Answer 1

If your project was imported via maven, you can fix the error by adding/editing the maven compiler plugin definition to look like this

    org.apache.maven.plugins
    maven-compiler-plugin
    3.8.0
    
      1.8
      1.8
    

But if you're collaborating on an open source project, then making such a change will need approval first. If it's denied then you can do what 余智平 suggested. But keep in mind that the setting may be reverted if you some how reimport the project as InteliJ will read project configurations again from the POM.
