Почему NoClassDefFoundError выбрасывается с помощью "run", но отлично работает с "dist"?

Question

Почему NoClassDefFoundError выбрасывается с помощью "run", но отлично работает с "dist"?

Прежде чем задавать вопрос, я прочитал вопрос Play framework java.lang.NoClassDefFoundError только в режиме разработки и нескольких других постах. Они не помогли мне решить мою проблему.

Я создал проект с использованием Typesafe Activator 1.2.12 и play-scala шаблон. Я также использовал Slick 2.1.0.

Я хочу встроить базу данных h2 с расширением h2gis в игру.

Когда проект Play запущен с использованием activator run, следующие Execution exception отображается в браузере:

Следующая трассировка стека находится на консоли:

Тем не менее, если я выполню activator distи запустить приложение, оно работает хорошо (!)

JAR-файл для h2 находится в lib и в ссылке на sbt, и без использования h2gis, ошибки не возникает.

Исходный код проекта находится на GitHub как проект с странными ошибками. Используйте проект, чтобы столкнуться с ошибкой.

Обновить:

Вот вывод трассировки с командой ./activator run -J-XX:+TraceClassLoadingКажется, я вставляю только часть этого CoordinateArraySequence поднять исключение.

Попробуйте добавить эти зависимости в файл build.sbt вместо того, чтобы помещать jar-файлы в lib.

"com.typesafe.slick" %% "slick" % "2.1.0",
"org.orbisgis" % "h2gis" % "1.1.0",
"com.vividsolutions" % "jts" % "1.13"

в режиме dev, play sbt будет использовать несколько загрузчиков классов для поддержки горячей перезагрузки, тогда как после dist будет только один загрузчик классов для обработки вашего проекта. С учетом вышесказанного, размещение вещей в одном месте может решить вашу проблему.
