Android Studio 3.0 中的 Gradle 构建错误

2024-05-25

您能帮我解决 Android 3.0 中的 Gradle 构建问题吗？

我是 Android Studio 的新手。以下是我在 AS 3.0 中的配置：

gradle->wrapper->gradle-wrapper.properties：

distributionUrl=https\://services.gradle.org/distributions/gradle-4.2.1-all.zip

build.gradle 依赖项（Gradle 的 Android 插件）：

dependencies {classpath 'com.android.tools.build:gradle:3.0.0'}

Android Studio 的堆栈跟踪：

D:\AppiumAutomation\MobileTest>gradlew assemble --stacktrace

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'MobileTest'.
> Could not resolve all files for configuration ':classpath'.
   > Could not resolve com.android.tools.build:gradle:3.0.0.
     Required by:
         project :

这是与 Android Studio 3.0 和企业网络相关的问题。我有同样的问题。

我给你留下2个解决方案：

第一：您必须手动将证书添加到您的 java 安全证书（由 Android 使用）：

C:\Program Files\Android\Android Studio\jre\jre\lib\security\cacerts

解决方案01（对我不起作用）：

Go to:

C:\Program Files\Android\Android Studio\jre\jre\bin

下载您需要的证书（只需复制有问题的 URL 并将其粘贴到<remote_host_name>):

keytool -J-Dhttps.proxyHost=<proxy_hostname> -J-Dhttps.proxyPort=<proxy_port> -printcert -rfc -sslserver <remote_host_name:remote_ssl_port> > <name.cer>

Example:
C:\Program Files\Android\Android Studio\jre\jre\bin>keytool -J-Dhttps.proxyHost= proxy.mycompany.com -J-Dhttps.proxyPort=80 -printcert -rfc -sslserver https://dl.google.com/dl/android/maven2/com/android/support/test/runner/1.0.1/runner-1.0.1.pom > maven2.cer

并运行命令：

keytool -import -noprompt -trustcacerts -keystore ..\lib\security\cacerts -importcert -alias <AliasName> -file <name.cer> -storepass <cacertsPassword>

如果您从未更改过 cacerts 的密码，则默认密码是changeit:

Example:
C:\Program Files\Android\Android Studio\jre\jre\bin>keytool -import -noprompt -trustcacerts -keystore ..\lib\security\cacerts -importcert -alias Maven -file maven2.cer -storepass changeit

解决方案02（为我工作）：

下载输入 URL 站点的 pom 并将其存储在本地存储库中：

Ex:
If your missing resoruce is:
https://dl.google.com/dl/android/maven2/com/android/support/test/espresso/espresso-core/3.0.1/espresso-core-3.0.1.pom

Download it and put it in:
C:/Program Files/Android/Android Studio/gradle/m2repository/com/android/support/test/espresso/espresso-core/3.0.1/espresso-core-3.0.1.pom
