Java Code Examples for org.gradle.api.artifacts.result.ResolvedComponentResult#getDependencies()

/**
 * Traverses the dependency tree post-order and collects dependencies.
 * <p>
 * The recursive post-order traversal returns the root of the (sub)tree.
 * This allows the post-order adding into the set of dependencies as we
 * return from the recursive calls. The set of seen dependencies ensures
 * ensures that the cycles in Ivy metadata do not cause cycles in our
 * recursive calls.
 *
 * @param root         the root of the dependency (sub)tree
 * @param seen         the input set of already seen dependencies
 * @param dependencies the output set of dependencies in post-order
 * @return the root itself
