Android Studio maven { url "https://jitpack.io" } 无法下载

Question

不能再使用maven { url "https://jitpack.io" }。我有以下 gradle：

apply plugin: 'com.android.application'


android {
    compileSdkVersion 27

    defaultConfig {
        applicationId "test.com.myapplication"
        minSdkVersion 19
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.+'
}

尝试构建时出现错误：

Answer 1

天哪，终于明白了！

所以我不得不像jitpack official site 中提到的那样使用它：

maven { url 'https://www.jitpack.io' }

但我只是从jitpack github复制/粘贴它：

maven { url 'https://jitpack.io' }

Answer 2

打开settings.gradle文件，在repositories里面添加下面一行（如上图）

        maven { url "https://jitpack.io" }

并从项目的 build.gradle 文件中删除下面的代码

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

Answer 3

花了几分钟搜索并意识到当您使用 Kotlin DSL 构建 build.gradle.kts 时，存储库信息应该是 Kotlin 格式：

repositories {
  maven { url = uri("https://www.jitpack.io" ) }
}

Answer 4

因为jitpack 是您添加的唯一存储库。您还需要像这样添加 Google 的存储库：

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

顺便说一句，只是一些提示：

• 指定您使用的库版本。 （所以不要写:27.+）
• 将您的allprojects 函数放入您的项目级gradle 中。 (项目/build.gradle)
