Answer 1

我对此问题感到有点困惑，因为类路径上没有引用ExternalJob类。事实上，这堂课似乎已经很老了，我找不到最近对它的引用using grepcode ......

在grep访问本地目录后，我在工作目录中找到了一个引用，在一个我没有使用的插件中...

$ grep -r "ExternalJob" *
Binary file work/plugins/external-monitor-job/WEB-INF/lib/classes.jar matches
Binary file work/plugins/external-monitor-job.jpi matches
Binary file work/war/WEB-INF/detached-plugins/external-monitor-job.hpi matches

删除目录（并重新运行./gradlew server）为我解决了这个问题。

也许您应该升级您的＆＃34;外部监视器作业类型插件＆＃34;到最新版本。希望这有帮助。
