写了一个spring-mvc的项目，用netty启动。所以要打成一个可执行的jar包
pom.xml如下
<build>

    <finalName>platform_netty</finalName>     <plugins>         <!--指定maven编译版本-->         <plugin>             <groupId>org.apache.maven.plugins</groupId>             <artifactId>maven-compiler-plugin</artifactId>             <version>2.3.2</version>             <configuration>                 <source>1.8</source>                 <target>1.8</target>             </configuration>         </plugin>         <plugin>             <groupId>org.apache.maven.plugins</groupId>             <artifactId>maven-jar-plugin</artifactId>             <version>2.6</version>             <configuration>                 <archive>                     <manifest>                         <addClasspath>true</addClasspath>                         <classpathPrefix>lib/</classpathPrefix>                         <mainClass>com.xx.action.NettyServer</mainClass>                     </manifest>                 </archive>             </configuration>         </plugin>         <plugin>             <groupId>org.apache.maven.plugins</groupId>             <artifactId>maven-dependency-plugin</artifactId>             <version>2.10</version>             <executions>                 <execution>                     <id>copy-dependencies</id>                     <phase>package</phase>                     <goals>                         <goal>copy-dependencies</goal>                     </goals>                     <configuration>                         <outputDirectory>${project.build.directory}/lib</outputDirectory>                     </configuration>                 </execution>             </executions>         </plugin>      </plugins> </build> 

然后使用mvn package打包一直报

环境配置如下：
java_home:

path:

jdk目录下有tools.jar:

cmd的jdk检查

所以想问，为啥maven无法package
