Android ADT版本22，R.java文件未生成 [英] Android ADT version 22, R.java files not generated

问题描述

升级到Android ADT版本22并清理我的项目后，R.java文件丢失。我不能使用setViewContent（R.layout.activity_main），因为活动无法引用xml布局（由于缺少R.java）。另外，当使用（ctrl + space）获取setContentView的建议时，不会输入代码。在查看错误日志时，会显示有一个未处理的事件循环异常。所涉及的插件是org.eclipse.ui。

After upgrading to Android ADT version 22 and cleaning my project, the R.java files went missing. I can't use setViewContent(R.layout.activity_main) because the activity cannot reference to the xml layout (due to the missing R.java). Also, when using the (ctrl + space) to get suggestions for setContentView, the code is not typed in. Upon looking at the error log, it shows that there was an "Unhandled event loop exception". The plug-in involved is the org.eclipse.ui.

此外，每当我创建一个新的Hello World项目时，gen文件夹为空。
经过几个小时，我试过android工作室。但我不喜欢那里。然后，当我回到Eclipse时，有一个SDK平台工具和构建工具的更新。我更新了他们，但我仍然收到错误。

Also, whenever I create a new Hello World project, the gen folder is empty. After a few hours, I tried the android studio. But I didn't like it there. Then, when I went back to Eclipse, there was an update for SDK platform tools and build tools. I updated them but I still get the errors.

我尝试清理项目，但没有运气。似乎有什么问题？

I tried cleaning the project but no luck. What seems to be the problem?
