在初建工程时会自动生成一个pom.xml里面有

<plugin>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.7.0</version>
</plugin>

然后在老师的代码里面加上这个版本，如：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <!-- 下面这一行 -->
  <version>3.7.0</version>
  <configuration>
    <source>1.8</source>
    <target>1.8</target>
    <encoding>UTF-8</encoding>
    <compilerArguments>
      <extdirs>${project.basedir}/src/main/webapp/WEB-INF/lib</extdirs>
    </compilerArguments>
  </configuration>
</plugin>

hi 同学 

看提示i

[ERROR] Re-run Maven using the -X switch to enable full debug logging.

可以增加-X参数看全部的debug的日志。可以试试看具体报错在哪里。

另外可以把教程带的xml文件替换一下，试试是否成功，然后对比一下写法看看哪里有问题呢？

因为我看不到你的xml文件。
