java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerExcep 错误

[youyiyang]

你好！
我在使用github上的一个开源项目， Android-Debug-Database的时候build报错 ：
Error:Execution failed for task ':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

这个项目主要是不用root就能在网页上调试sqllite数据库。
我的这个APP的gradle在下面：
project的 build.gradle:

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'

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

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

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

app的build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "27.0.0"

    defaultConfig {
        applicationId "com.example.eddieyou.iceboxmanager"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"

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

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

}

dependencies {

    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:23.4.0'
    implementation project(':debug-db')
    debugImplementation 'com.amitshekhar.android:debug-db:1.0.3'
}

debug-db的build.gradle:

请问上面哪里写的不对？
另外，我 参考了这篇博文，它也提到这个错误：
http://blog.csdn.net/o279642707/article/details/68946230
但是我不知道怎么排除这个错？
请大神指点一二！

Unable to merge dex 这个应该是告诉你有包冲突了. 具体是哪个包冲突了, 你需要仔细看错误提示.

[jklwan]

你的module和library的build.gradle中的版本要保持一致，如果基于27则全用27的版本，不能一个27，一个23，一个26；

compileSdkVersion 27
    buildToolsVersion "27.0.0"
 
    defaultConfig {

        minSdkVersion 14
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
 
    }
.........
compile 'com.android.support:appcompat-v7:27.1.0'
......

debug-db的build.gradle也按照这个改

问题找到了，是Android Support v4，v7包冲突问题。我首先加了"multiDexEnabled true"在defaultConfig 里面，然后就报错提示这个冲突问题。然后改成 “compile ('com.android.support:appcompat-v7:23.4.0'){ exclude module: 'support-v4' }” 就build通过了。 下面把我改好的3个build.gradle都发布一下吧： project的build.gradle:

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

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'

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

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

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