[android] Android 오류 : ': app : transformClassesWithDexForRelease'태스크에 대한 실행 실패

문제는 debug모드로 변경하면 앱을 실행할 수 있지만 release모드로 전환하면 실패한다는 것 입니다.

예외:

**FAILURE: Build failed with an exception.**
> Execution failed for task ':app:transformClassesWithDexForRelease'.
> com.android.build.api.transform.TransformException: com.android.ide.common.process.ProcessException: java.util.concurrent.ExecutionException: com.android.ide.common.process.ProcessException: org.gradle.process.internal.ExecException: Process 'command '/Library/Java/JavaVirtualMachines/jdk1.8.0_65.jdk/Contents/Home/bin/java'' finished with non-zero exit value 1

stacktrace로 gradle build 명령을 실행하면 이것이 내가 얻는 것입니다.

./gradlew app:transformClassesWithDexForRelease --stacktrace

릴리스 릴리스를 제거하면 작동시킬 수 minifyEnabled true있습니다. 그 이유는 무엇입니까, 다른 해결 방법이 있습니까?

답변

나는이 코드를 고쳤다.

local.properties

org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m

그리고 gradle 에서이 작업을 수행해야합니다

defaultConfig {
    applicationId "yourProjectPackage"
    minSdkVersion 15
    versionCode 1
    versionName "1.0"
    targetSdkVersion 23

    multiDexEnabled true //important
}

답변

당신이 만드는 경우 multiDexEnabled = true응용 프로그램의 defaultConfig, 당신은 원하는 결과를 얻을 것이다.

defaultConfig {
    minSdkVersion 14
    targetSdkVersion 22
    multiDexEnabled = true
}

답변

나를 위해 프로젝트에서 파일을 제거한 후 문제가 해결 되었습니다 jar. jar내 프로젝트 의 파일 중 하나가 이전 버전의을 사용하고있는 것 같습니다 google play services.

답변

나는 또한 같은 오류를 받았다 :

오류 : ‘: app : transformClassesWithDexForDebug’작업에 대한 실행이 실패했습니다. com.android.build.api.transform.TransformException : java.lang.RuntimeException : com.android.ide.common.process.ProcessException : java.util.concurrent.ExecutionException : com.android.ide.common.process.ProcessException : org.gradle.process.internal.ExecException : 프로세스 ‘command’C : \ Program Files \ Java \ jdk1.8.0_60 \ bin \ java.exe ‘가 0이 아닌 종료 값 1로 완료되었습니다.

잘 나는 다음 단계의 도움으로 이것을 고쳤다.

앱의 build.gradle (프로젝트 루트가 아닌)을 열고 다음을 추가하십시오.

android {
//snippet
//add this into your existing 'android' block

    dexOptions {
    javaMaxHeapSize "4g"
    }

//snip
}

빌드를 다시 시도하십시오.

참고 : 4g는 4 기가 바이트이며 이는 dex 작업의 최대 힙 크기입니다.

답변

MULTIDEX 불필요, 반복, MULTIDEX 불필요

자세히 설명하자면 : Multidex는 기본적으로 Android와 함께 제공되는 도구이며이를 true로 설정하면 64,000 개가 넘는 메서드가있는 앱은 약간 변경된 빌드 프로세스를 사용하여 컴파일 할 수 있습니다. 그러나 오류가 다음과 같은 경우에만 멀티 덱스를 사용해야합니다.

출력 쓰기 문제 : 너무 많은 필드 참조 : 131000; max는 65536입니다. –multi-dex 옵션을 사용해보십시오.

또는 이런

Dalvik 형식으로 변환하지 못했습니다 : dex를 실행할 수 없습니다 : [0, 0xffff]에없는 메소드 ID : 65536

그러나 그것은 아니다 여기서는 ! here (나를 위해) 문제는 build.gradle 파일의 종속성으로 인해 발생합니다.

해결책:
특정 종속성을 활용하십시오. 종속성의 전체 섹션을 가져 오지 마십시오!

예를 들어 위치에 대한 Play 서비스 종속성이 필요한 경우 가져 오기만 .

하다:

compile 'com.google.android.gms:play-services-location:11.0.4'

하지 말 것 :

compile 'com.google.android.gms:play-services'

이 문제를 일으킬 수있는 또 다른 문제는 사용중인 외부 라이브러리의 일종 일 수 있으며, 이는 이전 버전의 종속성을 참조합니다. 이 경우 다음 단계를 수행하십시오.

SDK 관리자로 이동하여 종속성 업데이트를 설치하십시오.
build.gradle 파일이 최신 버전을 표시하는지 확인하십시오. 최신 버전을 얻으려면 다음 링크를 사용하십시오.
https://developers.google.com/android/guides/setup
최신 버전을 참조하도록 라이브러리를 편집하거나 업데이트 된 버전이있는 경우 설치하십시오.

이 질문이 오래되었다는 것을 알고 있습니다. 앱의 수 잠재적으로 ANR의 원인이 아무 이유없이 multidex를 사용하기 때문에, 거기이 답변을 받으실 수 있습니다! 멀티 덱스가 필요한 경우에만 사용하고 그것이 무엇인지 이해 한 경우에만 사용하십시오.

나 자신도 멀티 덱스없이이 문제를 해결하기 위해 몇 시간을 보냈으며, 발견 한 내용을 공유하고 싶었습니다.

답변

앱 수준의 defaultConfig에 multiDexEnabled true 를 추가하십시오 gradle.

defaultConfig {
    applicationId "your application id"
    minSdkVersion 16
    targetSdkVersion 25
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner"android.support.test.runner.AndroidJUnitRunner"
    multiDexEnabled true
}

답변

내 앱에서 비슷한 문제가 발생했습니다. 여기 내가 한 일이 있습니다.

1. 모듈의 build.gradle에 이것을 추가하십시오 : app

multiDexEnabled = true

따라서 코드는 다음과 같습니다.

    android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "com.example..."
        minSdkVersion 17
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        multiDexEnabled = true
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

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

이것은 나를 위해 일했습니다. 희망이 당신에게도 도움이되기를 바랍니다 🙂

같은 프로젝트에서 Firebase 도 사용하고있었습니다 . 따라서 multiDexEnabled를 사용하면 Firebase for Lollipop 기기의 다른 문제가 발생할 수 있습니다 . 일부 FireBase 클래스가 식별되지 않았습니다. ( com.google.firebase.provider 공급자를 얻을 수 없음 ).
이를 해결하는 방법이 여기 에 설명되어 있습니다.
