Exclusion of sass-compiler in confirmdialog means you cannot compile themes

[beirtipol]

Getting this error since adding confirmdialog to my pom:

[ERROR] Error: Could not find or load main class com.vaadin.sass.SassCompiler

Seems to be down to this entry in the pom:

      <dependency>
           <groupId>com.vaadin</groupId>
           <artifactId>vaadin-server</artifactId>
           <version>${vaadin.version}</version>
           <exclusions>
               <exclusion>
                   <groupId>com.vaadin</groupId>
                   <artifactId>vaadin-sass-compiler</artifactId>
               </exclusion>
           </exclusions>
       </dependency>

The workaround is to explicitly add the sass-compiler dependency back in to my pom, but like issue #26 I'm expecting that this plugin shouldn't be explicitly depending on server or excluding the sass compiler
