本文介绍了Maven中常用的插件配置，包括Tomcat插件、Scala插件、源码包含插件、编译插件、测试插件、依赖打包插件、CSS/JS压缩插件等。详细展示了如何配置这些插件以实现项目部署、Scala项目编译、源码包含、JDK版本指定、测试用例执行、依赖打包、静态资源压缩等功能。

1. tomcat7-maven-plugin

配置pom.xml

<!-- scope设置为provided -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
    <scope>provided</scope>
</dependency>

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
</dependency>


<!-- 配置tomcat插件 -->
<plugin>
     <groupId>org.apache.tomcat.maven</groupId>
     <artifactId>tomcat7-maven-plugin</artifactId>
     <version>2.2</version>
     <configuration>
          <port>8080</port>
       
          <!-- 项目的根路径  http://localhost:8080/test -->
          <path>/test</path>
      </configuration>
 </plugin>

启动 maven build: tomcat7:run 或是idea

2. scala-maven-plugin

# 作用是让maven能够编译、测试、运行scala项目
<plugin>
    <!-- see http://davidb.github.com/scala-maven-plugin -->
    <groupId>net.alchim31.maven</groupId>
    <artifactId>scala-maven-plugin</artifactId>
    <version>3.2.0</version>
    <executions>
        <execution>
            <goals>
                <goal>compile</goal>
                <goal>testCompile</goal>
            </goals>
            <configuration>
                <args>
                    <!--<arg>-make:transitive</arg> -->
                    <arg>-dependencyfile</arg>
                    <arg>${project.build.directory}/.scala_dependencies</arg>
                </args>
            </configuration>
        </execution>
    </executions>
</plugin>

3. maven-source-plugin

#  包含源码
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-source-plugin</artifactId>
    <version>3.0.1</version>
    <configuration>
        <attach>true</attach>
    </configuration>
    <executions>
        <execution>
            <phase>compile</phase>
            <goals>
                <goal>jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

4. maven-compiler-plugin

# 指定编译的JDK
 <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
           <source>1.8</source>
           <target>1.8</target>
      </configuration>
 </plugin>

5. maven-surefire-plugin

<!--
   maven里执行测试用例的插件，不显示配置就会用默认配置。
   这个插件的surefire:test命令会默认绑定maven执行的test阶段。
-->
<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-surefire-plugin</artifactId>
   <version>2.18.1</version>

       <!-- useManifestOnlyJar>false</useManifestOnlyJar -->
       <includes>
           <include>**/*Test.*</include>
           <include>**/*Suite.*</include>
       </includes>
    </configuration>
</plugin>

6. maven-shade-plugins

<!--
   两大基本功能：

   - 将依赖的jar包打包到当前jar包（常规打包是不会将所依赖jar包打进来的）；
   - 对依赖的jar包进行重命名（用于类的隔离）；
-->
<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-shade-plugin</artifactId>

     </configuration>
     <executions>
         <execution>

                            <exclude>META-INF/*.RSA</exclude>
                         </excludes>
                     </filter>
                 </filters>
             </configuration>
          </execution>
      </executions>
</plugin>

7. css/js压缩

 <!-- YUI Compress (CSS/JS压缩) -->
 <plugin>
     <groupId>net.alchim31.maven</groupId>

          <jswarn>false</jswarn>
          <nosuffix>true</nosuffix>
          <linebreakpos>30000</linebreakpos>
          <force>true</force>
          <includes>
              <include>**/*.js</include>

              <exclude>**/*.min.css</exclude>
          </excludes>
      </configuration>
 </plugin>

8. 打包时，加入lib包下的jar。

 <!-- 打包jar文件时时，配置manifest文件，加入lib包的jar依赖 -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <configuration>
                    <archive>
                        <addMavenDescriptor>false</addMavenDescriptor>
                    </archive>
                </configuration>
                <executions>
