Question

我遇到以下错误

无法获得类型对象的未知属性'supportLibVersion' org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHand

我正在开发react-native应用程序，并且react-native-maps依赖项在下面出现错误

 dependencies {
      def supportLibMajorVersion = supportLibVersion.split('\\.')[0] as int
      def appCompatLibName =  (supportLibMajorVersion < 20) ? "androidx.appcompat:appcompat" : "com.android.support:appcompat-v7"
      implementation "$appCompatLibName:$supportLibVersion"
      implementation('com.facebook.react:react-native:+') {
        exclude group: 'com.android.support'
      }
      implementation "com.google.android.gms:play-services-base:${safeExtGet('playServicesVersion', '16.1.0')}"
      implementation "com.google.android.gms:play-services-maps:${safeExtGet('playServicesVersion', '16.1.0')}"
      implementation 'com.google.maps.android:android-maps-utils:0.5'
    }

任何人都可以知道这里出了什么问题吗？

终端错误是

失败：生成失败，发生异常。

位置：
  构建文件'D：\ react native \ abhishek \ Gwala \ node_modules \ react-native-maps \ lib \ android \ build.gradle'行：20

出了什么问题：
  评估项目'：react-native-maps'时发生问题。
  无法获得类型为org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler的对象的未知属性'supportLibVersion'。

第20行是

def supportLibMajorVersion = supportLibVersion.split('\\.')[0] as int

Answer 1

在supportLibVersion = "28.0.0"内添加android/build.gradle-> ext

示例：

ext {
  buildToolsVersion = "28.0.3"
  minSdkVersion = 16
  compileSdkVersion = 28
  targetSdkVersion = 28
  supportLibVersion = "28.0.0"
}

Answer 2

在supportLibVersion = "28.0.0"中的buildscript中添加android/build.gradle

buildscript {
    ext {
        buildToolsVersion = "28.0.3"
        minSdkVersion = 16
        compileSdkVersion = 28
        targetSdkVersion = 28
        supportLibVersion = "28.0.0"  // <=== add this line
    }

    ...
}

Answer 3

尝试直接从github安装它：

npm install --save git+https://git@github.com/react-native-community/react-native-maps.git

Answer 4

这些步骤之后，我解决了这个问题：

将此行添加到\node_modules\react-native-maps\lib\android\build.gradle -- line: 20

def supportLibVersion = safeExtGet('supportLibVersion', '28.0.0')
在AndroidManifest.xml下的<application>中：

<uses-library android:name="org.apache.http.legacy" android:required="false"/>

Answer 5

在android目录中的文件build.gradle中

（... / YourApp / android / build.gradle）

找到ext部分并添加

supportLibVersion =“ 28.0.0” ext { ... supportLibVersion =“ 28.0.0”}

应该完成的工作。

Answer 6

在node_modules/react-native-maps/lib/android/build.gradle中添加以下行：

在dependencies下

def supportLibVersion = safeExtGet('supportLibVersion', '28.0.0')

示例：
https://github.com/react-native-community/react-native-maps/blob/master/lib/android/build.gradle
