【问题描述】：
您好，我在 openshift 环境中运行 Spring Cloud Data Flow Server (v2.6.2-SNAPSHOT)。每次我从 SCDF 安排或启动任务时说 Failed to retrieve properties for resource，我都会收到 NullPointerException。我正在将我的 Springboot 批处理应用程序注册为 SCDF 中的 Docker 映像。下面是异常跟踪。
虽然它无论如何都不会影响任务执行，但它会在 SCDF 容器中生成大量日志。我们通常每 10 分钟运行一次批次。
我搜索了这个问题并找到了指向 github 的链接，上面说它已在旧版本中修复。但不确定它在 V2.6.2 中是如何发生的。我希望这就是票的问题。
Github 票：ApplicationConfigurationMetadataResolver
如果有什么办法可以解决这个问题，请告诉我。
