Question

我尝试同步gradle，但是我收到Gradle项目同步失败，基本功能可能无法正常工作。

这是我的应用gradle

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 27
    defaultConfig {
    applicationId "com.example.nawaf.fbm"
    minSdkVersion 16
    targetSdkVersion 27
    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"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1'
implementation 'com.android.support.constraint:constraint-layout:1.1.2'
implementation 'com.android.support:support-vector-drawable:27.1.1'
implementation 'com.android.support:support-v4:27.1.0'
implementation 'com.android.support:cardview-v7:27.1.0'
implementation 'com.android.support:customtabs:27.1.0'
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'

//anko
implementation "org.jetbrains.anko:anko:$anko_version"
implementation "org.jetbrains.anko:anko-design:$anko_version"
implementation "org.jetbrains.anko.anko-coroutines:$anko_version"

//firebase
implementation "com.google.firebase:firebase-core:11.8.0"
implementation "com.google.firebase:firebase-firestore:11.8.0"  
implementation "com.google.firebase:firebase-auth:11.8.0"
implementation "com.firebaseui:firebase-ui-auth:3.2.2"

kotlin {
    experimental {
        coroutines "enable"
    }
}
}

这是我在idea.log文件中遇到的错误

java.lang.NullPointerException

我正在使用Firebase制作消息应用程序

Answer 1

我认为kotlin-stdlib-jre7库已过时

替换

implementation"org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"

使用

implementation 'org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version'

注意：升级$ kotlin_version：1.2.51并重新同步Gradle

Gradle项目同步失败的Android Studio 3.1
