java.lang.NoClassDefFoundError：无法初始化类

标签： java scala sbt bing-api bing-ads-api

我正在尝试从BingAds下载报告。我的代码在IDEA内部下载报告，没什么大问题。当我尝试让它在sbt中运行时：

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

执行失败如：

[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)]

这两个地方都有警告。

我完全迷失了。你有什么可能的解决方案吗？

1 个答案:

答案 0 :(得分：0)

有关密钥库的警告与异常无关。

问题很可能是失败的构建缺乏围绕com.sun.xml.internal.messaging.saaj.soap.SAAJMetaFactoryImpl的依赖关系。 IDEA可能会提供这种依赖性。这是可能的，因为内部构建可能存在于另一个构建环境（类路径/目标平台）中。

NoClassDefFoundErrors的最常见原因是引用类的静态初始化程序（作为根本原因的ExceptionInInitializer）和引用类的ClassNotFoundExceptions引发的异常。后者是如果缺少SAAJMetaFactoryImpl的依赖关系会发生的情况，而不是具有FactoryImpl本身的库。

我怀疑该异常包含另一个Caused-By链接链接，该链接又包含该异常的根本原因，提到实际缺少的类。也许您可以重新配置构建以显示抛出异常的完整原因链。

通常，尝试将两个构建环境与用于解析依赖关系的目标平台进行比较。这使得缺失的库显而易见。
