maven中用yuicompressor和closure-compiler对js、css文件进行压缩

项目采用maven构建的时候，需要压缩js，css等，网上找了相关资料，自己综合了下～

直接放代码：

<!-- js压缩 -->
			<plugin>
				<groupId>net.alchim31.maven</groupId>
				<artifactId>yuicompressor-maven-plugin</artifactId>
				<version>1.3.0</version>
				<executions>
					<execution>
						<phase>install</phase>
						<goals>
							<goal>compress</goal>
						</goals>
						<configuration>
							<excludes>
								<exclude>**/*.min.js</exclude>
								<exclude>**/*-min.js</exclude>
							</excludes>
							<nosuffix>true</nosuffix>
							<linebreakpos>-1</linebreakpos>
						</configuration>
					</execution>
				</executions>
			</plugin>
			<!-- native2ascii -->
			<plugin>
				<groupId>org.codehaus.mojo</groupId>
				<artifactId>native2ascii-maven-plugin</artifactId>
				<version>1.0-beta-1</version>
				<executions>
					<execution>
						<phase>install</phase>
						<goals>
							<goal>native2ascii</goal>
						</goals>
						<configuration>
							<workDir>${project.build.directory}/${project.build.finalName}</workDir>
							<excludes>
								<exclude>**/*.css</exclude>
							</excludes>
							<includes>
								<include>resources/js/*.js</include>
							</includes>
						</configuration>
					</execution>
				</executions>
			</plugin>

更喜欢采用谷歌的closure-compiler + maven-antrun-plugin

<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-dependency-plugin</artifactId>
				<version>2.4</version>
				<executions>
					<execution>
						<phase>validate</phase>
						<goals>

									<outputDirectory>${project.build.directory}/compressor</outputDirectory>
									<destFileName>closure-compiler.jar</destFileName>

JQUERY 的压缩工具 uglifyjs版本的配置，必须要有nodejs环境 （executable="node"）即在cmd中能够执行 node --version. uglifyjs可以在https://github.com/mishoo/UglifyJS 下载，下载后续稍稍修改bin/uglifyjs，把里面的

var uglify = require("uglify-js")

修改为

var uglify = require("./uglify-js");//或者 ../uglify-js

因为uglify-js默认是在bin目录外面的。

如需更新uglify的版本，每次覆盖相应文件，只修改上面文件即可。

<echo message="开始压缩 JS 文件. 请耐心等待！" />
								<property name="uglifyjs" value="${project.build.directory}/compressor/uglify/uglifyjs" />
								<property name="yuicompressor" value="${project.build.directory}/compressor/yuicompressor.jar" />
								<property name="closure-compiler" value="${project.build.directory}/compressor/closure-compiler.jar" />
								<property name="css.compress.directory" value="${project.build.directory}/${project.build.finalName}/resources" />
								<property name="js.compress.directory" value="${css.compress.directory}/js" />
								<apply executable="node" parallel="false" failonerror="true" dest="${js.compress.directory}">
									<fileset dir="${js.compress.directory}" includes="**/*.js" />
									<arg line=" ${uglifyjs}" />
									<arg line=" --ascii" />
									<arg line=" -o" />
									<targetfile />
									<srcfile />
									<mapper type="regexp" from="^(.*)\.(js)$" to="\1-min.\2" />
								</apply>
								<move todir="${js.compress.directory}">
									<fileset dir="${js.compress.directory}" includes="**/*.js" />
									<mapper type="regexp" from="^(.*)-min\.(js)$" to="\1.\2" />
								</move>

我用YUI压缩怎么不执行压缩呢，压缩后还是原样？

哦，那个yui压缩应该是可以的啊。你可以试一试nodejs那个，那个是jquery的官方压缩工具。
