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 one time by identified file

Example calls

npm-groovy-lint --path . --files myfile.groovy

npm-groovy-lint --path . --files myfile.groovy -c .groovylintrc.json

npm-groovy-lint --path . --files myfile.groovy -c .groovylintrc.json --fix

Help content

npm-groovy-lint [options]

  -p, --path path::String      Directory containing the files to lint (default: current directory) - default: .
  -f, --files String           Comma-separated list of Ant-style file patterns specifying files that must be included
  -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
  -x, --fixrules String        Option for --fix argument: List of rule identifiers to fix (if not specified, all available fixes will be applied) - default: all
  -i, --ignorepattern String   Comma-separated list of Ant-style file patterns specifying files that must be ignored. Default: none
  -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
  -l, --loglevel String        Log level (error,warning,info) - either: error, warning, or info - default: info
  --verbose                    More outputs in console, including performed fixes
  --failon String              Defines the error level where CLI will fail (return code = 1). error,warning,info or none. Every failure level includes the more critical ones. - either: error, warning, info, or none - default: none
  --failonerror                (Deprecated) Fails if at least one error is found
  --failonwarning              (Deprecated) Fails if at least one warning is found

  --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
  -j, --javaexecutable String  If you do not want to use default java executable to run CodeNarcServer, you can override it - default: java
  --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
