找不到com.android.support:appcompat-v7:25.3.1

Question

我在尝试构建时突然开始出现此错误.几周前这一切都在运作,我所知道的没有任何变化.这个问题似乎与此有关react-native-fbsdk,但通过它的build.gradle查看它没有列出support.appcompat-v7.25.x.有什么建议？

A problem occurred configuring project ':app'.
> A problem occurred configuring project ':react-native-fbsdk'.
   > Could not resolve all dependencies for configuration ':react-native-fbsdk:_debugCompile'.
      > Could not find com.android.support:appcompat-v7:25.3.1.

按照步骤，

1. 在项目 gradle ( Project: build.gradle) 中添加 google maven ，

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

2. cache使用以下命令删除现有的 gradle

   rm -fr ~/.gradle/caches/

3. 有一个干净的构建和运行

我在Android项目上遇到了同样的问题(appcompat-v7:25.3.1),但没有使用react.

我第一次尝试清理缓存的gradle(〜/ .gradle /高速缓存),如解释在这里,但它并没有帮助.

然后我查看了SDK Manager.
Android支持库通常通过sdkmanager安装.然后将这些库存储在本地maven存储库中:<SDK_HOME>/sdk/extras/android/m2repository/.

例如,对于appcompat-v7安装的版本列表<SDK_HOME>/sdk/extras/android/m2repository/com/android/support/appcompat-v7/maven-metadata.xml.
因此,对于Android支持存储库(版本:47.0.0),最后一个版本通常为25.3.1.

为了解决我的问题,我不得不通过SDK Manager 卸载 Android Support Repository,然后重新安装它.

我还找到了另一种获取支持库的方法:远程.在这里阅读(https://developer.android.com/topic/libraries/support-library/setup.html#add-library)并修改<PROJECT_ROOT>/build.gradle如下:

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

然后我尝试使用更新版本的appcompat-v7:25.4.0,它不在我当地的maven存储库中,并且它有效!
可以在此处查看此Google Maven存储库的此库版本列表:https://dl.google.com/dl/android/maven2/com/android/support/appcompat-v7/maven-metadata.xml.

我的情况是这是react-native-fbsdkbuild.gradle(https://github.com/facebook/react-native-fbsdk/blob/master/android/build.gradle):

apply plugin: 'com.android.library'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.1"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.1.0'
    compile 'com.facebook.react:react-native:+' // support react-native-v0.22-rc+
    compile('com.facebook.android:facebook-android-sdk:4.+')
}

我正在使用React Native 0.37,所以这就是为我打破的界限:

compile('com.facebook.android:facebook-android-sdk:4.+')

为了兼容性,不得不改为此:

compile('com.facebook.android:facebook-android-sdk:4.18.+')

为此，请尝试以下选项之一：

1.更新您的SDK manager> 转到构建菜单 > clean project> 然后build project

或者

2.右键单击项目文件夹>打开module setting>>libraries添加com.android.support:appcompat-v7:25.3.1>sync项目

3.单击file菜单 > 打开project structure> 并归档libraries
