maven打包的时候默认是不加入依赖的jar包的，所以想打出一个独立的可运行jar包的话直接mvn clean install package是不行的。需要略改动下pom文件，加入如下plugin
<build>
<sourceDirectory>src/main/java</sourceDirectory>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<defaultLibBundleDir>lib</defaultLibBundleDir>
<source>1.5</source>
<target>1.5</target>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix></classpathPrefix>
<mainClass>com.xx.xx.xx</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy</id>
<phase>install</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>
${project.build.directory}
</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-resources-plugin</artifactId>
<version>2.2</version>
<configuration>
<encoding>UTF-8</encoding>
</configuration>
</plugin>
</plugins>
</build>

maven打包的时候有些jar包是不在mavencenter的。需要在pom中引入相关的本地jar包，那么相关的depency应该像如下更改

<dependency>
<groupId>org.wltea.ik-analyzer</groupId>
<artifactId>ik-analyzer</artifactId>
<version>3.2.8</version>
<scope>system</scope>
<systemPath>${project.basedir}/lib/ik-analyzer-3.2.8.jar</systemPath>
</dependency>

对于war包系统来说，有时候需要把jar包打到相关的war包中，可以使用plugin，默认将lib下的所有jar文件打包到WEB-INF/lib下。当然也是可以打包其他的文件的，诸如xml,properties等的。相关的plugin如下：

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
<configuration>
<warName>${project.artifactId}</warName>
<webResources>
<resource>
<directory>lib/</directory>
<targetPath>WEB-INF/lib</targetPath>
<includes>
<include>**/*.jar</include>
</includes>
</resource>
</webResources>
</configuration>
</plugin>
