    As for the "not supported at language level 5", that sounds like an IDE problem to me. Make sure you've configured your project to use Java 7 or later. Commented Jan 27, 2020 at 13:28
  • I fixed the problem by add <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>8</source> <target>8</target> </configuration> </plugin> </plugins> </build> to pom.xml for maven . not sure what's that but It works for me.

  • It means you're targeting Java 8. Your IDE probably read the pom.xml file and auto-configured itself for development in Java 8. Commented Jan 27, 2020 at 13:51
