RC15

Migration

Cli: filters concept got deprecated and removed. Please use the new excludes and includes options. excludes works exactly like filters did except it takes now a comma separated list of globing patterns instead of a regular expressions. For example --filters .*/resources/.* becomes --excludes **/resources/**. includes also accepts globing patterns. Globing patterns allow us to reuse some common logic of the java.nio.file package which for example handle Windows specific paths for us. This change also allows to be more fine granular with analyzing files: --excludes **/generated/** --includes **/generated/this-needs-to-be-checked. The following how-to guide describes the migration process from the test-pattern functionality.
Gradle Plugin: Including or excluding paths and files from detekt scanning is now done by setting include & exclude on the detekt task which aligns with how other static analysis tools handle filters. Any use of filters will be ignored. See custom task examples for Groovy and Kotlin. For details of syntax see https://docs.gradle.org/current/javadoc/org/gradle/api/tasks/util/PatternFilterable.html
Gradle Plugin: Adds support for TXT report.
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.

RC10

Migration

The configurations in the Detekt Gradle Plugin have changed to align the Plugin further with other static analysis plugins. Similar to FindBugs the Detekt Gradle Plugin now defines two configurations: detekt and detektPlugins.

detekt is now used to define detekt dependencies such as the detekt-cli.
detektPlugins is used to define custom detekt RuleSets and rules such as the detekt-formatting rules

To define custom detekt extensions or to add the detekt-formatting rules you will now have to define them as:

dependencies {
    detektPlugins("io.gitlab.arturbosch.detekt:detekt-formatting:[version]")
    detektPlugins("your.custom.detekt.rules:rules:[version]")
}

The report id plain has been renamed to txt. If you were using --report "plain:/tmp/plaintxt" before it's now --report "txt:/tmp/plaintxt".

The --filters argument no longer checks on the absolute path of files, but rather relative paths to the project root.

The published url changed slightly. So users using the old way of applying plugins need to change their gradle setup:

buildscript {
  repositories {
    jcenter()
    maven { url "https://plugins.gradle.org/m2/" }
  }
  dependencies {
    // https://mvnrepository.com/artifact/gradle.plugin.io.gitlab.arturbosch.detekt/detekt-gradle-plugin 
    // for version <= 1.0.0.RC9.2
    classpath "gradle.plugin.io.gitlab.arturbosch.detekt:detekt-gradle-plugin:[version]"
    // https://mvnrepository.com/artifact/io.gitlab.arturbosch.detekt/detekt-gradle-plugin?repo=gradle-plugins
    // for version >= 1.0.0-RC10
    classpath "io.gitlab.arturbosch.detekt:detekt-gradle-plugin:[version]"
  }
}

apply plugin: "io.gitlab.arturbosch.detekt"

RC9

Migration

You need Gradle 4.9 or higher to migrate to RC9.

With RC9, which is the last major release candidate before 1.0.0, a new gradle plugin gets introduced. The detekt extension configuration changes a bit and the concept of profiles was removed. There is no detektCheck task anymore, just a detekt task which is incremental and is bound to the check task. Now the detekt plugin must be applied to every project and just analyzes Kotlin files in the source set of this project.

An important change is that detekt-gradle-plugin does not pull the latest version which is found online but has a hardcoded version by default. This can break your current setup if you have not specified a version = "..."" property! Furthermore this version property got now removed and the new toolVersion property is used to specify the underlying detekt tool version. This was done to be inline with other static analysis tools.

Instead of writing

detekt {
    defaultProfile { // or profile("main") {...}
        // properties
    }
}

we now write

detekt {
    // properties
}

If we want all our sub projects to get analyzed by detekt, something like

subprojects {
   detekt {
       // properties
   }
}

can be applied to the root build file.

A full detekt configuration for multi-module gradle project could look like detekt's own build file. Attention(!) this must be translated to Groovy if you do not use the Kotlin DSL. See this page for reference.

plugins {
    id("io.gitlab.arturbosch.detekt") version "[1.0.0.RC9]"
}
...
subprojects {
    ...
    apply {
        plugin("io.gitlab.arturbosch.detekt")
        ...
    }

    val userHome = System.getProperty("user.home")

    detekt {
        debug = true
        toolVersion = usedDetektVersion
        config = files(
                project.rootDir.resolve("detekt-core/src/main/resources/default-detekt-config.yml"),
                project.rootDir.resolve("reports/failfast.yml")
        )
        filters = ".*/resources/.*,.*/build/.*"
        baseline = project.rootDir.resolve("reports/baseline.xml")

        reports {
            xml.enabled = true
            html {
                enabled = true
                destination = project.rootDir.resolve("reports/detekt.html")
            }
        }

        idea {
            path = "$userHome/.idea"
            codeStyleScheme = "$userHome/.idea/idea-code-style.xml"
            inspectionsProfile = "$userHome/.idea/inspect.xml"
            report = "project.projectDir/reports"
            mask = "*.kt"
        }
}

Make sure that all properties expecting a path expect a FileCollection or a File type now. The config property now explicitly tells the user that detekt can consume multiple configuration yaml files (config = files(...)).

There is also a breaking change for the detekt-cli module which will attack custom gradle task and cli users. The output and reports options are no longer. There is the new --report option which can be used multiple times to generate specific reports. The report pattern now is --report [report-id:path-to-store-report]. There are three provided output reports named: plain, xml and html. Custom reports can be added to leveraging the detekt extension mechanism as described on the website.

- ConstantNaming got removed
- TopLevelPropertyNaming and ObjectPropertyNaming was added
- there are now configuration parameters for private properties

  VariableNaming:
    active: true
    variablePattern: '[a-z][A-Za-z0-9]*'
    privateVariablePattern: '(_)?[a-z][A-Za-z0-9]*'
  ObjectPropertyNaming:
    active: true
    propertyPattern: '[A-Za-z][_A-Za-z0-9]*'
  TopLevelPropertyNaming:
    active: true
    constantPattern: '[A-Z][_A-Z0-9]*'
    propertyPattern: '[a-z][A-Za-z\d]*'
    privatePropertyPattern: '(_)?[a-z][A-Za-z0-9]*'

McCabe calculation was corrected and can now be slightly higher which can result in unexpected ComplexMethod findings.
Instead of using a pattern like .*/test/.* to filter test sources, you can now specify a test-pattern inside a configuration. This allows to turn off specific rules or rule sets for test sources.

Migration

CLI

No break just extra notification that you can pass now more than one configuration file within the --config and --config-resource parameters

This allows overriding certain configuration parameters in the base configuration (left-most config)

Gradle Plugin

the detekt extension is now aware of configuration profiles
non default or 'main' profile, needs to be specified like gradle detektCheck -Ddetekt.profile=[profile-name]

Instead of writing something like

detekt {
    version = "1.0.0.M11"
    input = "$project.projectDir/src"
    filters = '.*/test/.*'
    config = "$project.projectDir/detekt-config.yml"
    output = "$project.projectDir/output.xml"
    idea {
        path = "$userHome/.idea"
        codeStyleScheme = "$userHome/.idea/idea-code-style.xml"
        inspectionsProfile = "$userHome/.idea/inspect.xml"
        mask = "*.kt,"
    }
}

you have to put a profile-closure around the parameters

detekt {
    profile("main") {
        version = "1.0.0.M11"
        input = "$project.projectDir/src"
        filters = '.*/test/.*'
        config = "$project.projectDir/detekt-config.yml"
        output = "$project.projectDir/output.xml"
    }
    profile("test") {
        filters = ".*/src/main/kotlin/.*"
        config = "$project.projectDir/detekt-test-config.yml"
    }
    idea {
        path = "$userHome/.idea"
        codeStyleScheme = "$userHome/.idea/idea-code-style.xml"
        inspectionsProfile = "$userHome/.idea/inspect.xml"
        mask = "*.kt,"
    }
}

This allows you too configure detekt-rules specific for each module. Also allowing to have different configurations for production or test code.

suppress code smells which are false positives
generate a baseline of code smells if your project is already old and has many smells, so only new smells are shown in analysis (see 'Code Smell baseline and ignore list' in README)

Improvements

move formatting to own rule set project as formatting works great on my kotlin projects but line/column calculation from within PsiElements is wrong (!?)
OptionalUnit and -Semicolon should be auto correctable and moved to formatting
show progress while waiting for the analysis

See all issues at: https://gitlab.com/arturbosch/detekt/milestones/6

M5

Threat variables in object declarations as constants too - #67
Normalize file content prevents some exceptions inside Psi - #66
Fix an "Underestimated text length" problem inside Psi - #65
Filter top level members from LargeClass and EqualsWithHashCode rules, preventing NoSuchElementExceptions - #64

In this milestone the goal was to fully be able to analyze the Kotlin project. All rule sets (except formatting) successfully run now. Formatting needs some fixes as line and column values are sometimes not correctly determined by the AST.

One idea of mine is to threat formatting as an extern rule set and only allow auto correcting the source code without an report to skip line/column problem.
