Как исправить ошибку при запуске учебника по огурцам на Mac

Question

Я пытаюсь запустить пример огурец на Mac.Я следовал инструкциям руководства к этой странице (насколько я понял инструкции) и создал файлы, как объяснено на этой странице (то есть файлы annotation.java, runTest.java и outline.feature), как описано в пакетеAnnotation под src/test/java.

Используемые версии:

• MacOS 10.13.6
• затмение: 2019-03 (?) (Невозможно найти версию затмения, действительно раздражает!)
• junit 4.10
• gherkin 2.9.3

Файлы сохранены и не показывают явных ошибок в редакторе eclipse.Но когда я делаю runTest.java -> runAs -> JUnit test, я получаю следующую ошибку:

Feature: annotation

Я не эксперт по java и, конечно, не эксперт по eclipse,Так как мне исправить ошибку?И как я могу связаться с создателями этого учебника, чтобы они могли обновить учебник (сделать его более понятным)?
