我无法再通过 Eclipse 中的向导创建“App Engine Connected Android Project”。当我单击“完成”按钮时，出现以下错误消息：
创建元素失败。
com.android.ide.eclipse.adt.internal.project.AndroidNature.setupProjectNatures(Lorg/eclipse/core/resources/IProject;Lorg/eclipse/core/runtime/IProgressMonitor;)V
我用：
- 视窗 7 (x64)
- 日食朱诺 4.2
- jre7
- 谷歌应用引擎 SDK 1.8.0。
- Android SDK API 8 和 17
这是一个全新的安装。在新安装 Eclipse 之前，它可以工作。我还为“项目编号”和“API 密钥”插入了正确的值。
该向导仅创建一个名为“.project”的文件，其内容如下：
<?xml version="1.0" encoding="UTF-8"?>
<projectDescription>
<name>Test</name>
<comment></comment>
<projects>
</projects>
<buildSpec>
</buildSpec>
<natures>
</natures>
</projectDescription>
异常堆栈跟踪：
