ktlint 0.47.0 throwing error when using rules with prefix ij_kotlin

[4brunu]

Expected Behavior

I updated ktlint from version 0.46.1 to 0.47.0 and when using rules with prefix ij_kotlin it throws errors.

Here is my .editorconfig file.

# http://editorconfig.org
root = true

[*.{kt,kts}]
disabled_rules = filename

ij_kotlin_allow_trailing_comma = true
ij_kotlin_allow_trailing_comma_on_call_site = true

With the previous versions it was working.

I have updated ktlint from version 0.46.1 to 0.47.0 and it started throwing the following exception.
If I downgrade ktlint from version 0.47.0 to 0.46.1 it works again.

./gradlew ktlintFormat --daemon

Is it correct that you use the ktlint-gradle plugin? What version are you on?

In this commit the plugin has updated the default ktlint version from 0.42.1 to 0.43.2. As some breaking changes have been introduced in ktlint 0.47.x the communication between the ktlint-gradle plugin and ktlint might no longer work as expected and result in problems. It would be very helpful if you could try to reproduce the problem with the KtLint CLI. If you can reproduce with KtLint CLI than please post a code example and the exact command that you execute.

No, I'm using ktlint directly via gradle.

repositories {
    mavenCentral()
}

configurations {
    ktlint
}

dependencies {
    ktlint("com.pinterest:ktlint:0.46.1") {
        attributes {
            attribute(Bundling.BUNDLING_ATTRIBUTE, getObjects().named(Bundling, Bundling.EXTERNAL))
        }
    }
}

task ktlint(type: JavaExec, group: "verification") {
    description = "Check Kotlin code style."
    mainClass.set("com.pinterest.ktlint.Main")
    classpath = configurations.ktlint
    args "$project.rootDir/**/*.kt", "!**/build/generated/*", "--editorconfig=$qualityDir/ktlint/.editorconfig", "--reporter=html,output=$reportsDir/ktlint/ktlint.html"
    jvmArgs("--add-opens", "java.base/java.lang=ALL-UNNAMED")
    ignoreExitValue = true
}

check.dependsOn 'ktlint'

task ktlintFormat(type: JavaExec, group: "formatting") {
    description = "Fix Kotlin code style deviations."
    mainClass.set("com.pinterest.ktlint.Main")
    classpath = configurations.ktlint
    args "-F", "$project.rootDir/**/*.kt", "!**/build/generated/*", "--editorconfig=$qualityDir/ktlint/.editorconfig"
    jvmArgs("--add-opens", "java.base/java.lang=ALL-UNNAMED")
}

And then I call it via terminal ./gradlew ktlintFormat --daemon

[paul-dingemans]

There are a few possible causes for the problem. Please run both experiments below:

1. Refers variable $quality in --editorconfig parameter to an absolute or a relative url? Can you please try to remove the --editorconfig parameter entirely and put the '.editorconfig' file into you project directory?

2. Remove the globs $project.rootDir/**/*.kt, !**/build/generated/*.

[4brunu]

The issue is related to --editorconfig.

I tried to pass the absolute or the relative path of the .editorconfig file to the --editorconfig but it didn't work.

Then I removed the --editorconfig argument, and moved the .editorconfig file to the root project directory and it worked.

Here is my current gradle integration that works.

repositories {
    mavenCentral()
}

configurations {
    ktlint
}

dependencies {
    ktlint("com.pinterest:ktlint:0.47.0") {
        attributes {
            attribute(Bundling.BUNDLING_ATTRIBUTE, getObjects().named(Bundling, Bundling.EXTERNAL))
        }
    }
}

task ktlint(type: JavaExec, group: "verification") {
    description = "Check Kotlin code style."
    mainClass.set("com.pinterest.ktlint.Main")
    classpath = configurations.ktlint
    args "$project.rootDir/**/*.kt", "!**/build/generated/*", "--reporter=html,output=$reportsDir/ktlint/ktlint.html"
    jvmArgs("--add-opens", "java.base/java.lang=ALL-UNNAMED")
    ignoreExitValue = true
}

check.dependsOn 'ktlint'

task ktlintFormat(type: JavaExec, group: "formatting") {
    description = "Fix Kotlin code style deviations."
    mainClass.set("com.pinterest.ktlint.Main")
    classpath = configurations.ktlint
    args "-F", "$project.rootDir/**/*.kt", "!**/build/generated/*"
    jvmArgs("--add-opens", "java.base/java.lang=ALL-UNNAMED")
}

[paul-dingemans]

Ok cool. Are you working on Windows OS?

[4brunu]

No, I'm in macOS

[paul-dingemans]

Would you mind testing the fix with the latest snapshot? See https://pinterest.github.io/ktlint/install/snapshot-build/

[4brunu]

Hey, thanks for your help.
I have tested this and can confirm that it fixes the issue. 👍
