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

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

Make the following changes to your project:
In your pom.xml, <dependencies> tag, place:
<!-- JAVASCRIPT COMBINATION -->
<dependency>
<groupId>ro.isdc.wro4j</groupId>
<artifactId>wro4j-core</artifactId>
</dependency>
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>
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>
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>
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>

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

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:
