I want to wrote custom grade taks that “will be running” all of the static analysis checks at once - in my case it is detect, ktlint, android lint. These translates to below grade tasks:

./gradlew detektCheck
./gradlew ktlintCheck
./gradlew lint (this task does not exist gradle will select task from app module :app:lint)

As far I I know grade task can’t run another grade task and it can jus depend on another task (with makes perfect sense). Now I was able to write simple task (Kotlin Grade script) that runs detekt and ktlint checks (by using dependency mechanizm)

task("staticCheck") {
    dependsOn("detekt", "ktlintCheck")
}

Now I am struggling with adding the (Android) lint. I can’t simply add lint to dependencies (dependsOn("detekt", "ktlintCheck", "lint")) because lint task does not exists in configuration phase:

task("staticCheck") {
    val lintDependencies = subprojects.mapNotNull { it.tasks.findByName("lint") } //empty list

    doLast {
        val lintDependencies = subprojects.mapNotNull { it.tasks.findByName("lint") } //list containing few modules, however I can't use dependsOn here
    }
}

What is the best way of running all static analysis checks in single task?

Take a look at this issue: https://github.com/JLLeitschuh/ktlint-gradle/issues/55

Thanks to your advice I was able to achieve what I wanted

task("staticCheck") {
    afterEvaluate {
        val lintDependencies = subprojects.mapNotNull { "${it.name}:lint" }
        dependsOn(lintDependencies + listOf("ktlintCheck", "detekt"))
    }
}

The only issue now is that I am assuming that lint task is available in all modules (witch is not true for pure java modules) . I tried to retrieve list of lint tasks or plugin for module (subprojects.filter { it.plugins.hasPlugin(GradlePluginId.androidApplication) }) but in botch cases these variables are empty - like module would not be evaluated
