Yet another coffeescript maven plugin.

Love coffeescript. Love Maven. Wanna replace javascript at all.

Just play with your .coffee like what you did to .js before, and let me take care of the rest:

• Compile (all or modified) coffeescript to javascript.
• Watch your changing (modify, create, delete, rename) and sync the javascript files at the same time.

There are two maven plugins can compile coffeescript to javascript, as I know:

• brew
• coffee-maven-plugin

brew can do more than just compile coffeescript, but it's not up to date, see here.

coffee-maven-plugin works great, but it is short of some features.

• Maven 2
• JDK 7

Just add the plugin to your pom:

<build>
  ...
  <plugins>
    ...
    <plugin>
      <groupId>com.github.iron9light</groupId>
      <artifactId>coffeescript-maven-plugin</artifactId>
      <version>1.1.2</version>
      <executions>
        <execution>
          <goals>
            <goal>compile</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

The full pom configuration is here. Configuration options shown are default values and can be ignored for normal use.

<build>
  <plugins>
    <plugin>
      <groupId>com.github.iron9light</groupId>
      <artifactId>coffeescript-maven-plugin</artifactId>
      <version>1.1.2</version>
      <configuration>
        <srcDir>${basedir}/src/main/webapp</srcDir>
        <outputDir>${basedir}/src/main/webapp</outputDir>
        <bare>false</bare>
        <modifiedOnly>false</modifiedOnly>
        <allowedDelete>true</allowedDelete>
        <compilerUrl></compilerUrl>
      </configuration>
      <executions>
        <execution>
          <id>coffeescript</id>
          <phase>generate-resources</phase>
          <goals>
            <goal>compile</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
</build>

mvn coffeescript:compile

Compile coffeescript files to javascript files.

• Requires a Maven project to be executed.
• Binds by default to the lifecycle phase: generate-resources.

• bare Boolean - Bare mode. Default value is: false.
• modifiedOnly Boolean - Only compile modified files. Default value is: false.
• outputDir File - Output Directory. Expression: ${basedir}/src/main/webapp
• srcDir File - Source Directory. Expression: ${basedir}/src/main/webapp
• compilerUrl String - CoffeeScript compiler file url. It supports both url string and file path string. e.g. http://coffeescript.org/extras/coffee-script.js or ${basedir}/lib/coffee-script.js

mvn coffeescript:watch OR mvn coffeescript:watch-mac

Compile coffeescript files to javascript files, and recompile as soon as a change occurs.

Note: the 'watch-mac' goal uses a drop-in replacement for the Java 7 WatchService because the official OSX WatchService implementation is broken.

• Requires a Maven project to be executed.

• allowedDelete Boolean - Delete javascript file when the coffeescript file deleted. Default value is: true.
• bare Boolean - Bare mode. Default value is: false.
• modifiedOnly Boolean - Only compile modified files. Default value is: false.
• outputDir File - Output Directory. Expression: ${basedir}/src/main/webapp
• srcDir File - Source Directory. Expression: ${basedir}/src/main/webapp
• compilerUrl String - CoffeeScript compiler file url. It supports both url string and file path string. e.g. http://coffeescript.org/extras/coffee-script.js or ${basedir}/lib/coffee-script.js
