错误:无法解决:在android studio中常见

Question

我重新安装了android工作室,并在再次打开我的旧项目时显示以下错误:

Error:Failed to resolve: firebase-messaging
<a href="openFile:D:/Android projects/Porject_name/app/build.gradle">Open File</a>

Error:Failed to resolve: common
<a href="openFile:D:/Android projects/Porject_name/app/build.gradle">Open File</a>

build.gradle(Porject)文件:

// Top-level build file where you can add configuration options common to 

all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.3'
        classpath 'com.google.gms:google-services:3.1.0'

    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()

        google()


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

    }
}

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

build.gradle(app)文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 26
    buildToolsVersion '27.0.3'
    useLibrary 'org.apache.http.legacy'

    defaultConfig {
        applicationId "com.example.abc"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

}

    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    implementation 'de.hdodenhof:circleimageview:2.2.0'
    compile 'com.squareup.picasso:picasso:2.5.2'

}
apply plugin: 'com.google.gms.google-services'

我添加了所有必需的插件和sdk,但它仍然无法正常工作.安装了Firebase插件,即谷歌播放服务.在卸载工作室之前它工作正常.请帮忙.

Answer 1

将此maven {url" https://maven.google.com "} 添加/移动到build.gradle中的顶级矿工

Answer 2

这适合我.我只是按照这样重新排序

repositories {
    mavenCentral()
    mavenLocal()
    google()
    jcenter()
  }
