Package.getActivationCommands is deprecated.

This deprecation message appears since Atom 0.189.0:

Use activationCommands instead of activationEvents in your package.json
Commands should be grouped by selector as follows:

  "activationCommands": {
    "atom-workspace": ["foo:bar", "foo:baz"],
    "atom-text-editor": ["foo:quux"]
  }

Package.getActivationCommands (D:\Programme\Dokumente\Atom\resources\app\src\package.js:764:9)
Package.hasActivationCommands (D:\Programme\Dokumente\Atom\resources\app\src\package.js:689:20)
