SBT 1.2.8 Разрешение зависания ссылок на ключи

#scala #sbt #sbt1.0

#scala #sbt #sbt1.0

Вопрос:

Недавно мы обновили нашу сборку sbt с 0.13.x на 1.2.8 , с тех пор наши агенты сборки часто (не всегда) зависают сразу после

Resolving key references (11281 settings) ...

В дампе потока я вижу следующие строки

- locked <0x00000000800058c0> (a java.lang.ref.Reference$Lock)

- waiting on <0x00000000800058c0> (a java.lang.ref.Reference$Lock)

Это ошибка? если нет, то что я делаю не так? Можете ли вы, пожалуйста, дать совет?

Комментарии:

1. Это слишком много плагинов. Одним из способов устранения неполадок было бы разделить ваш список плагинов пополам: удалите половину из них, посмотрите, исчезнет ли проблема. Если этого не произойдет, удалите половину оставшихся и так далее. Если вы можете воспроизвести проблему вообще без каких-либо плагинов, значит, вы добились значительного прогресса в поиске причины. И / или попробуйте запустить sbt с -debug и посмотрите, выдает ли это какую-либо дополнительную полезную информацию.

2. @SethTisue спасибо за ответ

Ответ №1:

Наш сервер сборки использует другой sbt-launcher ( 0.13.x ), чем тот, который предоставлен в агенте.

В нашем случае проблема устраняется с помощью следующих шагов :

  • Указание версии запуска на sbt-launcher 1.2.8
  • Удален кэш sbt rm -rf ~/.sbt (убедитесь, сделайте резервные копии глобальных .sbt файлов и .credentials файлов и т.д.)
  • Удален кэш ivy rm -rf ~/.ivy2/cache
  • export SBT_OPTS="-Dscala.concurrent.context.maxThreads=1" (из 5 агентов я должен сделать это только в одном агенте)

Я не уверен, исправляет ли это для всех или нет.
