我当时使用的是aws corretto 11 JDK来构建我的项目，但是随后在运行时我遇到了这个异常。
java.lang.UnsupportedClassVersionError： co / paralleluniverse / strands / SuspendableRunnable已由 Java Runtime的最新版本（类文件版本54.0）， 此版本的Java Runtime仅识别类文件版本 高达52.0
经过一番谷歌搜索，我发现当我仅使用intellij运行此代码时，默认情况下使用JDK 8运行我的代码，这就是我无法运行我的项目的原因。
然后，我将intellij更改为使用相同的JDK 11来运行代码，但是在此之后intellij本身还没有启动，请告诉我如何解决此问题。
