: Unexpected token

What version of ESLint are you using? 2.10.1

What parser (default, Babel-ESLint, etc.) are you using? babel-eslint

Please show your full configuration:

module.exports = {
    "extends": "airbnb",
    "parser": "babel-eslint",
}

What did you do? Please include the actual source code causing the issue.

I have a sample demonstrating the issue at: https://github.com/michael-wolfenden/eslint-2-10-1-issue

but running eslint via webpack with:

export class Counter {
  static initialCount = 0;
}

generates the error:

C:\Dev\eslint-issue\Counter.js
  2:23  error  Parsing error: Unexpected token =

What did you expect to happen? No errors

What actually happened? Please include the actual, raw output from ESLint.

C:\Dev\eslint-issue\Counter.js
  2:23  error  Parsing error: Unexpected token =

Addition information

The issue first occurred with 2.10.0 so at first I assumed it was the same issue as #6158 , however upgrading to 2.10.1 didn’t fix the issue. It appears as though the eslint babel parser isn’t kicking in.

Another thing to note is that the issue only occurs when running eslint via webpack.

Any ETA on the “fix” release?

Thanks for the comments everyone - we are investigating this issue as quickly as we can. There’s some disagreement over the correct approach to fixing the problem, so we’re working to resolve that. If you are stuck in the meantime, please consider downgrading to ESLint v1.9.0 until resolved.
