Question

我正在将一个基于eclipse的旧项目移植到Android Studio（3.0.1）。

当我使用IDE在debug中编译时，一切正常，项目编译并在我的设备中成功运行。

但是，当我尝试使用以下命令在发行版中编译时，项目无法编译：

编译命令：

gradlew aR --stacktrace

错误：

我的gradle配置文件：

apply plugin: 'com.android.application'

    android {
        compileSdkVersion rootProject.ext.compileSdkVersion
        buildToolsVersion rootProject.ext.buildToolsVersion

        defaultConfig {
            applicationId "hhh"
            minSdkVersion rootProject.ext.minSdkVersion
            targetSdkVersion rootProject.ext.targetSdkVersion
            multiDexEnabled true
        }

        signingConfigs {
            release {

                storePassword 'xxxx'

            preDexLibraries = false //delete the already predexed libraries
        }

    }

        api fileTree(dir: 'libs', include: ['*.jar'])

有人对可能导致此问题的原因有一些提示或建议吗？

更新1：

在其中一个项目中有一些aidl文件，我们可以注意到，当我们尝试：

gradlew assembleDebug

项目正常编译。

但是当我们尝试：

gradlew assembleRelease

我们可以看到所有类都是在release文件夹中生成的，这些类是在debug中生成的，但是当然在debug文件夹中，并且找不到这些类：

class not found

Answer 1

有很多原因会显示“为dex处理返回代码1”。

基本上是说您的设置有问题（就像什么也没说）。

以下是一些可能的解决方案。

尝试清理或重建您的项目。
您有超过64k的方法-请参见here以启用多dex
您的某些库发生冲突。如果有一个组（例如com.google。*），请检查.gradle文件中的库版本。

由于您在版本中设置了minifyEnabled = false，因此可能是第二点。

在发布时编译时返回dex进程的代码1
