问题描述
我正在开发我的 Android 项目，删除未使用的库后，我收到 错误:
I am developing my Android project, After I removed a unused library, I got the error:
myproject/gen already exists but is not a source folder. Convert to a source folder or rename it
在我的 Activity 代码中，来自 R.java 的所有资源都无法解析.
In my Activity code, all resources from R.java can not be resolved.
我试过了，右键单击我的项目 => Java Build Path => 在源"选项卡下，我添加了 gen/作为源.但这对解决问题没有帮助...
I tried, right click on my project => Java Build Path => under "Source" tab, I added gen/ as source. But it does not help with the problem...
为什么，如何解决这个问题?
Why, how to get rid of this problem?
----更新----
我发现，eclipse还报错项目没有project.properties文件！编辑项目属性设置一个."，但我的项目下确实有 project.properties 文件.为什么会抱怨?我已经清理了项目并修复项目属性"，但没有帮助.
I found that, the eclipse also complain that "Project has no project.properties file! Edit the project properties to set one." , but I do have project.properties file under my project. Why it complains? I have cleaned the project and "fix project properties" but it does not help.

4.Click "Add Folder..." and check "gen" and "src"
第二个:(因为之前的操作要求我删除一些东西……我不记得是什么了……)
