我正在遵循 Google 官方示例
https://developers.google.com/analytics/devguides/reporting/data/v1/quickstart-client-libraries
在带有 Maven 的 Netbeans 中。
本例中的代码片段
try (BetaAnalyticsDataClient analyticsData = BetaAnalyticsDataClient.create()) {
RunReportRequest request
= RunReportRequest.newBuilder()
.setProperty("properties/" + propertyId)
.addDimensions(Dimension.newBuilder().setName("city"))
.addMetrics(Metric.newBuilder().setName("activeUsers"))
.addDateRanges(DateRange.newBuilder().setStartDate("2023-07-31").setEndDate("today"))
.build();
}
立即失败

有人知道为什么吗？这是我能找到的用 Java 连接 GA4 的最简单的示例，但它一开始就失败了。
我确实注意到该示例没有指示任何类型的身份验证？
我已经搜索到课程了
com.google.auth.oauth2.GdchCredentials
但在任何地方都找不到它的参考 - 那么为什么官方 Google GA4 Java API 库需要它 - 它不存在 - 任何地方？
我的导入等与上面 URL 的示例完全相同...

我的用例中显示的此特定问题/异常的解决方案是将 google-auth-library-oauth-2-http 依赖项的 Maven 工件升级到截至 2023 年 8 月 08 日的当前版本：
<dependency>
<groupId>com.google.auth</groupId>
<artifactId>google-auth-library-oauth2-http</artifactId>
<version>1.19.0</version>
<type>jar</type>
</dependency>
在 NetBeans Maven 项目的 pom.xml 中。
