Answer 1

我想我找到了问题所在。

Apple 已将 rt.jar 更改为位于 classes.jar 中。

/System/Library/Frameworks/JavaVM.framework/Versions/<your_java_version>/类/类.jar

我需要修改我的 pom.xml 以向它显示 classes.jar 的路径。

编辑:在多模块项目中。在 lib 目录中创建指向类 jar 的软链接(soft link)要好得多。

sudo ln -s ../../Classes/classes.jar ./rt.jar

嗯sudo因为写入 /usr/libexec/java_home 的结果command 是您的 java 主目录，需要管理员权限。
