gradlew.bat(和gradlew)SSLHandShakeException

Question

我是Gradle的新手,正在阅读这里的Spring Tutorial:

http://spring.io/guides/gs/gradle/

我到达它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.

试图运行这两个我得到这个例外:

我尝试访问https://services.gradle.org/distributions/gradle-2.3-bin.zip上的网络服务器,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.如果你在防火墙内
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 ...

我遇到了同样的问题,但我的症状是我的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.

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并重新安装它:

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

我做了一个./gradlew clean很好的措施,一切都恢复了生机.
