gradlew.bat（和gradlew）SSLHandShakeException [英] gradlew.bat (and gradlew) SSLHandShakeException
本文介绍了gradlew.bat（和gradlew）SSLHandShakeException的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我是新来的Gradle，并且正在浏览这里发现的这个Spring Tutorial：
http://spring.io/guides/gs/gradle/
我得到它告诉我添加此内容的部分任务：
任务包装器（类型：包装器）{
gradleVersion ='2.3'
}
我运行gradle wrapper创建gradlew和gradlew.bat文件。
试图运行这两个我得到这个异常：

我尝试通过 https://services.gradle.org/distributions/访问网络服务器gradle-2.3-bin.zip ，我没有收到任何错误。我我错过了某种配置？任何帮助，将不胜感激。感谢！
解决方案
我遇到同样的问题，但是我的症状是我的Ubuntu机器无法解析任何SSL主机，除非我特别是将它们添加到Java的证书颁发机构（cacert）文件中。
我偶然发现了这个Debian bug，并发现了一个相当直接的解决方法：remove ca-certificates-java 然后重新安装：
sudo dpkg --purge --force-取决于ca-certificates -java
sudo apt-get install ca-certificates-java
I做了一个 ./ gradlew clean 好的衡量标准，所有的事情都重新浮出水面。
I'm new to Gradle and was going through this Spring Tutorial found here:
http://spring.io/guides/gs/gradle/
I get to the part where it tells me to add this task:
task wrapper(type: Wrapper) {
gradleVersion = '2.3'
}
I run gradle wrapper which creates the gradlew and gradlew.bat files.
Trying to run both of this I get this exception:

I try to hit the webserver at https://services.gradle.org/distributions/gradle-2.3-bin.zip and I'm not getting any sort of error. I'm I missing some sort of config? Any help would be appreciated. Thanks!
解决方案
I experienced the same problem, however my symptoms were that my Ubuntu machine couldn't resolve any SSL hosts unless I specifically added them to Java's certificate authority (cacert) file.
I stumbled upon this Debian bug, and found a fairly straight-forward resolution: remove ca-certificates-java and install it again:
sudo dpkg --purge --force-depends ca-certificates-java
sudo apt-get install ca-certificates-java
I did a ./gradlew clean for good measure, and everything sprung to life again.
