maven打包加入依赖包以及加入本地依赖包的方法

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

<?xml version="1.0" encoding="utf-8"?>

<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/>  
            <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

<?xml version="1.0" encoding="utf-8"?>

<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>
