detekt/detekt v1.12.0

on GitHub

• 2020-08-25

Notable Changes

• Kotlin 1.4 support
• New rules: UseCheckNotNull, UseRequireNotNull, NonBooleanPropertyPrefixedWithIs
• The Gradle plugin now requires at least Gradle 5.4. This aligns with Kotlin's Gradle plugin.
• The Gradle plugin now supports configuration avoidance
• The Gradle plugin now generates additional detekt tasks for Android projects
• KtLint 0.38.1 support (via detekt-formatting)

Migration

• ArrayPrimitive rule is more precise but requires type resolution now.
• The deprecated customReports property of the Gradle plugin got removed.
• Deprecated properties xmlReportFile, htmlReportFile, txtReportFile are now internal.

Note the default gradle detekt task does not run over test sources.
To include test sources following setup can be used:

detekt {
    // ...
    input = objects.fileCollection().from(
        "src/main/java",
        "src/test/java",
        "src/main/kotlin",
        "src/test/kotlin"
    )
}

This does not apply to gradle detektTest.
We encourage to also check test sources.
We will include test sources by default in detekt 1.15.0 or later.
