You can add resources in both main and test in your project. Add a text file in src/main/resources. Then you can access that via

	Reader ios = new InputStreamReader(getClass().getClassLoader().getResourceAsStream("file.txt"));		
	String s = IOUtils.toString(ios);
	System.out.println(s);

This is because the file.txt will be in target/classes/ now

In your test directory, you can put different resources there. A file in src/test/resources/ can be accessed via similar methods, but this time in the test java files.

You can also filter these resource files. That is, define a filter, which is a key value type file, which will be used to replace values in the resource file. Here's the default.properties in src/main/filters

	a.property=brilliant

Here's a test.xml in src/main/resources

	<some>${a.property}</some>

Now in our POM we need to define that the xml will be filtered

	...
	<build>
	<filters>
	  <filter>src/main/filters/default.properties</filter>
	</filters>    
	<resources>
	  <resource>
	    <directory>src/main/resources/</directory>
	    <filtering>true</filtering>
	  </resource>
	</resources>
	</build>
	...

If you mvn package this application the process-resources phase will be run, and you'll get this XML file in your target/classes/test.xml

	<some>brilliant</some>
