Gradle: how do I inject a task dependency into a plugin-defined task?

If a plugin defines a series of tasks, is it possible to inject a dependency into these, such that the dependency is called before the plugin-defined task is executed?

The native-artifacts plugin defines buildNar (and buildNarxxx, where xxx is the platform config) tasks. It also defines extractNarDepsxxx (where xxx is the platform config for the Nar to be built). extractNarDeps is not called before builder, so the build fails as required dependencies are not downloaded prior to the attempted build.

How do I inject extractNarDepsxxx as a dependency into buildNarxxx?

Ok. Consider the following example:

apply plugin: 'java'

task someTask
task anotherTask

tasks.classes.mustRunAfter(anotherTask)
tasks.build.dependsOn(someTask)

There's a single plugin applied java and two custom tasks someTask and anotherTask.

Task build (taken from java plugin) dependsOn someTask. It means that when You run gradle build this task will be executed.

Task classes mustRunAfter anotherTask. So when You type gradle build anotherTask, anotherTask will run before build.

Try it. An ask further questions when needed.
