Couldn't add dependency to pom.xml

Question

I coudn't add new dependency to pom.xml.

My steps :

1. I use Spring Template Project MVC.
2. Open in Eclise pom.xml.
3. Open "Dependency" tab.
4. Add my required dependency: spring-tx.
5. Save my changes. But my changes didn't affect Dependency "Hierarchy" and "Effective POM" tabs.
6. Clean and Build Project. In my pom.xml dependency spring-tx disappeared. So my problem still here.

How can I add dependency to pom.xml and save it into when project Build?

Answer 1

Or next time, you can use any file editor to add the dependencies. Highly recommend Notepad++.

Answer 2

Use the pom "editor" tab instead.
