我试图创建一个基于wso2cep 4.0.0文档的自定义输入事件接收器和来自cep / repository / components / plugins的文件尾输入事件接收器的反编译版本。（https://docs.wso2.com/display/CEP400/Building+Custom+Event+Receivers）。< / p>
到目前为止，我已设法添加反编译版本中的所有类，并基于此构建项目。在我将其复制到cep_home / repository / components / dropins中之后，我尝试启动CEP服务器，然后我遇到了这个：

我不明白为什么在原始编译的适配器中该类是相同的并且它有效并且在我的情况下它不会。
任何人都可以帮助我？非常感谢你！
（如果您需要有关此问题的任何其他信息，请在评论中告诉我，谢谢）
答案 0 :(得分：1)
经过一些研究并感谢Dilini（谢谢！）我设法发现错误出现是因为我错误地配置了Resources文件夹，它是
src/main/resources/org/wso2/event/adapter/multiplefiletail/i18n/Resources
而不是
src/main/resources/org/wso2/carbon/event/input/adapter/multiplefiletail/i18n/Resources
就像它在MultipleFileTailEventAdapterFactory类中配置一样，出现错误。希望它有所帮助！
