谷歌云存储-开始

Question

我正试着遵循GCS入门指南- https://cloud.google.com/appengine/docs/java/googlecloudstorageclient/getstarted

它说我应该下载客户端库，我是用git做的。

然后上面写着：

在“库”选项卡中，单击“添加外部Jars”。您必须添加以下JAR： appengine-gcs-client.jar来自安装库的地方 云存储客户端库安装位置的番石榴-15.0.jar joda-time-2.3.jar来自安装库的地方 appengine安装子目录/lib/ the中的appengine-testing.jar。 appengine安装子目录/lib/impl中的appengine-api.jar。 appengine安装子目录/lib/impl中的appengine-api-stus.jar。

但下载中绝对没有罐子，

我遗漏了什么？?

编辑:我设法在网上找到了丢失的罐子，现在我得到了：

似乎这个指南从来没有被实际测试过，而且完全是浪费时间，还是怎么的？

Answer 1

我遇到了同样的麻烦，对我起作用的是：

1. 将库(appengine + appengine-testing)更新为相同版本的
   • 我以前有appengine版本1.9.18和appenginte-测试版本1.4.0。现在我有了两个版本1.9.25 (目前最新的版本)

​

1. 添加了所有必需的库
   • 缺少api实验室和api存根。

​

我的build.gradle配置现在包含以下内容：

dependencies {
    appengineSdk 'com.google.appengine:appengine-java-sdk:1.9.25'
    compile 'com.google.appengine:appengine-endpoints:1.9.25'
    compile 'com.google.appengine:appengine-endpoints-deps:1.9.25'
    compile 'com.googlecode.objectify:objectify:5.1.5'
    compile 'javax.servlet:servlet-api:2.5'
    testCompile 'junit:junit:4.12'
    testCompile 'com.google.appengine:appengine-testing:1.9.25'
    testCompile 'com.google.appengine:appengine-api-labs:1.9.25'
    testCompile 'com.google.appengine:appengine-api-stubs:1.9.25'

}
