我正在尝试运行appengineUpdate来部署我的后端，并且收到以下错误消息：
Failed to complete Gradle execution.
Cause:
Gradle build daemon disappeared unexpectedly (it may have been stopped, killed or may have crashed)
Gradle控制台有以下消息：
Configuration on demand is an incubating feature.
Relying on packaging to define the extension of the main artifact has been deprecated and is scheduled to be removed in Gradle 2.0

任何人都知道可能出现什么问题？
答案 0 :(得分：20)
对我有用的是：
设置 - ＆gt; Gradle - ＆gt; GradleVM选项 - ＆gt; 只需在框内添加：
-XX：MaxHeapSize = 256m -Xmx256m
答案 1 :(得分：7)
而不是@senimii建议作为vm选项，而是在 AndroidStudio-＆gt; Preferences-＆gt; Gradle 中使用以下内容：
<强> -XX：MaxPermSize参数=1024米
请参阅https://stackoverflow.com/a/12114284/954643，了解他们正在做什么。
答案 2 :(得分：3)
通过将以下内容添加到后端模块的build.gradle来解决它：
appengine {
downloadSdk = true
enhancerVersion = "v2" //http://stackoverflow.com/questions/23879156/trying-to-run-enhance-on-android-studio?noredirect=1#comment36798793_23879156
appcfg {
email = 'yourGmail'
password = 'yourGmailPW'
app {
id = 'themeviewersproject'
accessCode = 'yourAccessCodeHere'
}
oauth2 = false
}
我不确定哪些项目有效，因为我第一次能够评论所有内容（email / pw / id / accesscode）并且AS允许我继续更新后端。
编辑：重新启动后出现再次需要的项目，因此必须暂时存储它们。此外，这在命令行中效果最佳。
答案 3 :(得分：2)
这是属于Android Studio的错误。从控制台执行：
gradlew backend:appengineUpdate
我遇到了同样的错误，这解决了。（或者您可以使用电子邮件和密码确认）
