Любая помощь в преодолении этой ошибки будет принята с благодарностью. Поиск в Google не дает никаких полезных результатов. Я использую Macbook Pro под управлением OSX Yosemite и использую Java 1.7.0_71 с Maven 3.3. Maven был установлен через HomeBrew.
Чтобы познакомиться с Google App Engine, я следовал инструкциям по быстрому запуску из https://cloud.google.com/appengine/docs/java/gettingstarted/introduction и перейдите к инструкциям на странице по адресу https://cloud.google.com/appengine/docs/java/gettingstarted/.ui_and_code без проблем. После создания файла guestbook.jsp и запуска mvn appengine:devserver
я получаю следующую ошибку сборки.
