Provides a convenient wrapper plugin over the ktlint project.
This plugin can be applied to any project but only activates if that project has the kotlin plugin applied. The assumption being that you would not want to lint code you weren't compiling.
This plugin was written using the new API available for gradle script kotlin builds. This API is available in new versions of gradle.
Minimal supported Gradle version: 4.3
Minimal supported ktlint version: 0.10.0
Build script snippet for use in all Gradle versions:
buildscript {
repositories {
maven {
url "https://plugins.gradle.org/m2/"
}
}
dependencies {
classpath "gradle.plugin.org.jlleitschuh.gradle:ktlint-gradle:4.1.0"
}
}
apply plugin: "org.jlleitschuh.gradle.ktlint"
Build script snippet for new, incubating, plugin mechanism introduced in Gradle 2.1:
plugins {
id "org.jlleitschuh.gradle.ktlint" version "4.1.0"
}
Optionally apply plugin to all project modules:
subprojects {
apply plugin: "org.jlleitschuh.gradle.ktlint" // Version should be inherited from parent
}
The following configuration block is optional.
If you don't configure this the defaults defined in the KtlintExtension object will be used. The version of Ktlint used by default may change between patch versions of this plugin. If you don't want to inherit these changes then make sure you lock your version here.
ktlint {
version = ""
debug = true
verbose = true
android = false
outputToConsole = true
reporters = ["PLAIN", "CHECKSTYLE"]
ignoreFailures = true
ruleSets = [
"/path/to/custom/rulseset.jar",
"com.github.username:rulseset:master-SNAPSHOT"
]
}
Check samples folder that provides examples how-to apply plugin.
This plugin adds two tasks to every source set: ktlint[source set name]Check
and ktlint[source set name]Format
.
Additionally, a simple ktlintCheck
task has also been added that checks all of the source sets for that project.
Similarly, a ktlintFormat
task has been added that formats all of the source sets.
If project has subprojects - plugin also adds two meta tasks ktlintCheck
and ktlintFormat
to the root project that
triggers related tasks in subprojects.
Two another tasks added:
ktlintApplyToIdea
- Task generates IntelliJ IDEA (or Android Studio) Kotlin style files in project.idea/
folder.ktlintApplyToIdeaGlobally
- Task generates IntelliJ IDEA (or Android Studio) Kotlin style files in user home IDEA (or Android Studio) settings folder.
They are always added only to the root project.
Note that this tasks will overwrite the existing style file.
Import the settings.gradle.kts file into your IDE.
To enable Android sample either define ANDROID_HOME
environmental variable or
add local.properties
file to project root folder with following content:
sdk.dir=<android-sdk-location>
Building the plugin: ./plugin/gradlew build
Running current plugin snapshot check on sample projects: ./gradlew ktlintCheck
