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

转载自：http://matychen.iteye.com/blog/1477350

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：

1. <!-- js压缩 -->
2. <plugin>
3. <groupId>net.alchim31.maven</groupId>
4. <artifactId>yuicompressor-maven-plugin</artifactId>
5. <version>1.3.0</version>
6. <executions>
7. <execution>
8. <phase>install</phase>
9. <goals>
10. <goal>compress</goal>
11. </goals>
12. <configuration>
13. <excludes>
14. <exclude>**/*.min.js</exclude>
15. <exclude>**/*-min.js</exclude>
16. </excludes>
17. <nosuffix>true</nosuffix>
18. <linebreakpos>-1</linebreakpos>
19. </configuration>
20. </execution>
21. </executions>
22. </plugin>
23. <!-- native2ascii -->
24. <plugin>
25. <groupId>org.codehaus.mojo</groupId>
26. <artifactId>native2ascii-maven-plugin</artifactId>
27. <version>1.0-beta-1</version>
28. <executions>
29. <execution>
30. <phase>install</phase>
31. <goals>
32. <goal>native2ascii</goal>
33. </goals>
34. <configuration>
35. <workDir>${project.build.directory}/${project.build.finalName}</workDir>
36. <excludes>
37. <exclude>**/*.css</exclude>
38. </excludes>
39. <includes>
40. <include>resources/js/*.js</include>
41. </includes>
42. </configuration>
43. </execution>
44. </executions>
45. </plugin>

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

1. <plugin>
2. <groupId>org.apache.maven.plugins</groupId>
3. <artifactId>maven-dependency-plugin</artifactId>
4. <version>2.4</version>
5. <executions>
6. <execution>
7. <phase>validate</phase>
8. <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

1. var uglify = require("uglify-js")

修改为

1. 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。

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