《Maven实战》学习笔记(4)--常用插件
需要注意一些插件版本，因为有些版本在下载依赖是会出现问题，所以不要使用较新的版本
1.创建源码jar包
启动命令：mvn package，这里人为指定到了verify
<build>
??? <plugins>
??? ??? …………
??? ??? <plugin>
??? ??? ??? <groupId>org.apache.maven.plugins</groupId>
??? ??? ??? <artifactId>maven-source-plugin</artifactId>
??? ??? ??? <version>2.1.2</version>
??? ??? ??? <executions>
??? ??? ??? ??? ??? <execution>
??? ??? ??? ??? ??? ??? <id>attach-sources</id>
??? ??? ??? ??? ??? ??? <phase>verify</phase>
??? ??? ??? ??? ??? ??? <goals>
??? ??? ??? ??? ??? ??? ??? <goal>jar-no-fork</goal>
??? ??? ??? ??? ??? ??? </goals>
??? ??? ??? ??? ??? </execution>
??? ??? ??? </executions>
??? ??? </plugin>
??? ??? …………
??? </plugins>
? </build>
2.扫描webApp下资源文件插件，可以对webApp下的文件使用maven属性进行配置，构建时会自动替换为正确内容
启动命令：mvn package
<build>
??? <plugins>
??? ??? …………
??? ??? <plugin>
??? ??? ??? ??? <groupId>org.apache.maven.plugins</groupId>
??? ??? ??? ??? <artifactId>maven-war-plugin</artifactId>
??? ??? ??? ??? <version>2.1.1</version>
??? ??? ??? ??? <configuration>
??? ??? ??? ??? ??? <webResources>
??? ??? ??? ??? ??? ??? <resource>
??? ??? ??? ??? ??? ??? ??? <filtering>true</filtering>
??? ??? ??? ??? ??? ??? ??? <directory>src/main/webapp</directory>
??? ??? ??? ??? ??? ??? </resource>
??? ??? ??? ??? ??? </webResources>
??? ??? ??? ??? </configuration>
??? ??? ??? </plugin>
??? ??? …………
??? </plugins>
? </build>
3.站点插件,3.0下目前不可用，会报告依赖异常，原因是依赖下缺少某些方法
启动命令：mvn site
<build>
??? <plugins>
??? ??? …………
??? ??? ??? <plugin>
??? ??? ??? ??? <groupId>org.apache.maven.plugins</groupId>
??? ??? ??? ??? <artifactId>maven-site-plugin</artifactId>??? ??? ??? ???
??? ??? ??? ??? <version>2.1.1</version>
??? ??? ??? </plugin>
??? ??? …………
??? </plugins>
? </build>
4.编译插件，因为使用的maven是2.2.1，所以默认使用1.4编译，所以如果使用了junit4的注解，则会出现编译问题，需要指定使用1.5编译
启动命令：mvn compile
<build>
??? <plugins>
??? ??? …………
??? ??? ??? <plugin>
??? ??? ??? ??? <groupId>org.apache.maven.plugins</groupId>
??? ??? ??? ??? <artifactId>maven-compiler-plugin</artifactId>
??? ??? ??? ??? <configuration>
??? ??? ??? ??? ??? <source>1.5</source>
??? ??? ??? ??? ??? <target>1.5</target>
??? ??? ??? ??? </configuration>
??? ??? ??? </plugin>
??? ??? …………
??? </plugins>
? </build>
5.站点插件，以下插件需要声明在<reporting></reporting>中
执行mvn site时都会自动构建
5.1javadoc插件
??? <reporting>???
??? ??? <plugins>
??? ??? ??? …………
??? ??? ??? <!-- javadoc plugin -->
??? ??? ??? <plugin>
??? ??? ??? ??? <groupId>org.apache.maven.plugins</groupId>
??? ??? ??? ??? <artifactId>maven-javadoc-plugin</artifactId>
??? ??? ??? ??? <version>2.7</version>
??? ??? ??? </plugin>
??? ??? ??? …………
??? ??? </plugins>
??? </reporting>
5.2项目源码查看插件
??? <reporting>
??? ??? <plugins>
??? ??? ??? …………
??? ??? ??? <!-- 项目源码 plugin -->
??? ??? ??? <plugin>
??? ??? ??? ??? <groupId>org.apache.maven.plugins</groupId>
??? ??? ??? ??? <artifactId>maven-jxr-plugin</artifactId>
??? ??? ??? ??? <version>2.2</version>
??? ??? ??? ??? <configuration><!-- 只有聚合项目需要使用该配置 -->
??? ??? ??? ??? ??? <aggregate>true</aggregate>
??? ??? ??? ??? </configuration>
??? ??? ??? </plugin>
??? ??? ??? …………
??? ??? </plugins>
??? </reporting>
5.3项目源码分析插件
??? <reporting>
??? ??? <plugins>
??? ??? ??? …………
??? ??? ??? <!-- 项目源码 plugin -->
??? ??? ??? <plugin>
??? ??? ??? ??? <groupId>org.apache.maven.plugins</groupId>
??? ??? ??? ??? <artifactId>maven-pmd-plugin</artifactId>
??? ??? ??? ??? <version>2.5</version>
??? ??? ??? ??? <configuration><!-- 只有聚合项目需要使用该配置 -->
??? ??? ??? ??? ??? <aggregate>true</aggregate>
??? ??? ??? ??? </configuration>
??? ??? ??? </plugin>
??? ??? ??? …………
??? ??? </plugins>
??? </reporting>
构建时可能会提示找不到依赖的jar包，比如我遇到下面的jar找不到
<dependency>
? <groupId>xerces</groupId>
? <artifactId>xercesImpl</artifactId>
? <version>2.6.2</version>
</dependency>
可以从Sonatype Nexus：https://repository.sonatype.org/index.html#welcome上下载，然后上传到nexus上（3rd party）即可
6.部署插件
