Cannot choose between the following variants of com.pinterest:ktlint:0.41.0

[nuhkoca]

I have upgraded ktlint from 0.40.0 to 0.41.0. However, I am getting below error when I run ./gradlew ktlintCheck. There is no change in my config between two versions. How do I fix this? Thank you.

Sorry, since it is a private repo, I am posting the relative parts here.

• ktlint-gradle plugin version: 10.0.0
• Gradle: 6.8.3
• Android Studio: 4.1.3

Wild guess - do you have mavenCentral() repo in repositories { .. } block?

For me using KtLInt 0.41.0 works ok with this plugin, so would be nice to provide some repo reproducing this issue.

[nuhkoca]

@Tapchicoma yes we do have mavenCentral(). I think I have found the problem. As far as I se, it is originating from explicit definition of ktlint version inside ktlint block. For instance;

This works;

ktlint {
  android = true
}

This doesn't work;

ktlint {
  android = true
  version = "0.41.0"
}

Created a sample repo for you: https://github.com/nuhkoca/ktlint-sample

[Tapchicoma]

I see that running ./gradlew :app:ktlintCheck task completes with KtLint errors. It is only the root project ktlintCheck fails 🤔

Doing this diff solves the issue:

Generally it is not advised to use mix of old classpath approach and new plugin api - check second question in faq.

Though changing in sample project ktlint-gradle plugin to use old classpath approach does not fix the initial issue, so this is the bug.

[nuhkoca]

@Tapchicoma yes, using the new plugin api fixes this issue. However, I am not sure I can do these changes in the private repo immediately. As of now, all plugins are placed into the buildscript. Please let me know when you have a fix for this. Thank you!

[nuhkoca]

@Tapchicoma seems, we have an answer here

What do you think of it? Could it be feasible in the plugin in the near future?

[Tapchicoma]

@nuhkoca to workaround the issue you could temporary add following code into build.gradle:

configurations.named("ktlint").configure {
    resolutionStrategy {
        dependencySubstitution {
            substitute module("com.pinterest:ktlint") with variant(module("com.pinterest:ktlint:0.41.0")) {
                attributes {
                    attribute(Bundling.BUNDLING_ATTRIBUTE, objects.named(Bundling, Bundling.EXTERNAL))
                }
            }
        }
    }
}

[nuhkoca]

Thank you @Tapchicoma I'll do it as a workaround for now. So will you fix this this in the next release?

[Tapchicoma]

Will be included into #459 PR.

[BraisGabin]

If someone want the workaroud using Kotlin DSL:

configurations.named("ktlint").configure {
    resolutionStrategy {
        dependencySubstitution {
            substitute(module("com.pinterest:ktlint")).with(variant(module("com.pinterest:ktlint:0.41.0")) {
                attributes {
                    attribute(Bundling.BUNDLING_ATTRIBUTE, objects.named(Bundling::class, Bundling.EXTERNAL))
                }
            })
        }
    }
}
