java.lang.ClassNotFoundException：来自模块 com.amazonaws 的 com.fasterxml.jackson.core.JsonParser$Feature：来自本地模块加载器的 main

Question

我正在开发现有应用程序的增强功能，该应用程序是在 EJB、消息驱动 Bean、Hibernate、Maven 上开发的，作为构建工具，并在 Wildfly 10 上作为服务器。增强功能是从现有应用程序访问 S3 存储桶并将 zip 文件放在那里。因此，我在 pom.xml 文件中添加了 aws 和 opencsv 依赖项。有 MANIFEST.MF 文件，我在其中添加了 amazon aws 和 opencsv 的依赖项，如下所示

Manifest-Version: SR.170.03
Class-Path: 
Dependencies: com.amazonaws,org.hibernate,com.opencsv

我能够使用 Maven clean install 成功构建应用程序。然后我将war文件放在wildfly 10的部署文件夹中。war部署也成功了。当我在调试模式下执行应用程序时，出现以下异常。

java.lang.ClassNotFoundException: com.fasterxml.jackson.core.JsonParser$Feature from Module com.amazonaws:main from local module loader @80169cf (finder: local module finder @5427c60c (roots: D:\Installables\wildfly-10.1.0.Final\modules,D:\Installables\wildfly-10.1.0.Final\modules\system\layers\base))
java.lang.NoClassDefFoundError: com/fasterxml/jackson/core/JsonParser$Feature

我已将 amazonaws jar、fasterxml jar 和 opencsv 放置在 Wildfly 10 模块文件夹中，如下所示

下面是 amazonaws fastxml 和 pom.xml 的 module.xml

我已经浏览了与此类错误相关的主题，但没有得到解决方案。请有人帮忙解决这个问题

我尝试将所有 amazonaws jar 放在 Wildfly 10 模块中的一个位置。

您的 pom.xml 似乎缺少 Jackson 依赖项。

<dependency>
    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-databind</artifactId>
    <version><some_version></version>
</dependency>
