How to add a local non-maven project as a dependency for a maven project?

Question

I created a new Spring web app, and I\'d very much like to use Maven to handle builds/dependencies. My problem is that the project depends on some existing local projects,

This answer's a tad late but just in case somebody needs it, I found the solution using Maven's Build Helper Plugin, that is if you don't want deploying your non-maven project as a jar:

So basically you just add the source directory of the non-maven project in the tag:

    org.codehaus.mojo
    build-helper-maven-plugin
    3.0.0
    
        
            add-source
            generate-sources
            
                add-source
            
            
                
                    C:\Users\user123\eclipse-workspace\my_non_maven_project\src
                
            
        
    

Now if that non-maven project has dependencies of its own, you need to add them in the section of your maven project as well.
