tomcat

<plugin>
   <groupId>org.apache.tomcat.maven</groupId>
   <artifactId>tomcat7-maven-plugin</artifactId>
   <version>2.1</version>
   <configuration>
      <path>/device-manager-provider</path>
      <uriEncoding>utf-8</uriEncoding>
      <port>8001</port>
      <server>tomcat</server>
      <systemProperties>
         <systemProperty>
            <name>JAVA_OPTS</name>
            <value>-Xms256m -Xmx768m -XX:+UseConcMarkSweepGC
               -XX:MaxPermSize=256m -XX:NewRatio=6
               -XX:+CMSClassUnloadingEnabled -XX:+CMSPermGenSweepingEnabled
            </value>
         </systemProperty>
      </systemProperties>
   </configuration>
</plugin>

dependency

maven-dependency-plugin是处理与依赖相关的插件。它有很多可用的goal，大部分是和依赖构建、分析和解决相关的goal，这部分goal可以直接用maven的命令操作，例如：mvn dependency:tree、mvn dependency:analyze；这类操作在平时的maven应用中很少会用到。这里主要介绍除此之外的、用得最多的几个操作：copy, copy-dependencies和它们对应的unpack, unpack-dependencies

<plugin>
   <artifactId>maven-dependency-plugin</artifactId>
   <executions>
      <execution>
         <id>unpack</id>
         <phase>package</phase>  <!--在打包的的生命周期中，绑定unpack goal-->
         <goals>
            <goal>unpack</goal>  <!--goal 为解压-->
         </goals>
         <configuration>
            <artifactItems>
               <artifactItem>   <!--指定解压的jar包-->
                  <groupId>com.alibaba</groupId>
                  <artifactId>dubbo</artifactId>
                  <version>${project.parent.version}</version>
                   <!--把解压出来的包中的指定文件输出到指定目录，${project.build.directory}默认为target -->
                  <outputDirectory>${project.build.directory}/dubbo</outputDirectory
                   <!--把解压出来的包中的指定文件输出到指定目录--> 
                   <includes>META-INF/assembly/**</includes>

assembly打包

assembly-plugin 打包，把需要打包的jar包，资源都复制到目标文件中，jar包之间不会合并

<plugin>
     <artifactId>maven-assembly-plugin</artifactId>
     <!--assembly.xml配置文件路径-->
     <configuration>
        <descriptor>src/main/assembly/assembly.xml</descriptor>
     </configuration>
     <executions>
       <execution>
       <id>make-assembly</id>
       <phase>package</phase>
       <goals><goal>single</goal></goals>
     </execution>
   </executions>
</plugin>assembly.xml

<assembly>
	<id>assembly</id>
	<formats>
		<format>tar.gz</format>
	</formats>
	<includeBaseDirectory>true</includeBaseDirectory>
	<fileSets>
		<fileSet>
			<!--把target/dubbo/META-INF/assembly/bin  输出到bin 目录-->
			<directory>${project.build.directory}/dubbo/META-INF/assembly/bin</directory>
			<outputDirectory>bin</outputDirectory>
			<fileMode>0755</fileMode>
		</fileSet>
		<fileSet>
			<!--把src/main/assembly/conf 输出到conf 目录-->
			<directory>src/main/assembly/conf</directory>
			<outputDirectory>conf</outputDirectory>
			<fileMode>0644</fileMode>
		</fileSet>
	</fileSets>
		<!--把依赖包输出到lib目录-->
	<dependencySets>
		<dependencySet>
			<outputDirectory>lib</outputDirectory>
		</dependencySet>
	</dependencySets>
</assembly>

发布包到仓库 distributionManagement

pom:

<distributionManagement>
        <repository>
            <id>xxx-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://192.168.41.25:8081/nexus/content/repositories/releases</url>
        </repository>
        <snapshotRepository>
            <id>xxx-snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <url>http://192.168.41.25:8081/nexus/content/repositories/snapshots</url>
        </snapshotRepository>
    </distributionManagement>

maven settings.xml

maven-shade-plugin 打包

shade-plugin把所有依赖的包，文件都整合到一个jar包中

					<!-- 是否生成含有main函数的可执行jar
					 <transformers>  
						 <transformer implementation = "org.apache.maven.plugins.shade.resource.MainifestResourceTransformer">  
						 <mainClass>mainclass</mainClass>  
					 </transformer>  
					-->
					<!--加入资源文件-->
					<transformer implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
