Question

我从Android Studio 3.1.4更新到了3.2。现在同步失败，并显示错误消息

未收到同步完成事件

如何解决？无效的缓存/重新启动没有帮助。

ida日志显示以下警告：

Answer 1

我发现的唯一解决方案是删除Android Studio并从头开始重新安装Android Studio 3.2。

Answer 2

编辑

该问题可能与OP不同，但这也是AS 3.2中的一个新问题，它会导致Gradle同步错误

在更新至AS 3.2之后的最后几天，我发生了Gradle同步错误，在我的情况下，问题是我的一个库模块之一在Manifest.xml中包含以下内容

 <uses-sdk
            android:minSdkVersion="15"
            android:targetSdkVersion="27" />

解决方案是删除项目中所有模块中的“ uses-sdk” （在AndroidManifest.xml文件中）。

Answer 3

尝试查看IDE的日志，就我而言，这是一个导致问题的插件。

您可以通过单击gradle中的show log导航到日志，然后在顶部重试条。

或

转到

~/username/Library/Logs/AndroidStudio3.5/

并阅读idea.log文件。

Answer 4

java.lang.NoClassDefFoundError： org / gradle / wrapper / WrapperConfiguration

似乎找不到WrapperConfiguration类。尝试以下命令：

brew install gradle
gradle wrapper

第二行将安装包装器类。然后

gradlew clean

更新后Android Studio 3.2同步失败
