I tried searching on Google about these and cant really find any thing. 

mvn --define : what does it do, how can i use it and for what?

in the maven-compiler-plugin entry (in my POMs) I added 

```
 <*verbose>true<*/verbose>

```

I added it to see if it prints out the JAVA\_HOME but when i ran the mvn install (in my project directory) but nothing extra ordinary came out as a verbose for compile (just warnings that were coming before as well) even mvn clean compile doesn't give me anything. is there an option to echo the JAVA\_HOME when doing compile?
