Unlike IDEA, which has options for using existing sources, STS is not like options for using an existing project. I do not want to create new project source folders and bin folders. I already have a Maven POM, and I want STS to just use this. How can I do this without ruining my existing project?
thanks
Could you try to do "File / Import", you should see this entry in the menu:
If this is a maven project that you can import using POM ("Maven Projects"), if it is an eclipse project, you can use "Existing projects in the workspace".
