我有如下所述的 POM.xml -

<dependency>
  <groupId>com.sap.conn.jco</groupId>
  <artifactId>sapjco3</artifactId>
  <version>3.0.15</version>
  <scope>system</scope>
  <systemPath>${pom.basedir}\src\main\resources\sapjco3.jar</systemPath>
</dependency>

我还添加了指向 jco3.jar 文件的 Class-Path 环境变量和指向 jco 库文件夹的 Path 变量。当直接在 eclipse 中运行代码时，它正在工作，也给出输出。但是当我在 spring xd 服务器上部署在 maven 构建期间生成的 jar 时，它没有获取 jco jar 文件的引用。请帮忙。如果您需要更多说明，请告诉我。

您可以考虑打包依赖项:

How can I create an executable JAR with dependencies using Maven?

或者检查运行已编译 jar 的类路径，以确保包含 sapjco3.jar。
