maven jar war

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

?

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

?

1 2 3 4 5 6 7

<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：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<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>
