AndroidStudio升級後gradle配置出現的問題

                                                                       (可以 ctrl+F 搜尋 (需改動) 可以快速定位到要改動的位置)

專案的build.gradle裡面有改變

buildscript {
    repositories {
        google()     //(需改動)AS3.0以上這裡要配置
        jcenter()
    }
    dependencies {
//C:\Program Files\Android\Android Studio\gradle\m2repository\com\android\tools\build\gradle
 

//C:\Program Files\Android\Android Studio 你自己本機的Android Studio路徑(需改動)
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

allprojects {
    repositories {
        google()    //(需改動)AS3.0以上這裡要配置
        jcenter()
        maven { url "https://maven.google.com" }
        maven {
            url 'https://dl.bintray.com/oschinaapp/maven/'
 

        }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
ext {   //這個給module裡的build.gradle配置的常量
    compileSdkVersion = 26
    buildToolsVersion = "26.1.0"
    applicationId = "cn.cn.oschinadome"
    minSdkVersion = 19
    targetSdkVersion = 24
    versionCode = 288
    versionName = "v2.8.8(1708301525)"
 

    supportVersion = '25.1.0'
}

專案下的gradle檔案配置

project(專案目錄下)\gradle\wrapper\gradle-wrapper.properties

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip
#目錄:例如 C:\Users\MACHENIKE\.gradle\wrapper\dists 這個在你使用者目錄下的.gradle\wrapper\dists看有沒有
#3.5以上的gradle版本,gradle-4.4-all是我目錄下的
#也可以直接刪除gradle檔案,直接使用線上的gradle

module下的build.gradle檔案需要改動

apply plugin: 'com.android.application'
android {
    compileSdkVersion rootProject.ext.compileSdkVersion     //在專案中的build.gradle ext{}裡面
//   buildToolsVersion rootProject.ext.buildToolsVersion    //(需改動)在AS3.0以上不需要這個配置了

    defaultConfig {
        applicationId rootProject.ext.applicationId
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode rootProject.ext.versionCode
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        versionName rootProject.ext.versionName
//        jackOptions.enabled = true //(需改動) 如果你有這個需註釋掉
    }
    // rename the apk with the version name
//    applicationVariants.all { variant ->  //(需改動)AS3.0之後這個是隻讀,不能這樣修改apk的名字,需要註釋掉
//        variant.outputs.each { output ->
//            output.outputFile = new File(
//                    output.outputFile.parent + "/${variant.buildType.name}",
//                    "dome-osc-android-${variant.versionName}-${variant.buildType.name}.apk".toLowerCase())
//        }

    }

    sourceSets { //jni進入專案
        main {
            jniLibs.srcDirs = ['libs']
        }
    }

    // 移除lint檢查的error

}

dependencies {
    compile project(':open')      //open專案的引用
     //(需改動)這裡的所有 compile 變為 implementation或者api 
     //api(如果open裡引用裡另一個A專案,implementation的話不能使用A專案裡的介面,api的話就可以使用A專案的介面) 
     //Ctrl+R 快捷鍵 按鍵把  (compile ) 替換所有為 (implementation ) (區分大小寫)
