如何解决Cloud SDK 版本从 3.36.0 升级到 3.42.0 失败
我试图将版本云 sdk jar 从 3.36.0 升级到 3.42.0。构建成功。但是，在应用程序启动期间，我收到以下错误：

看起来像是弹性罐中的“重试”类。请告诉我解决方案。
解决方法
java.lang.ClassNotFoundException: io.github.resilience4j.core.IntervalBiFunction
您的 pom.xml 的依赖项设置似乎存在版本冲突。请运行 mvn dependency:tree 并进行调查。确保 resilience4j-core 只引用了一个版本。使用 <exclusions> 避免使用旧的可传递版本或使用 <dependencyManagement> / <dependency> 强制执行特定版本的 Resilience4j。
请在 SAP Cloud SDK 文档中找到此 guide on dealing with dependency conflicts。
