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：

Xml代码

<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>

            

            <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

Xml代码

                        <phase>validate</phase>

                        <goals>

                            <goal>copy</goal>

                        </goals>

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

Js代码

var uglify = require("uglify-js")

修改为

Js代码

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。
