Я пытаюсь сделать этот урок уже несколько дней.
Я установил Jetty и запускаю с помощью java -jar start.jar.
Но есть проблема, и я не могу запустить http://localhost:8080/webdemo.
На Gradle https://guides.gradle.org/building-java-web-applications/?_ga=2.70016208.115474122.1530432194-1213495054.1529791313
Когда мы выполним эту команду bash gradlew appRun, это будет результат:
$ ./gradlew appRun
:prepareInplaceWebAppFolder
:createInplaceWebAppFolder UP-TO-DATE
:compileJava
:processResources UP-TO-DATE
:classes
:prepareInplaceWebAppClasses
:prepareInplaceWebApp
:appRun
12:25:13 INFO Jetty 9.2.15.v20160210 started and listening on port 8080
12:25:13 INFO webdemo runs at:
12:25:13 INFO http://localhost:8080/webdemo
Press any key to stop the server.

Но это мой результат:
