javascript - Where is the require.js file generated from? -

i learning angular 2 example https://github.com/pkaul/maven-typescript-example

so after run 3rd step (mvn jetty:run), runnable war folder packaged in example-webapp/target folder. however, there 1 file not sure about. under folder example-webapp/target/example-webapp-0.1.0-snapshot/modules, require.js file, old timestamp 2013-05-14.

i know comes , for. guessing file related requirejs-maven-plugin plugin defined in pom.xml inside example-webapp. standing confirmed or corrected.

<plugin>     <groupid>com.github.mcheely</groupid>     <artifactid>requirejs-maven-plugin</artifactid>     <version>1.0.4</version>     <executions>         <execution>             <phase>package</phase>             <goals>                 <goal>optimize</goal>             </goals>         </execution>     </executions>     <configuration>         <skip>true</skip><!-- not enabled default -->         <configfile>${basedir}/src/build/js/optimize.js</configfile>         <filterconfig>true</filterconfig>     </configuration> </plugin> 

the file require.js being pulled maven dependency:

<dependency>   <groupid>org.jszip.redist</groupid>   <artifactid>require</artifactid>   <version>2.1.6</version>   <type>jszip</type> </dependency> 

the project uses jszip-maven-plugin handle javascript libraries if standard maven dependencies (like spring or else):

jszip's maven plugin used when want either create jszip modules or consume jszip modules in war project.

the big advantage of plugin instead of copying , downloading manually require.js file , putting in correct place of webapp, makes build automatic , easying updates (you need update dependency). goes hand-to-hand maven dependency concept traditional java libraries.

the plugin download javascript libraries maven central jszip, unpack them , put them configured:

<plugin>     <groupid>org.jszip.maven</groupid>     <artifactid>jszip-maven-plugin</artifactid>     <extensions>true</extensions>     <configuration>         <mappings>             <!-- copy jszip dependencies directory "modules" -->             <mapping>                 <select>*:*</select>                 <path>modules</path>             </mapping>         </mappings>     </configuration>     <!-- --> </plugin> 

in case, copied modules directory, see output. <select>*:*</select> means consider jszip dependencies , <path>modules</path> specifies output directory.

so actually, has nothing requirejs-maven-plugin there optimize , compress javascript files.
