更新到 Android Studio 3.2 后，Gradle 同步失败，没有特定错误 - Android Gradle 插件 3.2.0

Question

我最近更新了 IDE，如果我按照建议将 Gradle 插件更新到版本 3.2.0，我将无法同步我的项目。 Android Studio 上的事件日志只报告Gradle sync failed。 我试过了：

• cleanBuildCache
• 重启
• 使 IDE 缓存无效
• 再做一次，以防万一

这是 IDEA 日志：

运行 ./gradlew build 构建成功，但 Studio 仍然抱怨 Gradle project sync failed 并且我无法运行东西。

Android Studio 3.2 / Android Gradle 插件 3.2.0 / Gradle 包装器 4.10.2 / MacOS High Sierra 10.13.4

任何形式的帮助都将不胜感激，谢谢。

Answer 1

我在使用全新的 gradle、gradle android 插件和 Android Studio 3.2 时遇到了同样的问题

我创建了一个单独的测试项目，并开始一个一个地移动我当前的项目模块，以识别同步问题。

在我的情况下，问题是由库清单文件中的 minSdkVersion 不匹配引起的。

在我的项目中，我有一堆在其清单文件中设置了 minSdkVersion 的 android 库。在以前的 gradle 插件/Android Studio 版本中，同步过程会忽略这些清单值，而倾向于使用 build.gradle 文件中定义的值。在新版本的 gradle plugin 中好像有问题。

我所做的：从库/应用清单中删除了所有 minSdkVersion/targetSdkVersion xml 条目。现在我的项目可以正确同步了。

希望能提供帮助。
