Configuration in MegaLinter

Enable npm-groovy-lint by adding GROOVY_NPM_GROOVY_LINT in ENABLE_LINTERS variable
Disable npm-groovy-lint by adding GROOVY_NPM_GROOVY_LINT in DISABLE_LINTERS variable

Enable autofixes by adding GROOVY_NPM_GROOVY_LINT in APPLY_FIXES variable

Variable	Description	Default value
GROOVY_NPM_GROOVY_LINT_ARGUMENTS	User custom arguments to add in linter CLI call Ex: `-s --foo "bar"`
GROOVY_NPM_GROOVY_LINT_COMMAND_REMOVE_ARGUMENTS	User custom arguments to remove from command line before calling the linter Ex: `-s --foo "bar"`

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_files CLI 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.
Note: command-line arguments have priority on config file properties - default: /
  --format                     Format source code
  --fix                        Automatically fix problems when possible

  -r, --rulesets String        RuleSet file(s) to use for linting. If it is a directory, all rulesets will be used. RuleSet file definition: http://codenarc.github.io/CodeNarc/codenarc-creating-ruleset.html. If not specified, npm-groovy-script default one will be used. 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

  --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
