vaadin-style-combine-maven-plugin

Maven plugin for combining multiple css files into a single styles.css

This maven plugin will combine style.css files so that only one request will be made. It works in a limited amount of scenarios, similar to the way Vaadin does it. It requires a theme to have a "styles.css" like this:

			@import "../reindeer/styles.css";
			@import "general/general.css";
			@import "header/header.css";

After it has run, it will generate a folder "generated-vaadin-styles" in "target".

To use this one instead of the original, use the following maven-war-plugin config:

			<groupId>org.apache.maven.plugins</groupId>
			<artifactId>maven-war-plugin</artifactId>
			<configuration>
				<excludes>VAADIN/themes/theme/styles.css</excludes>
				<packagingExcludes>WEB-INF/web.xml</packagingExcludes>
				<webResources>
        			<resource>
        				<directory>${project.build.directory}/generated-vaadin-styles/</directory>
        			</resource>
        		</webResources>
			</configuration>

To run the combine plugin:

		<plugin>
			<groupId>de.codecentric.vaadin</groupId>
			<artifactId>vaadin-style-combine-maven-plugin</artifactId>
			<version>1.0</version>
			<configuration>
				<theme>theme</theme>
			</configuration>
			<executions>
				<execution>
					<phase>compile</phase>
					<goals>
						<goal>combine</goal>
					</goals>
				</execution>
			</executions>
		</plugin>
