android - 无法解析 com.android.tools.build.gradle :3. 0.1

Question

我正在强制 gradle 使用 http我已经修改了我的 gradle-wrapper.properties:

distributionUrl=http\://services.gradle.org/distributions/gradle-4.3-all.zip

build.gradle:

buildscript {
repositories {
    //jcenter()
    //google()
    maven { url "http://jcenter.bintray.com"}     
    }
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}}

allprojects {
repositories {
    jcenter()
    maven { url 'http://maven.google.com' }
    maven { url "http://jitpack.io" }
}}

据我所知，我应该使用 3.0.1，但是当我检查 jitpack 或 maven 上的实际存储库时，只有 2.3.3 可用。

我得到的错误信息是:

> Could not resolve all files for configuration ':classpath'.
> Could not find com.android.tools.build:gradle:3.0.1.
Searched in the following locations:
http://jcenter.bintray.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom
http://jcenter.bintray.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.jar
Required by:
     project :* Try:

Gradle 版本是 4.3.1 JVM 9.0.1

如何在此处成功运行“gradle test”？

编辑:取消注释//google() Revel :

       > Could not get resource 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom'.
        > Could not GET 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom'.

修改http repo时

buildscript {
repositories {
    //jcenter()
    //google()
    maven { url "http://jcenter.bintray.com"}
    maven { url "http://maven.google.com"}

    }

我明白了:

      > Could not resolve com.android.tools.build:gradle:3.0.1.
     > Could not get resource 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom'.
        > Could not GET 'https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom'.
           > sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
  > Could not resolve com.android.tools.build:gradle:3.0.1.
     > Could not get resource 'http://maven.google.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom'.
        > Could not GET 'http://maven.google.com/com/android/tools/build/gradle/3.0.1/gradle-3.0.1.pom'.
           > sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

如果我取消注释 jcenter() 和 google()，我会得到相同的结果。此外，当我检查 https://dl.google.com/dl/android/maven2/com/android/tools/build/gradle/链接已失效。现在 jcenter repo https://repo1.maven.org/maven2/com/android/tools/build/gradle/结束于 2.3.3 版本，这似乎是正确的，这个错误正在发生，问题是出了什么问题？

编辑- 问题发生的可能解决方案是因为您无法完全运行除 https 之外的那些，无论哪种方式都会失败。

Answer 1

Could not resolve com.android.tools.build:gradle:3.0.1.

阅读 Google's Maven repository

在您的 顶级 build.gradle 文件中包含 Google 的 Maven 存储库:

仅供引用

allprojects {
    repositories {
        google()

        // If you're using a version of Gradle lower than 4.1, you must instead use:
        // maven {
        //     url 'https://maven.google.com'
        // }
        // An alternative URL is 'https://dl.google.com/dl/android/maven2/'
    }
}

所以，根据您的版本，您的 build.gradle 将

buildscript 
{

    repositories {
        jcenter()
        google()
        maven { url "http://jcenter.bintray.com"}     
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'

    }
}

allprojects 
{
    repositories {
        jcenter()
        maven { url "https://jitpack.io" }
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
