Meet detekt, a static code analysis tool for the Kotlin programming language. It operates on the abstract syntax tree provided by the Kotlin compiler.

[detekt in action](docs/images/detekt_in_action.png "detekt in action")

Features

  • Code smell analysis for your Kotlin projects
  • Complexity reports based on lines of code, cyclomatic complexity and amount of code smells
  • Highly configurable rule sets
  • Suppression of findings with Kotlin's @Suppress and Java's @SuppressWarnings annotations
  • Specification of quality gates which will break your build
  • Code Smell baseline and whitelisting for legacy projects
  • Gradle plugin for code analysis via Gradle builds
  • Gradle tasks to use local IntelliJ distribution for formatting and inspecting Kotlin code
  • SonarQube integration
  • Extensibility by enabling incorporation of personal rule sets, FileProcessListener's and OutputReport's
  • IntelliJ integration
  • Unofficial Maven plugin by Ozsie

Quick Start ...

with the command-line interface

```shell script git clone https://github.com/arturbosch/detekt cd detekt ./gradlew build shadowJar java -jar detekt-cli/build/libs/detekt-cli-[version]-all.jar --help


#### with Gradle

Gradle 5.0+ is required:

```kotlin
buildscript {
    repositories {
        jcenter()
    }

    // or

    mavenCentral()
    jcenter {
        content {
            // just allow to include kotlinx projects
            // detekt needs 'kotlinx-html' for the html report
            includeGroup "org.jetbrains.kotlinx"
        }
    }
}

plugins {
    id("io.gitlab.arturbosch.detekt").version("[version]")
}

detekt {
    failFast = true // fail build on any finding
    buildUponDefaultConfig = true // preconfigure defaults
    config = files("$projectDir/config/detekt.yml") // point to your custom config defining rules to run, overwriting default behavior
    baseline = file("$projectDir/config/baseline.xml") // a way of suppressing issues before introducing detekt

    reports {
        html.enabled = true // observe findings in your browser with structure and code snippets
        xml.enabled = true // checkstyle like format mainly for integrations like Jenkins
        txt.enabled = true // similar to the console output, contains issue signature to manually edit baseline files
    }
}

tasks {
    withType<Detekt> {
        // Target version of the generated JVM bytecode. It is used for type resolution.
        this.jvmTarget = "1.8"
    }
}

See bintray for releases and artifactory for snapshots.

Adding more rule sets

detekt itself provides a wrapper over KtLint as a formatting rule set which can be easily added to the Gradle configuration:

dependencies {
    detektPlugins "io.gitlab.arturbosch.detekt:detekt-formatting:[version]"
}

Likewise custom extensions can be added to detekt.
