CodeNarc can be run from the command-line as a Java application. The org.codenarc.CodeNarc
class provides the application entry-point.
Usage: java org.codenarc.CodeNarc [OPTIONS]
where OPTIONS are zero or more command-line parameters of the form “-NAME[=VALUE]”
All command-line parameters are optional. If no parameters are supplied, CodeNarc runs from the current directory with reasonable defaults, as described below.
| Parameter | Description | Example |
|---|---|---|
| basedir=DIR | The base (root) directory for the source code to be analyzed. Defaults to the current directory (“.”). | -basedir=src/main/groovy |
| includes=PATTERNS | The comma-separated list of Ant-style file patterns specifying files that must be included. Defaults to **/**.groovy. | -includes=**/**.gr |
| excludes=PATTERNS | The comma-separated list of Ant-style file patterns specifying files that must be excluded. No files are excluded when omitted. | -excludes=**/templates/**,**/**Test.** |
| rulesetfiles=FILENAMES | The path to the Groovy, XML or JSON RuleSet definition file(s). This can be a single file path, or multiple paths separated by commas. By default, the paths specified are relative to the classpath. But these paths may be optionally prefixed by any of the valid java.net.URL prefixes, such as “file:” (to load from a relative or absolute path on the filesystem), or “http:”. If it is a URL, its path may be optionally URL-encoded. That can be useful if the path contains any problematic characters, such as comma (‘,’) or hash (‘#’). For instance: “file:src/test/resources/RuleSet-,#.txt” can be encoded as: “file:src%2Ftest%2Fresources%2FRuleSet-%2C%23.txt” See URLEncoder\#encode(java.lang.String, java.lang.String). Defaults to “rulesets/basic.xml”. |
-rulesetfiles=rulesets/imports.xml,rulesets/naming.xml |
| ruleset=JSON_STRING | String containing a JSON ruleset content. The string must be URL-encoded in UTF-8 before being sent as argument to CodeNarc |
-rulesetfiles=rulesets/imports.xml,rulesets/naming.xml |
| report=REPORT-TYPE[:FILENAME|stdout] | The definition of the report to produce. The option value is of the form TYPE[:FILENAME|stdout], where TYPE is one of the predefined type names: “html”, “xml”, “text”, “json”, “console” or else the fully-qualified class name of a class (accessible on the classpath) that implements the org.codenarc.report.ReportWriter interface. And FILENAME is the filename (with optional path) of the output report filename. If the TYPE is followed by :stdout (e.g. html:stdout, json:stdout), then the report is written to standard out. If the report filename is omitted, the default filename for the report type is used (“CodeNarcReport.html” for “html”, “CodeNarcXmlReport.xml” for “xml”, “CodeNarcJsonReport.json”). If no report option is specified, default to a single “html” report with the default filename. |
-report=html -report=html:MyProject.html -report=xml -report=xml:MyXmlReport.xml -report=org.codenarc.report.HtmlReportWriter |
| maxPriority1Violations=MAX | The maximum number of priority 1 violations allowed (int). | -maxPriority1Violations=0 |
| maxPriority2Violations=MAX | The maximum number of priority 2 violations allowed (int). | -maxPriority2Violations=0 |
| maxPriority3Violations=MAX | The maximum number of priority 3 violations allowed (int). | -maxPriority3Violations=0 |
| title=REPORT TITLE | The title for this analysis; used in the output report(s), if supported by the report type(s). Optional. | -title=”My Project” |
| plugins | The list of CodeNarcPlugin class names to register, separated by commas. Optional. | -plugins=org.acme.MyPlugin,org.acme.MyOtherPlugin |
| help | Display the command-line help. If present, this must be the only command-line parameter. | -help |
Make sure that the following are included your CLASSPATH:
The Groovy jar
The CodeNarc jar
The SLF4J api/implementation jars, e.g. Logback.
The directories containing (or relative to) CodeNarc config files such as “codenarc.properties” or ruleset files.
The CodeNarc command-line application sets an exit status of zero (0) if the command successfully executes, and an exit status of one (1) if an error occurs executing CodeNarc, or if an invalid command-line option is specified.
Here is an example BAT file for running CodeNarc on Windows. It assumes the jars are in the current directory.
@set GROOVY_JAR="groovy-all-2.4.15.jar"
@set CODENARC_JAR="CodeNarc-1.6.1.jar"
@set SLF4J_JAR="slf4j-api-1.7.25.jar"
java -classpath $GROOVY_JAR;$CODENARC_JAR;$SLF4J_JAR org.codenarc.CodeNarc %*
Here is the equivalent Linux command.
export GROOVY_JAR="groovy-all-2.4.15.jar"
export CODENARC_JAR="CodeNarc-1.6.1.jar"
export SLF4J_JAR="slf4j-api-1.7.25.jar"
java -classpath $GROOVY_JAR:$CODENARC_JAR:$SLF4J_JAR org.codenarc.CodeNarc $*
Here is an example Gradle script to run CodeNarc using its command-line interface. It assumes that there is a codenarc.ruleset ruleset file in the current directory.
apply plugin: 'groovy'
repositories {
mavenCentral()
}
dependencies {
compile 'org.codenarc:CodeNarc:1.6.1'
compile 'ch.qos.logback:logback-classic:1.2.3'
}
task runCodeNarc(type:JavaExec) {
main = "org.codenarc.CodeNarc"
classpath = sourceSets.main.runtimeClasspath
args "-rulesetfiles=file:codenarc.ruleset"
}
