We're extremely excited to share with you all the next upcoming stable release of Detekt: 1.20.0 🎉
This release is coming with 16 new rules, new API and functionalities and several stability improvements.

First, much thanks to our sponsors ❤️ as we were able to buy a domain and move our website to https://detekt.dev/.

As for the feature shipped, we work a lot on the Reporting side: we added a new type of reporting, improved the styling of the existing one and
generally reduced the unnecessary warnings of run with type resolution.

For rules like ForbiddenMethod where you can configure a signature of a method you want to use in your rule, we added a new syntax
that allows to reference generic methods & extension functions.

We update a lot of the libraries we depend on bringing Detekt up to the ecosystem: KtLint 0.45.2, Kotlin 1.6.20 and Gradle 7.4.2 to name a few.

Finally, we also migrated all of our tests from Spek to JUnit. This was a huge effort that will hopefully make easier for contributors
to be involved with Detekt.

As always, we want to take the opportunity to thank our contributors for testing, bug reporting and helping
us release this new version of Detekt. You're more than welcome to join our community on the #detekt channel on KotlinLang's Slack (you can get an invite here).

Please welcome the next upcoming stable release of Detekt: 1.19.0 🎉
This release is coming with a lot of new features, new rules, evolution in the API and stability improvements.

Specifically, we've shipped some features that will allow you to better adapt detekt to run on codebases
that are using JetPack compose with features such as ignoreAnnotated and ignoreFunction.

As always, we want to take the opportunity to thank our contributors for testing, bug reporting and helping
us release this new version of Detekt. You're more than welcome to join our community on the #detekt channel on KotlinLang's Slack (you can get an invite here).

Notable Changes

• We now offer an ignoreAnnotated configuration key that you can use on all your rules to suppress findings if inside an annotated block (e.g. @Composable) - #4102 and #4241
• Similarly, we now offer also an ignoreFunction configuration key that you can use to suppress findings if inside a function with a given name - #4148
• Report configuration is changing in the Gradle plugin. The reports extension on the detekt extension has been
  deprecated. See the Migration section below for steps to migrate to the new recommended configuration - #3687
• The ExplicitCollectionElementAccessMethod rule is now a type-resolution only rule - #4201
• The InvalidPackageDeclaration rule has been split to create the MissingPackageDeclaration rule - #4149
• The ForbiddenComment rule now offers a customMessage configuration key - #4126
• We bumped ktlint and updated the default enabled rules to mirror what ktlint is doing - #4179
• Added a new LambdaParameterNaming rule, to enforce a naming convention of parameter inside lambdas - #4147
• Added a new InjectDispatcher rule, to check if dispatchers are injectable - #4222
• Added a new ConsoleReport format - #4027
• Gradle: We added the --auto-correct cmdline option to gradle tasks - #4202
• Gradle: We removed the afterEvaluate wrapper from the Android and KMM plugin - #4159 and #4271
• We now test against Java 17 and stopped testing against Java 16 - #4136
• Remove library specific configurations like Jetpack Compose and Dagger from the default config - #4101
• Remove detekt-bom module - #4043
• Use reference in fallback property delegate - #3982

Migration

Configuring reports in the Gradle plugin should be done at the task level instead of at the extension (or global) level.
The previous recommendation resulted in the report output for multiple tasks overwriting each other when multiple detekt
tasks were executed in the same Gradle run.

Before this release the recommended way to configure reports was using the detekt extension:

detekt {
    reports {
        xml {
            enabled = true
            destination = file("build/reports/detekt/detekt.xml")
        }
    }
}

This meant all detekt tasks would output the report to the same destination. From this detekt release you should enable
and disable reports for all tasks using the withType Gradle method:

// Kotlin DSL
tasks.withType<Detekt>().configureEach {
    reports {
        xml.required.set(true)
    }
}

// Groovy DSL
tasks.withType(Detekt).configureEach {
    reports {
        xml.required.set(true)
    }
}

To customize the report output location configure the task individually:

tasks.detektMain {
    reports {
        xml {
            outputLocation.set(file("build/reports/detekt/customPath.xml"))
            required.set(true) // reports can also be enabled and disabled at the task level as needed
        }
    }
}

Migration

Configuring reports in the Gradle plugin should be done at the task level instead of at the extension (or global) level.
The previous recommendation resulted in the report output for multiple tasks overwriting each other when multiple detekt
tasks were executed in the same Gradle run.

Before this release the recommended way to configure reports was using the detekt extension:

detekt {
    reports {
        xml {
            enabled = true
            destination = file("build/reports/detekt/detekt.xml")
        }
    }
}

This meant all detekt tasks would output the report to the same destination. From this detekt release you should enable
and disable reports for all tasks using the withType Gradle method:

// Kotlin DSL
tasks.withType<Detekt>().configureEach {
    reports {
        xml.required.set(true)
    }
}

// Groovy DSL
tasks.withType(Detekt).configureEach {
    reports {
        xml.required.set(true)
    }
}

To customize the report output location configure the task individually:

tasks.detektMain {
    reports {
        xml {
            outputLocation.set(file("build/reports/detekt/customPath.xml"))
            required.set(true) // reports can also be enabled and disabled at the task level as needed
        }
    }
}

1.18.0 - 2021-08-12

We're more than excited to introduce you a next stable release of Detekt: 1.18.0 🎉
This release is coming with a lot of changes, new rules, evolution in the API and stability improvements.

We want to take the opportunity to thank our contributors for testing, bug reporting and helping
us release this new version of Detekt.

Notable Changes

• We've added two new rules: AvoidReferentialEquality and BooleanPropertyNaming (see #3924 and #3795)
• This version of Detekt ships with Kotlin 1.5.21, and we're compiling with apiVersion set to 1.4 - #3956 and #3852
• The minimum version of Gradle to use Detekt Gradle Plugin is now 6.1 - #3830
• This version of Detekt has been tested against Java 16 - #3698
• We fixed a long-standing bug related to parallel execution (#3248) - #3799 and #3822
• We now use multi-line format for list options in the default detekt config file - #3827
• The rule VarCouldBeVal has been updated and now works only with type resolution to provide more precise findings - #3880
• We removed all the references to Extensions.getRootArea that is now deprecated from our codebase. This was affecting users with sporadic crashes. - #3848
• For detekt rule authors: We created a Github Template that you can use to bootstrap your custom rule project: detekt-custom-rule-template. You can use JitPack to host it and share your rule easily with other members of the community.
• For detekt rule authors: We finished the rework to use the annotations instead of kdoc tags in rules. Specifically configurations must be configured using @Configuration while auto-correction capability should be specified with the @AutoCorrectable annotation #3820.

Migration

• We renamed the input property inside the detekt{} extension of the Gradle plugin to source. The input property has been deprecated, and we invite you to migrate to the new property (see #3951)

// BEFORE
detekt {
    input = files(...)
}

// AFTER
detekt {
    source = files(...)
}

• For all rule authors: When accessing a config value within a rule, using valueOrDefault and valueOrDefaultCommaSeparated is no longer recommended. While both will remain part of the public api, they should be replaced by one of the config delegates (see #3891). The key that is used to lookup the configured value is derived from the property name.

/* simple property */
// BEFORE
val ignoreDataClasses = valueOrDefault("ignoreDataClasses", true)
// AFTER
val ignoreDataClasses: Boolean by config(true)

/* transformed simple property */
// BEFORE
val ignoredName = valueOrDefault("ignoredName", "").trim()
// AFTER
val ignoredName: String by config("", String::trim)

/* transformed list property */
// BEFORE
val ignoreAnnotated = valueOrDefaultCommaSeparated("ignoreAnnotated", listOf("Inject", "Value"))
        .map(String::trim)
// AFTER
val ignoreAnnotated: List<String> by config(listOf("Inject", "Value")) { list -> 
    list.map(String::trim) 
}

• For all rule authors: The types ThresholdRule and LazyRegex have been marked as deprecated and will be removed in a future release. Please migrate to config delegates.

/* ThresholdRule */
// BEFORE
class MyRule(config: Config, threshold: Int = 10) : ThresholdRule(config, threshold) {
    // ...
}
// AFTER
class MyRule(config: Config) : Rule(config) {
    private val threshold: Int by config(10)
    // ...
}

/* LazyRegex */
// BEFORE
private val allowedPattern: Regex by LazyRegex("allowedPatterns", "")
// AFTER
private val allowedPattern: Regex by config("", String::toRegex)

• For custom rule authors: This will be the last version of detekt where we publish the detekt-bom artifact. This change should not affect anyone. If it affects you, please let us know.
