How to resolve repository certificate error in Gradle build
提问by Ajay Kulkarni
I installed latest version of android studio. I had jdk 8 which was already installed. When I opened android studio, I got below error.
我安装了最新版本的android studio。我已经安装了 jdk 8。当我打开android studio时，出现以下错误。
Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve com.android.support:appcompat-v7:26.1.0.
Could not resolve com.android.support:appcompat-v7:26.1.0.

So I removed JDK 8 and installed JDK 9, added environment variables (in windows 10). Then I restarted my system and started android studio, I still got above error. I even added
所以我删除了 JDK 8 并安装了 JDK 9，添加了环境变量（在 Windows 10 中）。然后我重新启动了我的系统并启动了 android studio，我仍然遇到上述错误。我什至补充说
repositories {
maven { url "https://maven.google.com" }
}
to gradle script. But I'm still getting same error. How do I fix this error?
gradle 脚本。但我仍然遇到同样的错误。我该如何解决这个错误？

Modify in project level gradle according below
根据以下在项目级别的gradle中修改
// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.0.0'
// NOTE: Do not place your application dependencies here; they belong
// in the individual module build.gradle files
}
}
allprojects {
repositories {
google()
jcenter()
}
}
task clean(type: Delete) {
delete rootProject.buildDir
}
Then, remove appcompat-v7:26.1.0 dependency from app level gradle then next Go to Android Studio File > Project Structure > app >Dependencies > tap on + > Library Dependencies > add dependenceis as per your requirements then OK.
然后，从应用程序级别的 gradle 中删除 appcompat-v7:26.1.0 依赖项，然后转到 Android Studio File > Project Structure > app >Dependencies > 点击 + > Library Dependencies > 根据您的要求添加依赖项然后 OK。
Also you can try to tap on synchronize project with gradle file
您也可以尝试点击将项目与 gradle 文件同步

Your Java is not trusting the link you are using to download library. Before proceeding on to step 2, Try step 1.
您的 Java 不信任您用来下载库的链接。在继续执行第 2 步之前，请尝试执行第 1 步。
Check if your internet is behind any firewall, Your company internet could be blocking the website you are trying to access. connect your PC to your mobile internet and trying building.
Add certificate manually to your jdk cert strore.
- Visit the website for example https://example.com
- download the certificate from browser.
- Find your jdk installation directory.
- add cert manually to cacerts using below command,
sudo keytool -import -alias shibbolethnet -keystore
/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home/jre/lib/security/cacerts -file <downloadedcert.cer>
检查您的互联网是否在任何防火墙之后，您公司的互联网可能会阻止您尝试访问的网站。将您的 PC 连接到您的移动互联网并尝试构建。
手动将证书添加到您的 jdk 证书存储中。
- 访问网站，例如https://example.com
- 从浏览器下载证书。
- 找到你的jdk安装目录。
- 使用以下命令手动将证书添加到 cacerts，
sudo keytool -import -alias shibbolethnet -keystore
/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home/jre/lib/security/cacerts -file <downloadedcert.cer>

You can try changing the path for the Gradle wrapper going to Eclipse > Preferences > Gradle. Choose Local Installation directory instead of Gradle Wrapper.
您可以尝试将 Gradle 包装器的路径更改为 Eclipse > Preferences > Gradle。选择本地安装目录而不是 Gradle Wrapper。
