Cannot enable cache

[hakjac]

The following eslint configuration

eslint {
  executable = "./node_modules/eslint/bin/eslint.js"
  config = "./.eslintrc.json"
  inputs = ["src/**/*.ts"]
  cache = true
}

results in the following error message:

> Task :eslint FAILED
Caching disabled for task ':eslint' because:
  Build cache is disabled
Task ':eslint' is not up-to-date because:
  Task has not declared any outputs despite executing actions.
Starting process 'command './node_modules/eslint/bin/eslint.js''. Working directory: /home/hakjac/wsgit/hippo Command: ./node_modules/eslint/bin/eslint.js --config ./.eslintrc.json --cache true src/**/*.ts
Successfully started process 'command './node_modules/eslint/bin/eslint.js''

Oops! Something went wrong! :(

ESLint: 6.2.2.

No files matching the pattern "true" were found.
Please check for typing mistakes in the pattern.

I believe that the cache = true option should not result in --cache true but instead just a --cache

That cache options refers to eslint cache. Gradle caching is not the same thing. My PR I've opened adds caching to the task, but you might also add additional inputs to gradle task if you have non standard config.
