В чем смысл «<<<", "> >>» и «---» в выводе maven?

Некоторые линии приставкой и суффиксом «< < <», некоторые с «>>>», а некоторые с «---». Что они имеют в виду?

Answer 1

--- представляет выполнение цели плагина Maven, за исключением следующего.

>>> представляет выполнение цели плагина Maven, которая развивает собственный жизненный цикл.

<<< обозначает конец разветвленного жизненного цикла.
