Allow user to selectively not apply task to check task about ktlint-gradle

[JLLeitschuh]

Alternative suggestion that I just thought of (I could be swayed either way on this one):
Create a separate plugin (under the same repository (and maybe even under the same source directory)) that is called something like ktlint-helpers. This helpers plugin is automatically applied when you apply the ktlint plugin but when you only apply the ktlint-helpers plugin you only get the tasks that don't modify the check task.

@Tapchicoma, what are your thoughts?

Tough question, you have very specific use-case here.

Regarding option one:

ktlint {
    automaticallyAddToCheckTask = false
}

Then also there should be a flag for format tasks.

Regarding option two - conceptually I like it more, then the first one. From implementation wise - not sure how to approach it. Like add that ktlint plugin depends on ktlint-helpers plugin?

Can you archive the same goal by using Gradle property switch?

if (project.hasProperty("KtLint")) {
    apply plugin: "org.jlleitschuh.gradle.ktlint"
    ...
}

and then whoever is needed this task can run it using following:

$ ./gradlew -PKtLint ktlintApplyToIdea

That last option you proposed seems very "not gradley". I'm going to take a crack at my second plugin option and see how that works.

@JLLeitschuh do you want to keep this issue opened after 5.0.0 release?

Otherwise, please, close it.
