将 .jar 文件添加到项目的问题

Question

添加了两个自定义 zxing 和 zbar 库，用于通过 File>New 读取和生成条形码更长而不是它的实现和api如何正确添加它们？

build.gradle（应用程序）

apply plugin: 'com.android.application'
check.dependsOn 'assembleDebugAndroidTest'

android {
compileSdkVersion 28
flavorDimensions "minSdkVersion"

defaultConfig {

    minSdkVersion 16
    targetSdkVersion 28
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner 
'android.support.test.runner.AndroidJUnitRunner'
}

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 
'proguard-rules.pro'
    }
}

compileOptions {
    sourceCompatibility 1.8
    targetCompatibility 1.8
}
}

configurations.all {
resolutionStrategy.force 'com.android.support:support-annotations:28.0.0'
}

dependencies {
implementation 'com.android.support:multidex:1.0.3'
implementation 'com.android.support.constraint:constraint-layout:1.1.3'

androidTestImplementation 'com.android.support.test:rules:1.0.2'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
implementation project(':zbar')
implementation project(':zxing_core')
}

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

build.gradle(项目)

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
repositories {
    jcenter()
    mavenLocal()
    google()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.3.2'
    classpath 'com.google.gms:google-services:4.2.0'
}
  }

allprojects {
repositories {
    mavenLocal()
    jcenter()
    google()
    maven { url 'https://maven.fabric.io/public' }
}
  }

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

我建议使用 https://mvnrepository.com/artifact/com.google.zxing 这里的依赖项，但在你的情况下（只要你添加 jars），你可以通过 implementation fileTree(include: ['*.jar'], dir: 'libs') 在 build.gradle 中插入它们（libs 可以替换为任何他们登陆的文件夹）。
