不久前，我为我的应用程序编写了一个库，其中包含2个模块：样本和库本身。
与往常一样，库模块包含在samples模块的build.gradle中，尽管它们都位于层次结构的同一级别，就在根目录之后：
----root
---samples
---tinyarbrowser
在第一次发布后，我使用了几周没有问题的项目。
昨晚我试图建立＆amp;运行 在轻微更新之前。所以......整个晚上都花在试图弄明白:) 主要问题是：
:samples:transformDexArchiveWithDexMergerForDebug FAILED
FAILURE: Build failed with an exception.
* What went wrong:

使用许多排除项和次要的传递依赖项来清理它 变化;
使缓存/重启/清除本地缓存文件无效;
implementation vs api vs compile;
针对小型lib的Multidex？:)试图确保，一切都一样;
将构建版本从3.1降级到3.0（D8与DX编译器）：在这种情况下，即使除了重要的Kotlin之外的所有依赖项，我都收到了UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define;
请参阅以下内容：
实际上，我90％肯定会对Kotlin有所了解，因为它的组件在两个模块中都被广泛使用，这是我不能做的最后一件事。 让我自己没有，所以我试图从样本模块中排除一切，除了Kotlin std＆＃39; s。 所以我也试过这个＆＃34;脏兮兮的伎俩＆＃34;：
tasks.whenTaskAdded {task ->
if(task.name.contains("transformDexArchiveWithDexMergerForDebug")) {
task.enabled = false
}
}
是的，那个版本实际上完成了，但是每次尝试在小米Redmi 4X上运行它时我都面临另一个问题：
Installation failed with message Failed to finalize session : INSTALL_FAILED_INVALID_APK:
Package couldn't be installed in /data/app/com.kkaun.tinyarbrowser-1: Package /data/app/com.kkaun.tinyarbrowser-1/base.apk code is missing.
It is possible that this issue is resolved by uninstalling an existing version of the apk if it is present, and then re-installing.
至于这个问题，我尝试禁用/重新启用Instant Run，关闭MIUI特定的开发功能，重新启动等等 - 它仍然是相同的。
出于选择，真实。但是，单个lib模块的项目结构改变才能正常运行。
任何有建设性的想法都将受到赞赏。

BUILD FAILED in 35s
答案 0 :(得分：2)
对于这个项目，构建工具最终会创建两个不同的BuildConfig.java文件 - 一个在samples模块中，另一个在tinyarbrowser模块中。它们都具有相同的com.kkaun.tinyarbrowser包。因为它们都在同一个包中，所以构建工具在合并期间会失败。
每个模块中的AndroidManifest.xml文件指示相应的BuildConfig类的位置，因此我们需要更改其中一个模块中的包，以便它们不会发生冲突。
例如，您可以从以下位置更新samples目录中的清单文件：
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.kkaun.tinyarbrowser">
到此：
<manifest
xmlns:android="http://schemas.android.com/apk/res/android"
package="com.kkaun.tinyarbrowser.samples">
这也意味着你需要改变一些课程。 samples模块中当前位于com.kkaun.tinyarbrowser下的类需要移至com.kkaun.tinyarbrowser.samples。
此外，还需要移动对资源的引用。例如，如果您这样做：
import com.kkaun.tinyarbrowser.R
然后需要更新到这个
import com.kkaun.tinyarbrowser.samples.R
可能还有一些其他需要更新的小型参考文献，但这应该可以帮到你。
