但是在我使用这个命令之后 JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee ，这就是我得到的错误:无法找到或加载主类 '-XX:+IgnoreUnrecognizedVMOptions 原因:java.lang.ClassNotFoundException: '-XX:+IgnoreUnrecognizedVMOptions
but after I use this command JAVA_OPTS=-XX:+IgnoreUnrecognizedVMOptions --add-modules java.se.ee ,this what I get
Error: Could not find or load main class '-XX:+IgnoreUnrecognizedVMOptions Caused by: java.lang.ClassNotFoundException: '-XX:+IgnoreUnrecognizedVMOptions
