Question

我是Gradle的新手，正在阅读这里的Spring Tutorial：

我到达告诉我添加此任务的部分：

task wrapper(type: Wrapper) {
     gradleVersion = '2.3'
}

我运行gradle包装器，它创建了gradlew和gradlew.bat文件。

尝试运行这两个我得到这个例外：

我尝试在https://services.gradle.org/distributions/gradle-2.3-bin.zip点击网络服务器，但我没有收到任何错误。我错过了某种配置？任何帮助，将不胜感激。谢谢！

Answer 1

如果你无论如何都无法修复。如果你在防火墙里面然后，
你可能无法下载https。

应该修复Edit gradle-wrapper.properties文件。

vi [project]/gradle/wrapper/gradle-wrapper.properties

#distributionUrl=https\://services.gradle.org/distributions/gradle-2.8-bin.zip 
distributionUrl=http\://services.gradle.org/distributions/gradle-2.8-bin.zip

从https更改为http ...

Answer 2

我遇到了同样的问题，但是我的症状是我的Ubuntu机器无法解析任何SSL主机，除非我特意将它们添加到Java的证书颁发机构（cacert）文件中。

我偶然发现了这个Debian错误，并找到了一个相当直接的解决方案：删除ca-certificates-java并重新安装：

sudo dpkg --purge --force-depends ca-certificates-java
sudo apt-get install ca-certificates-java

我做了一个./gradlew clean以获得良好的衡量标准，而且一切都重新焕发活力。

Answer 3

看来，gradle网站的证书搞砸了。做一个gradlew clean应该解决这个问题。请参阅Gradle论坛上的此主题：http://discuss.gradle.org/t/urgent-ssl-apache-configuration-for-services-gradle-org-is-bad/8808/4

Answer 4

在我的情况下，问题是由一个过时的（7岁）Java版本引起的。甚至gradlew clean确实失败了。在Java更新之后，它运行良好。

Answer 5

就我而言，我在公司网络中并在代理后面，据我所知，该代理会重写SSL证书，从而使Java安装不信任其中的任何一个。

要解决此问题，我必须在主目录.gradle（~/.gradle/gradle.properties下创建gradle.properties文件，并添加以下行：

org.gradle.jvmargs=-DsystemProp.https.proxyHost=<myProxyHost> -DsystemProp.https.proxyPort=<myProxyPort> -DsystemProp.https.proxyUser=<myProxyUsername> -DsystemProp.https.proxyPassword=<myProxyPassword>

该解决方案基于以下答案：Gradle use certificate authentication for repository

Answer 6

这是因为，Gradle尝试在本地计算机中查找已安装的软件包。如果您已安装位置：

d：\应用\ gradle这个-3.3

在eclipse中执行以下步骤：

新项目
Gradle Project
输入项目名称
本地安装目录
单击“完成”。

你很高兴。

在用户主目录中创建此个人资料：
