Specifying resource directories

By default, maven will look for your project's resources under src/main/resources

Project
|-- pom.xml
`-- src
    `-- main
        `-- resources

However, all your resources may not be in src/main/resources. Thus, you'd have to specify those directories by adding the following to your pom.

<project>
 [...]
 <build>
   [...]
   <resources>
     <resource>
       <directory> [your folder here] </directory>
     </resource>
   </resources>
   [...]
 </build>
 [...]
</project>

So if your resources resides in my-resources 

Project
|-- pom.xml
`-- src
    `-- my-resources

you can specify that director by doing the following

   [...]
   <resources>
     <resource>
       <directory>src/my-resources</directory>
     </resource>
   </resources>
   [...]

Furthermore, you can have several directories by adding resource tags

   [...]
   <resources>
     <resource>
       <directory>resource1</directory>
     </resource>
     <resource>
       <directory>resource2</directory>
     </resource>
     <resource>
       <directory>resource3</directory>
     </resource>
   </resources>
   [...]
