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

Question

Is there an Maven plugin that just combines js and css resources but doesn\'t do any minification, obsucation, compressing etc? Just simple resources concatenation.

Answer 1

I think most tools will allow you to turn off the minification.

Here is another couple that look interesting:

Looks about right :

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>  

Answer 4

I've used YUI Compressor for years. Used to do it in ANT, but there is also a maven plugin as well. The following link is an example for aggregation:
