在运行glassfish 6.2.0的IDEA中输入java.lang.UnsupportedClassVersionError

Question

我正在使用 IDEA 对 JSF 进行一些分配。我只是用 glassfish 运行一个简单的项目，而 output 是这样的：

输出

Error: A JNI error has occurred, please check your installation and try again
Exception in thread "main" java.lang.UnsupportedClassVersionError: org/glassfish/admin/cli/AsadminMain has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

google了一下，知道version 52就是jdk 8，于是把其他的jdk都删掉，只留下jdk8，确实是1.8的版本：

java 版本

C:\Users\42173>java -version
java version "1.8.0_291"
Java(TM) SE Runtime Environment (build 1.8.0_291-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.291-b10, mixed mode)

C:\Users\42173>javac -version
javac 1.8.0_291

但是还是报同样的错误，不知道怎么办。

而且我试过glassfish5，但是output还是报错：

glassfish5 例外

Answer 1

你得到的错误信息是错误的。

... has been compiled by a more recent version of the Java Runtime (class file version 55.0),
this version of the Java Runtime only recognizes class file versions up to 52.0

它不会告诉您您需要 Java 8 而是 Java 8（类版本52 ）太旧而无法运行由版本55 （即 Java 11）编译的类。

所以你需要安装 JDK 11。
