Spring plugin in Eclipse cannot open pom.xml

I've installed the most popular plugin in Eclipse (Spring Tools 4.14.1) and i tried to create a new project and open the pom.xml and then it shows error and comes like Failed to create the part's

stackoverflow.com

stack overflow를 참고해서 문제를 해결할 수 있었다.

Spring Tools 4.14.1 버전에서는 tm4e를 제공해주지 않기 때문에 따로 설치해주면 된다고 한다.

finish를 누른후 재시작하면 pom.xml이 정상적으로 보인다.
