原因：无法找到到请求目标的有效认证路径

时间：2019-10-31 13:43:05

标签： java android android-studio gradle

我收到此错误-

  

错误：原因：无法找到请求的目标的有效证书路径

每当我执行Gradle同步时。 它还表示存在SSL异常，还有resource not found exception for org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.3.41。

但是，我不明白为什么我用Java而不是kotlin编写代码时会遇到关于kotlin的问题。

我正在使用Android Studio 3.5

我到目前为止尝试过的东西：

-将jcenter（）从https更改为http

-试图在公司和家庭网络上运行，但遇到相同的问题

-下载并添加了证书

-卸载并安装的android studio

还请注意，服务器证书中的证书颁发者显示的是我的公司代理而不是CA，无论它是在家中还是公司网络上安装。我在某处读到它，证书颁发者应该是CA。

如果您位于代理之后，则应在gradle.properties文件中包含以下内容。

 systemProp.http.proxyHost=proxy_url
 systemProp.http.proxyPort=proxy_port
 systemProp.http.proxyUser=USER
 systemProp.http.proxyPassword=PWD
 systemProp.https.proxyHost=proxy_url 
 systemProp.https.proxyPort=proxy_port
 systemProp.https.proxyUser=USER
 systemProp.https.proxyPassword=PWD

如果始终遇到相同的问题，则应将jcenter证书添加到JVM的证书中。

Jcenter certificate

如果您的jcenter证书位于其他任何证书中，则应使用此命令将所有证书添加到JVM的cacert中

sudo keytool -import -alias jcenter -keystore  PathToYourCacertFile(in my case :/Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/Contents/Home/jre/lib/security/cacerts) -file path to your cer file (in my case /Users/****/Desktop/jcenter.cer
