google 愿景 api 在 intelliJ 中导入失败

Question

我正在使用 intelliJ IDE 并尝试过 https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/vision/label

我的 pom.xml 没有显示任何错误，如下所示：

但是，java class 无法解决

的依赖关系

我试过了 mvn -U 全新安装

但运气不好

Answer 1

因为您使用的是 Flex 环境。我建议如下

(1) 按照 Java 中的 Flex 快速入门进行操作以确保您的设置正确：https://cloud.google.com/appengine/docs/flexible/java/quickstart

首先在本地测试（使用码头，如快速入门所示）
如果您愿意，之后可以部署到 App Engine Flex

(2) 然后，一旦你知道一切正常（至少在本地使用码头服务器），你就可以向你的 pom.xml 添加以下内容

<dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-vision</artifactId>
    <version>0.9.4-beta</version>
</dependency>

这来自这个页面：https://cloud.google.com/vision/docs/reference/libraries#client-libraries-install-java

您还可以在其中找到代码示例。

(3) 顺便说一句：对于 Auth，我建议在您的机器上本地设置一个服务帐户。为此，您需要在 Cloud Console 中创建一个服务帐户，然后在本地下载一个 .json 文件，然后设置环境变量 GOOGLE_APPLICATION_CREDENTIALS 以指向该 .json 文件.
