FAILURE：构建失败并出现异常。

• 出了什么问题： 任务 ':backend:appengineStart' 执行失败。

  在常规位置找不到 Google Cloud SDK，也没有提供路径。

• 尝试： 使用 --stacktrace 选项运行以获取堆栈跟踪。使用 --info 或 --debug 选项运行以获得更多日志输出。运行 --scan 以获得完整的见解。

• 通过https://help.gradle.org获得更多帮助

此版本中使用了已弃用的 Gradle 功能，使其与 Gradle 5.0 不兼容。 使用“--warning-mode all”显示各个弃用警告。 见https://docs.gradle.org/4.10.1/userguide/command_line_interface.html#sec:command_line_warnings

在 5 秒内构建失败 6 个可操作的任务：3 个已执行，3 个最新 下午 6:37:16：任务执行完成“appengineStart”。

Answer 1

在后台构建 gradle

appengine {  // App Engine tasks configuration
    tools.cloudSdkHome="gcloud-sdk-path"
}

gcloud-sdk-path 所在的位置 此处的文档：https://cloud.google.com/appengine/docs/flexible/java/gradle-reference#global_properties
