rt.jar seems part of java 8 and you're probably running this with java 11. This library seems does not support java 11 yet.

(...) this determines what version of a dependency will be used when multiple versions of an artifact are encountered. (...) You can always guarantee a version by declaring it explicitly in your project's POM. (...) since Maven 2.0.9 it's the order in the declaration that counts: the first declaration wins.

suspend=y - ждать ли

тут еще есть фича что ждать от любого хоста подключение: address=*:5005

когда -Drun.jvmArgumanets="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=y,address=5005" не работает.

так работает:

тут ждет пока не подрубится слушательк сокету - почему так? mvn это отдельный процесс и он ждет подключения IDE перед тем как запустить spring-boot в пакете. а когда run.jvmArgumants там другое сообщение и не ждет внешних подключений.
