Gradle错误升级到Android Studio 3.0 Beta 1

注意：这似乎是Android插件的问题.查看相关问题的评论.

构建项目时出现以下gradle错误：

Gradle sync Failed: Cause: java.lang.NullPointerException

我还要注意,我必须手动设置jdk位置,因为如果我使用捆绑的那个gradle守护程序将无法启动,抱怨不在预期的上下文中(它期望捆绑的上下文,而是获取外部上下文).

这种配置在金丝雀9中工作(使用捆绑的jdk).

解决方法:

归功于@Grsmto

根据this blog post,您需要打开终端并按顺序启动以下命令：

UPDATE

Now the workaround it’s easier, you just need to go to Build -> Clean Project and then sync.

视窗

gradlew清洁

gradlew组装

Linux的/苹果机

./gradlew清洁

./gradlew汇编

然后同步项目.
