Gradle 无法 HEAD https://..pom >对等体未通过身份验证 [英] Gradle Could not HEAD https://..pom > peer not authenticated

问题描述

当您从 gradle 2.0 升级到 2.1 时，您可能会看到以下错误.

When you upgrade from gradle 2.0 to 2.1, you may see following error.

Could not HEAD 'https://jcenter.bintray.com/de/undercouch/gradle-download-task/1.0/gradle-download-task-1.0.pom'.
         > peer not authenticated

公平地说，这个错误不是由于 gradle.是java如何处理ssl连接的问题.

To be fair, this error is not due to gradle. It is problem of how java handles ssl connections.

我正在使用以下 Java 版本.

I am using following java version.

java -version
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b43)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b56, mixed mode)

您可以使用以下答案导入安全证书您的 java 安装.

You can use following answer to import security certificate your java installation.

我不在乎 https 下载，http 对我来说已经足够了.所以看我的回答.

I do not care about https downloads, http is enough for me. So see my answer.

推荐答案

将您的存储库语法更改为以下之一

Change your repository syntax to one of the following

repositories {
    jcenter {
        url "http://jcenter.bintray.com/"
    }
}


repositories {
    maven  {
        url "http://repo1.maven.org/maven2"
    }
}

当前 (2.1) gradle 文档 声称

Warning: Be aware that the central Maven 2 repository is HTTP only 
and HTTPS is not supported. If you need a public HTTPS enabled 
central repository, you can use the JCenter public repository 
(see Section 51.6.3, "Maven JCenter repository").

我认为 maven central 选择了 https.如果我使用以下语法.

I think maven central went for https. If I use following syntax.

repositories {
    mavenCentral()
}

尝试:使用 --stacktrace 选项运行以获取堆栈跟踪.使用 --info 或 --debug 选项运行以获得更多日志输出.
