我试图将android volley导入到我的项目中,但是失败了。我不知道发生了什么。这是build.gradle文件:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.root.wifi1"
        minSdkVersion 22
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support.constraint:constraint-layout:1.1.3'
    implementation 'com.android.volley:volley:1.1.1'

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

这是项目的build.gradle:

 buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

我已经尝试使用排球库版本1.1.1、1.1.0(来自mcxiaoke的版本)以及其他一些版本,但是它们都不起作用。我也尝试切换gradle版本,并尝试使用克隆的android volley创建本地库。有人建议将maven { url "https://jitpack.io" }添加到所有项目存储库中,我也尝试过,但是也没有用。当然,我也曾尝试从“设置”菜单禁用离线gradle,但是它并没有改变任何内容。

这是错误:

Unable to resolve dependency for ':app@debug/compileClasspath': Could not resolve com.android.volley:volley:1.1.1.
Unable to resolve dependency for ':app@debugAndroidTest/compileClasspath': Could not resolve com.android.volley:volley:1.1.1.
Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve com.android.volley:volley:1.1.1.

Unable to resolve dependency for ':app@releaseUnitTest/compileClasspath': Could not resolve com.android.volley:volley:1.1.1.

每次我更改排球版本时,错误也是如此。 我现在不知道该怎么办,请帮忙

PS:如果我评论/删除凌空依赖,我的项目可以100%正常运行,并且我不使用受代理保护的互联网

答案 0 :(得分:0)

尝试添加此

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

对于您的build.gradle,然后使Clean project也无效,缓存和从文件重新启动选项应该起作用。
