Normal currently the less compiler command used is hard coded and doesn't allow additional compiler options if needed (see: lessc --help)
also provide option to customize the compiler command
e.g. in the pom
<configuration> <compileCommand>/my/custom/lessc</compileCommand> <!-- NEW --> <compileCommandOptions> <compileCommandOption>-js<compileCommandOption> </compileCommandOptions> <!-- NEW --> <sourceDirectory>${project.basedir}/src/archive</sourceDirectory> <outputDirectory>${project.basedir}/target/classes</outputDirectory> </configuration>
