eclipse中maven打包

第一种方式：将依赖包打包进一个jar包中。

  <build>
      <plugins>
          <plugin>
              <artifactId>maven-compiler-plugin</artifactId>
              <configuration>
                  <source>1.8</source>
                  <target>1.8</target>
                  <encoding>${project.build.sourceEncoding}</encoding>   
              </configuration>
          </plugin>
          <plugin>  
            <artifactId>maven-assembly-plugin</artifactId>  
            <configuration>  
              <descriptorRefs>  
                <descriptorRef>jar-with-dependencies</descriptorRef>  
              </descriptorRefs>  
              <archive>    
                <manifest>    
                    <mainClass></mainClass>  
                </manifest>  
            </archive>  
        </configuration>  
        <executions>  
          <execution>  
            <id>make-assembly</id> <!-- this is used for inheritance merges -->  
            <phase>package</phase> <!-- bind to the packaging phase -->  
            <goals>  
              <goal>single</goal>  
            </goals>  
          </execution>  
        </executions>  
       </plugin>  
      </plugins>
  </build>

第二种方式： 将依赖包单独放到lib文件夹中

<build>
    <finalName><!--可以自定义jar包名--></finalName>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>2.3.2</version>
            <configuration>
                <source>1.8</source>
                <target>1.8</target>
                <encoding>UTF-8</encoding>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
            <executions>
                <execution>
                    <id>copy-dependencies</id>
                    <phase>prepare-package</phase>
                    <goals>
                        <goal>copy-dependencies</goal>
                    </goals>
                    <configuration>
                        <outputDirectory>${project.build.directory}/lib</outputDirectory>
                        <overWriteReleases>false</overWriteReleases>
                        <overWriteSnapshots>false</overWriteSnapshots>
                        <overWriteIfNewer>true</overWriteIfNewer>
                    </configuration>
                </execution>
            </executions>
        </plugin>
        <plugin>  
            <groupId>org.apache.maven.plugins</groupId>  
            <artifactId>maven-jar-plugin</artifactId>  
            <version>2.4</version>  
            <configuration>  
                <archive>  
                <!--不打包依赖的jar,把依赖的jar copy到lib目录，和生成的jar放在同一级目录下   -->
                    <manifest>  
                        <addClasspath>true</addClasspath>  
                        <classpathPrefix>lib/</classpathPrefix>  
                        <mainClass></mainClass>  
                    </manifest>  
                </archive>  
            </configuration>  
        </plugin>  
    </plugins>
</build>
