Error:java: Compilation failed: internal java compiler error

JDK版本不一致所导致的，修改下面的四个方面的JDK为相同版本即可。

1、查看项目的jdk 
File ->Project Structure->Project Settings ->Project 

2、查看工程的jdk
File ->Project Structure->Project Settings -> Modules -> Sources -> 

3、查看idea中Java配置 

4.修改pom.xml中的版本为1.8

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
