类路径冲突问题(com.google.api.client.http.HttpTransport)

Question

我正在努力让我的 spring 引导应用程序启动，它在引导时出现此错误：

***************************
APPLICATION FAILED TO START
***************************
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
    com.google.api.services.sqladmin.SQLAdmin$Builder.chooseEndpoint(SQLAdmin.java:7296)
The following method did not exist:
    'boolean com.google.api.client.http.HttpTransport.isMtls()'
The method's class, com.google.api.client.http.HttpTransport, is available from the following locations:
    jar:file:/Users/benz/.m2/repository/com/google/http-client/google-http-client/1.35.0/google-http-client-1.35.0.jar!/com/google/api/client/http/HttpTransport.class
The class hierarchy was loaded from the following locations:
    com.google.api.client.http.HttpTransport: file:/Users/benz/.m2/repository/com/google/http-client/google-http-client/1.35.0/google-http-client-1.35.0.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of com.google.api.client.http.HttpTransport

让我指定此应用程序有两种配置：

一个用于本地开发，它连接到本地 postgresql
一个用于运行在 Google 云（AppEngine）上并使用 Google 云 SQL

大更新后，由于这个问题，云配置文件不再工作。

据我了解，这可能是一个依赖问题，必须通过 maven 解决。

[INFO] +- com.google.firebase:firebase-admin:jar:6.16.0:compile
[INFO] |  +- com.google.api-client:google-api-client:jar:1.30.10:compile
[INFO] |  |  +- com.google.oauth-client:google-oauth-client:jar:1.31.0:compile

[INFO] |  +- com.google.http-client:google-http-client:jar:1.35.0:compile

据我所知，这是唯一重复的 http 客户端。我试图降级 firebase-admin 库，但它的依赖项保持在相同的版本号。

可能我做错了什么。有人知道如何解决这个问题吗？我已经浪费了很多时间......没有运气......

谢谢

此方法包含在 google-http-java-client 以及对 add support for mtls. This is the relevant commit 的其他更改中。

此代码已在库的 1.38.0 版本上发布。

该库版本 seems to be compatible 与您的 firebase-admin 版本。

请尝试将以下内容作为第一级 Maven 依赖项包括在内：

<dependency>
    <groupId>com.google.http-client</groupId>
    <artifactId>google-http-client</artifactId>
    <version>1.38.0</version>
</dependency>

也许您也可以使用 google-http-client 的 more recent version。
