Question

所以我已更新到gradle 3.0.0（IDE也），它开始让我遇到各种各样的问题。
首先，我必须启用multiDex：

实现项目multidex vailError：任务执行失败＆＃39;：样品：transformDexArchiveWithExternalLibsDexMergerForDebug＆＃39 ;. ＆GT; java.lang.RuntimeException：java.lang.RuntimeException： com.android.builder.dexing.DexArchiveMergerException：无法合并 DEX

这很奇怪，因为这些是我唯一的依赖：

：样品

implementation project(':lib-module')
implementation "com.android.support:appcompat-v7:$rootProject.supportLibraryVersion"
implementation 'com.android.support.constraint:constraint-layout:1.0.2'

：lib-module

implementation "com.android.support:support-annotations:$rootProject.supportLibraryVersion"
    androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'junit:junit:4.12'

如果由于这些依赖关系我必须启用multiDex，默认情况下它也可能是真的...
启用后，我在：sample 模块中遇到了这个问题：

摇篮：

＆＃34;所有com.android.support库必须使用完全相同的版本规范（混合版本可能导致运行时崩溃）。发现版本27.0.0,21.0.3。＆＃34;

控制台：

java.io.IOException的：

不能写[build / intermediates / multi-dex / debug / componentClasses.jar]   （不能读   [... /建造/中间体/变换/ desugar /调试/ 14.jar（;;;;;; **。类）]   （重复的zip条目   [14.jar：机器人/支持/ V4 /视图/ ViewPager $ 1.class]））

所以我做了一些调查：

$ ./gradlew -q dependencies sample:dependencies --configuration debugAndroidTestCompileClasspath

我发现数据绑定导入support-v4 ...如果发生这种情况：com.android.support:support-annotations:21.0.3 -> 27.0.0（更新支持 - 注释版本）为什么不support-v4也得到更新？
所以我必须在：示例模块：

中添加此依赖项

implementation "com.android.support:support-v4:$rootProject.supportLibraryVersion"

从项目中删除所有构建文件夹和 .gradle 后，从用户/ .gradle缓存文件夹，运行Clean然后重建，我终于得到了一个.apk

为什么gradle和Android Studio 3.0.0会发生这种情况？谢谢你的时间。

===========================

编辑：感谢 Mark （@CommonsWare）comment我发现不仅是已知的问题，添加support-v4依赖项，不再需要multiDex。
