Gradle + Spring Boot 错误：无法绑定属性

Question

我正在从 Maven 迁移到 Gradle，当通过 Gradle 生成的 jar 文件运行时，Spring 引导服务无法启动。该应用程序作为 Spring 应用程序或作为通过 maven 生成的 jar 运行时运行良好。 我有一种感觉，我们在 Gradle 中缺少一些依赖项，但无法解决。感谢有人能指出我所缺少的。

错误：

Answer 1

发现问题。原来是我的application.properties 文件中已弃用的属性。这需要去：

server.error.include-stacktrace=ON_TRACE_PARAM
