maven how to include dependencies correctly

I was trying to figuring out how to use maven but I didn't get it.

First I tried sqlite 3.8.7 from :

http://ift.tt/1xR8htX

I can compile well but when I try to execute maven doesn't find sqlite jar file, so I try to use :

mvn install:install-file

but It didn't work too, so I just used -cp and I have fixed.

Second I try to use jfreechart from :

http://ift.tt/1xR8htY

I did same steps below for jfreechart but this time it gives me NoClassDefFoundError.

Both of them works when I compile manually but with maven it's not. What I am missing about it ? If I always add manually like sqlite why should use maven anyway ?

Notes : I compile as :

mvn -compile

and I'm packaging as :

mvn -package

and finally I try to execute as :

java -cp target/porject.jar org.path.App

Edit :

This is for jfreechart app(pom.xml) I add dependency tags from mvnrepository.com

<project xmlns="http://ift.tt/IH78KX" xmlns:xsi="http://ift.tt/ra1lAU"
  xsi:schemaLocation="http://ift.tt/IH78KX http://ift.tt/VE5zRx">
  <modelVersion>4.0.0</modelVersion>

  <groupId>org.project</groupId>
  <artifactId>ChartTest</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>ChartTest</name>
