IDEA编译Maven任务后target目录没有class

去pom.xml的build标签强行指定需要编译的目录

<resources>
  <resource>
  <directory>src/main/java</directory>
    <includes>
    <include>**/*.xml</include>
    </includes>
  </resource>
  <resource>
  <directory>src/main/resources</directory>
    <includes>
    <include>**/*.*</include>
    </includes>
  </resource>
</resources>
