(default-compile) on project cloudorde8001: Fatal error compiling

Here is an explanation: everyone’s project environment is different, and the problems encountered are only suitable for some scenarios. You need to refer to this knowledge point flexibly based on the actual situation:
Solution ideas:
1. IDEA compilation method returns to the local user’s settings for the first time. Find the compilation configuration in the xml file

 <profile>
      <id>jdk-1.8</id>

      <activation>
        <property>
          <name>target-env</name>
          <value>dev</value>
        </property>
      </activation>

      <properties>
        <tomcatPath>/path/to/tomcat/instance</tomcatPath>
      </properties>
    </profile>

2. Go back to the idea for the second time to find the compilation level in settings.xml

3. The compiled JDK version is defined in the pom file in maven

 <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.1</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>

4. Set the compilation level of each module in the module
