我试图从 Postman 客户端调用一个 mule API，但我收到了 500 错误。我不确定我明白发生了什么。我已经在下面发布了错误。我不确定这是否是 Maven 依赖性问题。任何帮助，将不胜感激............................................. ..................................................... ............

Answer 1

Jenkins 实例返回错误。 Mule 在该错误中没有生成任何内容。您要么调用了错误的服务器，要么 Mule 应用程序只是 Jenkins 的代理。无论哪种方式，错误都在 Jenkins 中，您需要调查 Jenkins 在做什么。
