This isn't unique to continuous build.
A task that modifies its own inputs will never be considered up-to-date when run "normally" without continuous build.

If your build enters a build cycle like this, you can track down the task by looking at the list of files reported changed by Gradle.
After identifying the file(s) that are changed during each build, you should look for a task that has that file as an input.

        name == "first"
        tracker.root
        tracker.segments.empty
        tracker.toRelativePath() == ""
    }

    def "can enter and leave second level"() {
        given:
        tracker.enter("root")
        tracker.enter("first")
        when:
        tracker.enter("second")
        then:
        !tracker.root
        tracker.segments as List == ["first", "second"]
