我有下面提到的我的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，也给出了输出。但是当我在spring xd服务器上部署maven构建过程中生成的jar时，它没有得到jco jar文件的引用。请帮帮忙。如果你需要更多的澄清，请告诉我。

您可以考虑打包依赖项：

或者检查您正在运行已编译jar的类路径，以确保包含sapjco3.jar。
