java.lang.NoClassDefFoundError：無法初始化類

Question

我正在嘗試從BingAds下載報告。 我的代碼在IDEA內部下載報告，沒什么大問題。 當我試圖讓它在sbt里面運行時：

H24_BING_CONFIG = / home / oleber / del / develop_bing.json sbt clean'project importerBing''run'

執行失敗如：

[oleber] [WARN] [home24-aws] [org.apache.cxf.transport.https.HttpsURLConnectionFactory] [Default key managers cannot be initialized: /home/oleber/.keystore (No such file or directory)]
[oleber] [WARN] [home24-aws] [org.apache.cxf.transport.https.HttpsURLConnectionFactory] [Default key managers cannot be initialized: /home/oleber/.keystore (No such file or directory)]

警告在兩個地方都有。

我完全迷失了。 你有什么可能的解決方案嗎？

Answer 1

有關密鑰庫的警告與異常無關。

問題很可能是失敗的構建缺少與com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl相關的依賴關系。 IDEA可能會提供這種依賴性。 這是可能的，因為內部構建可能存在於另一個構建環境（類路徑/目標平台）中。

NoClassDefFoundErrors的最常見原因是在引用類的靜態初始化程序（作為根本原因的ExceptionInInitializer）和引用類的ClassNotFoundExceptions引發的異常。 后者是如果缺少SAAJMetaFactoryImpl的依賴關系會發生的情況，而不是具有FactoryImpl本身的庫。

我懷疑該異常包含另一個Caused-By鏈接鏈接，該鏈接又包含該異常的根本原因，提到實際缺少的類。 也許您可以重新配置構建以顯示拋出異常的完整原因鏈。

通常，嘗試將兩個構建環境與它們用於解析依賴關系的目標平台進行比較。 這使得缺失的庫變得明顯。
