java.lang.NoSuchMethodError : com. google.api.client.http.HttpTransport.isMtls()Z

标签 java google-app-engine google-cloud-storage google-api-java-client

我有一个使用 java8 部署在 appengine 上的应用程序。
最近，当我尝试部署时，我在运行时收到此错误:

Uncaught exception from servlet
java.lang.NoSuchMethodError: com.google.api.client.http.HttpTransport.isMtls()Z

我会注意到，在过去已经完成部署的电脑上部署时，部署效果很好，但是当第一次在新电脑上部署时，我在运行时遇到上述错误
我假设我需要更改版本
<dependency>
    <groupId>com.google.apis</groupId>
    <artifactId>google-api-services-storage</artifactId>
    <version>RELEASE</version>
</dependency>
应该是什么版本？

最佳答案

通常，当类路径中有同一个类的两个版本时，就会发生这种异常。可能发生的一些原因是:

  • 您的依赖项包括两个版本的 google-api-client。一世
    没有看到任何直接依赖，所以它可能是一个传递
    依赖性。您可以运行 mvn dependency:tree 并寻找google-api-client依赖项和 exclude其中一个 jar
  • 您正在打包提供的
    依赖性。可能是应用引擎已经包含这样的 jar
    使用 HttpTransport，如果您还包括这个 HttpTransport 类
    进入你的人工制品，它会产生问题。要修复此标识
    哪个依赖项包含 HttpTransport 类并在您的 pom.xml 中
    添加提供给它
  • 此类包含在某个生成的存储库中某个旧 jar 的类路径中。如果是这种情况，您所要做的就是重置您的环境。再次克隆存储库并重新初始化应用引擎

    • 关于java.lang.NoSuchMethodError : com. google.api.client.http.HttpTransport.isMtls()Z，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/65826798/
