How to achieve deployment while saving a multi-module Maven project in NetBeans?

I have a multi-module Maven project in NetBeans with the following structure on the file system.

.
| MyProject/
├── web-module/
|   ├── src/
|   └── pom.xml
├── core-module/
|   ├── src/
|   └── pom.xml
└── pom.xml

      

        
        
        
      

    

I set Compile on Save on all modules and Deploy on Save in the web module, and now when I change something in the web module it is automatically compiled and deployed, but it doesn't work for changes in the main module. I also created a new project group (files / project groups ... / Projects and all required projects) and set the parent project there, but it also doesn't work.

My questions:

• Is it possible at all to achieve what I want in NetBeans, and if yess, how?
• Deploy on Save in NB seems to restart Tomcat which is not an efficient solution (Spring context load time) - can something like "jvm hot swap" be used, namely when I made some changes (I mean changes inside the method without changing the class structure), I would like to see this immediately without restarting Tomcat.

I am using NetBeans 8, Maven built in NB and Tomcat 6

PS. I know what I want to achieve, this is not rocket science, I was able to configure Eclipse this way and everything worked decently (without installing any additional plugins).

PPS. Yes, I've heard about JRebel, but it's not free.
