Ignore specific dependencies

[tristanlins]

In some situations, dependency updates are irrelevant. For example, when developing a Gradle plugin and using the kotlin-dsl plugin, because the internal Gradle Kotlin version is used in that case.

Currently, however, all Kotlin updates are reported, even though you cannot change the version.

You can solve this with rejectVersionIf, for example, with the following condition:

(candidate.module.startsWith("org.gradle.kotlin.kotlin") ||
            candidate.group.startsWith("org.jetbrains.kotlin")) &&
            currentVersion != candidate.version

I don't know if it's possible to automatically determine that the internal Kotlin version should be used, but a filter could simplify this:

tasks.withType<DependencyUpdatesTask> {
    // if module is ignored, it will not be checked for updates
    ignoreModuleIf {
        candidate.module.startsWith("org.gradle.kotlin.kotlin") ||
            candidate.group.startsWith("org.jetbrains.kotlin")
    }

    // any ignored module will not be checked here
    ignoreVersionIf { ... }
}

Unfortunately, checkConstraints and checkBuildEnvironmentConstraints do not help here either.

Any suggestions?

It’s not the prettiest, but the most flexible approach is to use a custom report format to modify the results before printing them using our built-in ones.

Here is an example when I did this while a dependency had bad metadata on central. I moved it into the correct section until they got Sonatype’s help and fixed that. You could easily remove or otherwise adjust similarly.

Oh! And I do exactly your workaround for the kotlin dsl or force versions when newer are incompatible with my target jdk

I'm fine with the workaround as well. I thought maybe we could create a convenience method to make it easier.

Or even automatically determine that certain dependency reports are unnecessary. However, I currently don't see how that could work. Even though I have built one or two Gradle plugins, I'm not familiar with the details in the area of configurations 🙈.
