gradle build 错误：任务'：core-app：dexDebug'的执行失败答案

【问题标题】：gradle build Error:Execution failed for task ':core-app:dexDebug'gradle build 错误：任务'：core-app：dexDebug'的执行失败

【问题描述】：

所以看起来我有一个传递依赖，我无法解决。我的核心应用程序模块依赖于另一个模块（B），另一个模块（A）也依赖于 B。像这样：

core-app depends_on module_B

core-app depends_on module_A

module_A depends_on module_B

搜索后我看到了这个解决方案：UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define 并尝试了这个：

configurations {
    all*.exclude group: 'my.package', module: ':module_B'
}

但是当我尝试运行应用程序时，我仍然遇到这个丑陋的错误：

Error:Execution failed for task ':core-app:dexDebug'.

有人知道我做错了什么吗？

好的，我想我找到了问题所在。 module_A 在将其更改为库 (apply plugin: 'com.android.library') 后被定义为应用程序 (apply plugin: 'com.android.application')，它似乎可以工作。在我看来这很奇怪。如果你们中的任何人有更好的解释，请不要犹豫分享。
