android - 无法解析 io.reactivex.rxjava2 :rxjava:2. 2.0

Question

我以前没有使用过这个库，现在我尝试使用它并添加了所需的依赖项，但项目没有被同步。这是我的构建 gradle:

dependencies {
        implementation fileTree(dir: 'libs', include: ['*.jar'])

        // implement support libraries
        implementation 'com.android.support:appcompat-v7:27.0.2'
        implementation 'com.android.support:animated-vector-drawable:27.0.2'
        implementation 'com.android.support:design:27.0.2'
        implementation 'com.android.support.constraint:constraint-layout:1.1.3'
        implementation 'com.android.support:support-v4:27.0.2'

        // implement firebase libraries
        implementation 'com.google.firebase:firebase-auth:11.0.4'
        implementation 'com.google.firebase:firebase-database:11.0.4'
        implementation 'com.google.firebase:firebase-storage:11.0.4'
        implementation 'com.google.firebase:firebase-core:11.0.4'

        // implement firebase-ui
        implementation 'com.firebaseui:firebase-ui-database:2.3.0'

        // implement lifecycle
        implementation 'android.arch.lifecycle:extensions:1.1.0'

        // implement circle image view
        implementation 'de.hdodenhof:circleimageview:2.2.0'

        // implement image cropper
        implementation 'com.theartofdev.edmodo:android-image-cropper:2.7.0'

        // implement image compressor
        implementation 'id.zelory:compressor:2.1.0'

        // implement test
        testImplementation 'junit:junit:4.12'
    //    implementation 'io.reactivex.rxjava2:rxjava:2.1.5'
        implementation 'io.reactivex.rxjava2:rxjava:2.2.0'
    //    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    //    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'


    }



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

    configurations.all{
        resolutionStrategy.eachDependency{DependencyResolveDetails details ->
            def requested = details.requested
            if(requested.group == 'com.android.support'){
                if (!requested.name.startsWith("multidex")){
                    details.useVersion('27.0.2')
                }
            }
        }
    }

这个库在 github 和 ma​​ven 存储库 中可用

在build.gradle文件中的所有项目中添加这个存储库

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