踩坑日記-Failure to transfer

報錯緣由

由于導入新的項目，之前依賴的maven-settings.xml檔案被替換，後續替換回settings檔案後，項目maven-clean、maven-install都沒有問題，但是pom.xml檔案會報如下錯誤：

Description Resource    Path    Location    Type
Failure to transfer com.oracle.oracle11g:oracle6:jar:RELEASE2 from http://:/content/groups/public/ was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced. Original error: Could not transfer artifact com.oracle.oracle11g:oracle6:jar:RELEASE2 from/to nexus137 (http://:/content/groups/public/): The operation was cancelled.

出現這個問題的原因是settings檔案的更換，導緻項目找不到對應路徑下的jar封包件，是以報錯。

解決辦法

選中項目，右鍵-maven-maven update即可。
