Can’t enable gradle dependency management in web applications

Help/Discuss

I have a gradle web application, and developing in STS.

I found that there are “Web App librarories” and “Gradle Dependencies” under my project, both of them have the same collection of jar files.

And it throw error in the end related with jar libs are loaded twice. Click Here Look.

Why does STS behaved like this? this is a Bug?

If you have questions about STS, I guess you should ask Spring folks.
Or you switch over to Buildship, as STS is anyway going to die: Migration guide from STS Gradle to Buildship · eclipse/buildship Wiki · GitHub

Also how is that SO post in any way related?
It is some question about a Maven project and wrong java CLI usage.
