我正在尝试使用 Spring Boot 配置 Google Cloud Datastore API，以便将其部署在 Compute Engine 上。当我尝试在本地运行 Spring Boot 项目时，我不断收到以下错误
org.apache.catalina.core.ContainerBase : A child container failed during start
问题 我使用 Spring Initizr ( http://start.spring.io/ ) 构建了一个演示项目，并为 Google Cloud Datastore API 添加了 maven 依赖项，如下所示
<dependency>
<groupId>com.google.cloud</groupId>
<artifactId>gcloud-java-datastore</artifactId>
<version>0.2.0</version>
</dependency>
我能够构建项目，但是当我运行项目时，它无法启动嵌入式 Tomcat。一旦我删除了 Google Cloud Datastore 依赖项，Spring Boot 就可以正常工作。
