Android Studio 0.4.3 – 根项目中没有找到任务“组合”

在另一天更新到0.4.3,并试图启动一个新的项目,甚至不使用现有的项目,我得到这个错误：

FAILURE: Build Failed with an exception.

What went wrong: Task ‘assemble’ not found in root project ‘XXX’.

Try: Run gradle tasks to get a list of available tasks. Run with –stacktrace option to get the stack trace. Run with –info or –debug option to get more log output.

这是我在日志文件中找到的：

这里是我的build.gradle文件(未触动)：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.8.+'
    }
}

allprojects {
    repositories {
        mavenCentral()
    }
}

我已经在线检查了几个帖子,但没有一个工作到目前为止.任何帮助将不胜感激.

解决方法

快速回答

删除组件标签之间的所有内容

<component name="FacetManager"> 
   ... <!-- remove all in this node 
</component>`

长回答

见http://tools.android.com/knownissues

If you get the following error message:

Gradle: 
FAILURE: Could not determine which tasks to execute.
* What went wrong:
Task 'assemble' not found in root project 'MyProject'.
* Try:
Run gradle tasks to get a list of available tasks.

The real problem is that prevIoUs version of Android Studio
misconfigured the IDEA file (e.g. MyProject.iml) — it added an extra
"<component name="FacetManager">" XML element that shouldn’t be
present.
In the case above,the solution is to edit “MyProject.iml”
and to remove the entire node <component name="FacetManager"> ... </component>

在您的具体项目称为XXX的情况下,您将寻求更正名为XXX.iml的文件

文档还说“或者,您可以删除项目的.idea文件夹和iml文件,并将您的源重新导入到新的Android Studio项目中.不是这个解决方案会为你而工作,因为你甚至不能得到一个新的项目来构建.
