Maven asks you to organize your project by a standard directory layout. Although you can override the proposed structure via the project descriptor, conformance is strongly recommended.

At the top level there are only two directories: src and target. The target directory is used to house all output of the build. The src directory contains all of the source material for building the project, its site and so on.

The src directory contains a subdirectory for each type of resources:

• main for the main build artifact
  
• test for the unit test code
  
• site for your project site's documentation
  

This is the general layout:

Directory	Description
LICENSE.txt	Project's license
README.txt	Project's readme
pom.xml	The Maven "Project Object Model"
src/main/java	under which the normal package hierarchy exists
src/main/resources	the structure which is copied to the target classpath given the default resource definition
src/main/filters	Resource filter files
src/main/assembly	Assembly descriptors
src/main/config	Configuration files
src/main/webapp	Web application sources
src/test/java	Test sources
src/test/resources	Test resources
src/test/filters	Test resource filter files
src/site	Site
