Configuration in MegaLinter
- Enable npm-groovy-lint by adding GROOVY_NPM_GROOVY_LINTin ENABLE_LINTERS variable
- Disable npm-groovy-lint by adding GROOVY_NPM_GROOVY_LINTin DISABLE_LINTERS variable
- Enable autofixes by adding GROOVY_NPM_GROOVY_LINTin APPLY_FIXES variable

Behind the scenes
How are identified applicable files
- File extensions: .groovy,.gvy,.gradle,.nf
- File names (regex): Jenkinsfile
How the linting is performed
- npm-groovy-lint is called once with the list of files as arguments (list_of_filesCLI lint mode)
Example calls
npm-groovy-lint myfile.groovy
npm-groovy-lint -c .groovylintrc.json 
npm-groovy-lint -c .groovylintrc.json --fix myfile.groovy myfile2.groovy
Help content
npm-groovy-lint [options]
  --ext [String]               Specify Groovy file extensions
  -s, --source String          Source text to lint (if no path/files arguments)
  --sourcefilepath String      Full path of the file whose content is sent in source argument
  --parse                      Try to parse the source code with GroovyShell and return errors (use argument --no-parse if you want to deactivate)
  -c, --config String          Custom path to directory containing GroovyLint config file.
 Default: Found groovylintrc.js/json/yml/package.json config file, or default npm-groovy-lint config if not defined.

Can also be a list of rule identifiers with parameters
  --rulesetsoverridetype String  If list of rules sent in rulesets option, defines if they replace rules defined in .groovylintrc.json, or if they are appended - either: replaceConfig or appendConfig - default: replaceConfig
  -o, --output String          Output format (txt,json,sarif,html,xml), or path to a file with one of these extensions - default: txt

  --codenarcargs               Use core CodeNarc arguments (all npm-groovy-lint arguments will be ignored). Doc: http://codenarc.github.io/CodeNarc/codenarc-command-line.html
  --noserver                   For better performances, npm-groovy-lint runs a local server to eep CodeNarc alive instead of loading java/groovy at each call. If you don't want that, send this argument
  --serverhost String          If use of CodeNarc server, host where is the CodeNarc server (default: localhost) - default: http://localhost
  --serverport String          If use of CodeNarc server, port of the CodeNarc server (default: 7484) - default: 7484

  --javaoptions String         Override java options - default: -Xms256m,-Xmx2048m
  --killserver                 Terminate the CodeNarcServer if running
  --nolintafter                Do not lint again after format and fix options (useful for client calling Npm Groovy Lint)
  --returnrules                Return rule descriptions and url if this argument is set
  --insight                    npm-groovy-lint collects anonymous usage statistics using package https://www.npmjs.com/package/insight. If you want to enable them, use --insight option
