CoffeeScript compilation in Maven project

There are three available Maven plugins:

• talios / coffee-maven-plugin
• iron9light / coffeescript-maven-plugin
• jakewins / brew

Brew works and has a lot of features, but unfortunately it is not supported yet.

Coffescript-maven-plugin works only with Java version 7, what in our case is not applicable.
Coffee-maven-plugin by talios has been recently updated und works fine with Maven 3 and Java 6.

Lets look, how to activate Coffescript compilation in our project:

      <plugin>
        <groupId>com.theoryinpractise</groupId>
        <artifactId>coffee-maven-plugin</artifactId>
        <version>1.4.7</version>
        <configuration>
          <coffeeDir>${basedir}/src/main/webapp/js/coffee</coffeeDir>
          <coffeeOutputDirectory>${basedir}/src/main/webapp/js</coffeeOutputDirectory>
        </configuration>
        <executions>
          <execution>
            <id>coffee</id>
            <goals>
              <goal>coffee</goal>
            </goals>
          </execution>
        </executions>
      </plugin>

To run it we need to execute next command:

$ mvn coffee:coffee
