无法解决 'com.google.firebase:firebase-auth:16.0.3' 的依赖关系
Could not resolve dependency for 'com.google.firebase:firebase-auth:16.0.3'
我正在尝试将 firebase 身份验证添加到我的项目中。同步 build.gradle
:
时出现以下错误
Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.google.firebase:firebase-auth:16.0.3.
Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.google.firebase:firebase-auth:16.0.3.

我的应用级别 gradle 文件如下:

项目级别 gradle 文件是:
buildscript {

classpath 'com.google.gms:google-services:4.0.1'

jcenter()
maven { url 'https://jitpack.io' }

}
task clean(type: Delete) {
delete rootProject.buildDir
}
在 project level gradle
文件中尝试将 google-services 插件 更新到最新版本:
buildscript {
repositories {
google()
jcenter()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.1.0' // update version
}
}
它抱怨 debugUnitTest
缺少依赖项,而您在模块级别 build.gradle
中没有指定任何 debug
构建类型。它应该看起来像这样,例如:
buildTypes {
debug {
applicationIdSuffix '.debug'
// signingConfig signingConfigs.debug
minifyEnabled false
debuggable true
jniDebuggable true
zipAlignEnabled true
renderscriptDebuggable true
pseudoLocalesEnabled false
shrinkResources false
}
此外,考虑将 androidTestImplementation "com.android.support.test:rules:1.0.2"
添加为依赖项...并可能将 testBuildType "debug"
添加到 defaultConfig
。
由于正常方式不起作用,假设您使用的是 Android Studio,您可以通过以下方式尝试使用 GUI 方式:
- 清理项目
- 重建项目
- 下
Tools
、select Firebase
- 身份验证
- 电子邮件和密码验证
- 连接到 Firebase
- 添加依赖项
- 按照说明检查您的身份验证状态
