Javascript and CSS files combining in Maven build WITHOUT compression, minification etc

Make the following changes to your project:

1. In your pom.xml, <dependencies> tag, place:

   <!-- JAVASCRIPT COMBINATION -->
   <dependency>
       <groupId>ro.isdc.wro4j</groupId>
       <artifactId>wro4j-core</artifactId>
   </dependency>
   

2. In your pom.xml, <plugins> tag, place:

   <plugin>
       <groupId>ro.isdc.wro4j</groupId>
       <artifactId>wro4j-maven-plugin</artifactId>
       <version>1.4.3</version>
       <executions>
           <execution>
               <phase>process-resources</phase>
               <goals>
                   <goal>run</goal>
               </goals>
           </execution>
       </executions>
       <configuration>
           <targetGroups>allDev</targetGroups>
           <destinationFolder>${basedir}/src/main/webapp/</destinationFolder>
           <contextFolder>${basedir}/src/main/webapp/</contextFolder>
       </configuration>
   </plugin>
   

3. In your pom.xml (or the parent pom.xml) <dependencyManagement> tag, place:

   <!-- JAVASCRIPT COMBINATION -->
   <dependency>
       <groupId>ro.isdc.wro4j</groupId>
       <artifactId>wro4j-core</artifactId>
       <version>1.8.0</version>
   </dependency>
   

4. Create a wro.xml under /project/src/main/webapp/WEB-INF and place something like the following:

   <?xml version="1.0" encoding="UTF-8"?>
   <groups xmlns="http://www.isdc.ro/wro">  
       <group name="allDev">  
           <js minimize="false">/my1stJsFolder/*.js</js>
           <js minimize="false">/my2ndJsFolder/*.js</js>
           <js minimize="false">/someFileDirectlyUnderWEBINF.js</js>
       </group>
   </groups>  
   

5. In web.xml insert:

   <filter>
       <filter-name>WebResourceOptimizer</filter-name>
       <filter-class>ro.isdc.wro.http.WroFilter</filter-class>
   </filter>
   <filter-mapping>
       <filter-name>WebResourceOptimizer</filter-name>
       <url-pattern>/wro/*</url-pattern>
   </filter-mapping>
   

allDev.js will be generated under /project/src/main/webapp.

I am not sure yet how I could tell wro4j to only generate one in target (now you have two - one in the project source files and one in target).

When compressing with yui plugin I only get one in target. But this should not be that big of a problem for you.

ADDITIONALLY:

If you have any problems with the resource processing try adding to <build> tag:

<resources>
    <resource>
        <directory>src/main/resources</directory>
        <filtering>true</filtering>
    </resource>
</resources>

And also to <plugins> add

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <configuration>
        <nonFilteredFileExtensions>
            <nonFilteredFileExtension>pdf</nonFilteredFileExtension>
            <nonFilteredFileExtension>swf</nonFilteredFileExtension>
            <nonFilteredFileExtension>jpg</nonFilteredFileExtension>
            <nonFilteredFileExtension>jpeg</nonFilteredFileExtension>
            <nonFilteredFileExtension>class</nonFilteredFileExtension>
            <nonFilteredFileExtension>jks</nonFilteredFileExtension>
            <nonFilteredFileExtension>exe</nonFilteredFileExtension>
            <nonFilteredFileExtension>wmv</nonFilteredFileExtension>
            <nonFilteredFileExtension>jar</nonFilteredFileExtension>
            <nonFilteredFileExtension>zip</nonFilteredFileExtension>
            <nonFilteredFileExtension>gz</nonFilteredFileExtension>
        </nonFilteredFileExtensions>
    </configuration>
</plugin>
