Невозможно создать пример приложения "Книжная полка для Java в стандартной среде App Engine" из Google, проблема с pom.xml?

Question

Я пытаюсь получить книжное приложение для Java на движке APP «https://cloud.google.com/java/getting-started-appengine-standard/tutorial-app"

Я выполнил все шаги, такие как настройка биллинга для моего проекта, включение API и загрузка SDK.

Я клонировал репо, т. Е.

мерзавец клон https://github.com/GoogleCloudPlatform/getting-started-java.git

Тогда я продолжаю бежать

mvn -Plocal clean appengine:devserver

из каталога

getting-started-java/bookshelf-standard/2-structured-data

Здесь вещи становятся странными. В pom.xml, когда я устанавливаю плагин appengine maven и версию appengine-api-1.0-sdk на 1.9.73, которая является последней версией

Я получаю ошибку

Ошибка при открытии zip-файла или JAR-манифеста: /home/anirudh/.m2/repository/com/google/appengine/appengine-java-sdk/1.9.73/appengine-java-sdk/appengine-java-sdk-1.9.73/lib/agent/appengine-agent. баночка

Теперь я попытался использовать более старую версию плагина maven и appengine-api-1.0-sdk, а именно

Я не могу создать DevAppserver

Судя по трассировке стека, вы пытаетесь запустить Java 9+. Попробуйте запустить с Java 8.
