Question

我不小心删除了我的gen文件夹，现在，可以预见，我的资源都搞砸了。我自己创建了一个gen文件夹并尝试投影＆gt;干净 - 没用。尝试右键单击项目并转到Android工具＆gt;修复项目属性 - 没有用。尝试自动取消检查构建...不起作用。清理，关闭项目，关闭日食，重新启动等等。没有任何工作，我一直看到这个错误：gen already exists but is not a source folder. Convert to a source folder or rename it.

编辑 - 确定能够生成R.java，但现在我在控制台中变得疯狂了：

Ill-advised or mistaken usage of a core class (java.* or javax.*)
when not building a core library.

This is often due to inadvertently including a core library file
in your application's project, when using an IDE (such as
Eclipse). If you are sure you're not intentionally defining a
core class, then this is the most likely explanation of what's
going on.

However, you might actually be trying to define a class in a core
namespace, the source of which you may have taken, for example,
from a non-Android virtual machine project. This will most
assuredly not work. At a minimum, it jeopardizes the
compatibility of your app with future versions of the platform.
It is also often of questionable legality.

If you really intend to build a core library -- which is only
appropriate as part of creating a full virtual machine
distribution, as opposed to compiling an application -- then use
the "--core-library" option to suppress this error message.

If you go ahead and use "--core-library" but are in fact
building an application, then be forewarned that your application
will still fail to build or run, at some point. Please be
prepared for angry customers who find, for example, that your
application ceases to function once they upgrade their operating
system. You will be to blame for this problem.

If you are legitimately using some code that happens to be in a
core package, then the easiest safe alternative you have is to
repackage that code. That is, move the classes in question into
your own package namespace. This means that they will never be in
conflict with core system classes. JarJar is a tool that may help
you in this endeavor. If you find that you cannot do this, then
that is an indication that the path you are on will ultimately
lead to pain, suffering, grief, and lamentation.

Answer 1

右键单击您的项目
选择属性。
选择Java Build Path
点击添加文件夹
选择gen文件夹
单击“确定”。

Answer 2

我不知道这是否有资格作为答案，但我最终举手并恢复了我的最后一次提交。

Answer 3

我将SDK升级到v22并将ADT升级到更新版本后，今天遇到了同样的问题。显然我的SDK Manager没有检测到SDK Platform-Tools和新推出的SDK Build-tools也发生了变化，所以它没有升级工具，导致我的SDK / ADT包没有生成/ gen文件夹的内容蚀。

升级SDK和ADT之后我不得不回到SDK管理器，这样我就可以选择安装/更新SDK平台工具到17（从16我有）和SDK Build-tools（也是17）

Answer 4

R类的编写可能存在问题（例如，由于某些布局xml中的错误）。从“首选项”中将构建器输出转换为“详细”，然后在生成中断的控制台中查看。

删除了gen文件夹，eclipse现在没有生成它:(
