ScalaDoc生成失败，并显示`java.lang.VerifyError`

Question

我想为我正在处理的项目生成ScalaDocs。我在Mac上使用IntelliJ 2019.1.3。我试图为整个项目和一个打开的文件生成ScalaDocs，但是在所有情况下，输出如下：

Exception in thread "main" java.lang.VerifyError: class scala.tools.nsc.Global overrides final method assert.(ZLscala/Function0;)V

Process finished with exit code 1

想法？
