我使用Maven + Eclipse + M2e + Scala，並注意到eclipse和maven命令行中編譯器的不同行爲。Scala導入編譯器錯誤
例如行家（命令行）抱怨如下：
[ERROR] /home/julien/Documents/donnees/projets/site-garde-enfants/java/service/src/test/scala/com/bignibou/dao/DAOTest.scala:18: error: AdvertisementService is not a member of com.bignibou.service.advertisement
[INFO] import com.bignibou.service.advertisement.AdvertisementService
[INFO] ^
，而我沒有得到日食中的任何編譯器錯誤...
誰能幫助嗎？
