Enable SASS/LESS preprocessor support for Spring Boot projects with JAR packaging

[AlexFalappa]

It would be nice to enable NetBeans SASS/LESS preprocessing support on files in the src/main/resources/static folder.

See #46 for some findings made by @janScheible on this matter

Thank you @AlexFalappa for your answer and for opening that new issue.

1. Changing packaging type to war works (thanks to http://hg.netbeans.org/main-silver/rev/306e875d1344) but is not the desired solution. jar packaging is the real beauty of Spring Boot. ;-)
2. Current workaround is to use the LESS Maven plugin

   <plugin>
    <groupId>org.lesscss</groupId>
    <artifactId>lesscss-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>less-compile</id>
        </execution>
    </executions>
    <configuration>
        <sourceDirectory>${project.basedir}/src/main/transient-resources/less</sourceDirectory>
        <outputDirectory>${project.basedir}/src/main/resources/static/css</outputDirectory>
        <compress>true</compress>
        <includes>
            <include>main.less</include>
        </includes>
    </configuration>
   </plugin>
   

   together with a Netbeans action like

   <action>
    <actionName>CUSTOM-LESS Compile (Watch)</actionName>
    <displayName>LESS Compile (Watch)</displayName>
    <goals>
        <goal>lesscss:compile</goal>
    </goals>
    <properties>
        <lesscss.watch>true</lesscss.watch>
    </properties>
   </action>
   

3. I would be happy if anybody could give me some pointers how to implement this ticket. I simply have no experience with developing Netbeans plugins but I'm eager to know more. :-)
