Серверная часть упаковки Kotlin интерфейс с Maven

#spring-boot #maven #kotlin

Вопрос:

Я создаю простое приложение с полным стеком с помощью Kotlin Spring и React. Я следил за некоторыми учебными пособиями о том, как подключить бэкэнд и интерфейс (но с Java) с помощью плагина maven переднего плана. Я пытался заставить это работать для Котлина, но потерпел неудачу.

Это был мой оригинал pom.xml

After failing and realizing this may not work for Kotlin I tried switching to kotlin-maven-plugin and try the same principles but could not get the code to work correctly.
