Detekt: Autocorrect feature is not working

Question

I have included detekt (https://github.com/arturbosch/detekt/) in my project:

root build.gradle

buildscript {
    ext.kotlin_version = '1.3.50'
    ext.detekt_version = "1.0.1"
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "io.gitlab.arturbosch.detekt:detekt-gradle-plugin:$detekt_version"
    }
}

plugins {
    id("io.gitlab.arturbosch.detekt").version("1.0.1")
}

app build.gradle

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'io.gitlab.arturbosch.detekt'

android { // .. just defaults }

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    // ... other dependencies

    detekt "io.gitlab.arturbosch.detekt:detekt-formatting:$detekt_version"
    detekt("io.gitlab.arturbosch.detekt:detekt-cli:$detekt_version")

}

detekt {
    toolVersion = "$detekt_version"
    input = files("src/main/java")
    filters = ".*/resources/.*,.*/build/.*"
    config = files("../detekt/detekt-config.yml")
    reports {
        xml {
            enabled = true
        }
        html {
            enabled = true
        }
    }
}

Although I setted some rules with the attribute autoCorrect: true the code is not reformatted when I execute

./gradlew detekt

The analysis report is created and the issues are shown, but no auto correction has been made.

Answer 1

With 1.0 RC15 autoCorrect needs to be enabled in the gradle properties:

detekt {
    toolVersion = "$detekt_version"
    input = files("src/main/java")
    filters = ".*/resources/.*,.*/build/.*"
    config = files("../detekt/detekt-config.yml")
    autoCorrect = true
    reports {
        xml {
            enabled = true
        }
        html {
            enabled = true
        }
    }
}

From https://detekt.github.io/detekt/changelog-rc.html#rc15

Cli/Gradle Plugin: autoCorrect inside the yaml config was removed. Please use the --auto-correct cli flag or autoCorrect detekt extension property in the Gradle plugin.
