============更新=============
我能够一次一个地手动编辑我的应用程序中的所有18个类，并以新名称发布，但这不是一个真正可接受的长期解决方案。我仍然想知道如何解决这个问题。正如我所说，我能够更改其他应用程序的包名称，而不是我关心的那个。

我转到“应用程序工具”然后“重命名应用程序项目”，我可以重命名一个包，除了我要重命名的包。在那种情况下，我得到一个例外：
弹出的框称为重构
框中的标题为执行重构时发生致命错误。
错误信息是：
“创建更改对象时发生意外异常。有关详细信息，请参阅错误日志。”
错误日志中没有显示任何内容，我不知道该怎么做。我可以轻松地重命名其他项目，所以我想我知道这个过程。该应用程序运行正常，实际上已在Google Play上发布。我想创建第二个版本用于测试，在10天内超时，供人们尝试，因此需要一个不同的名称。只是更改字符串文件中的名称是不足以让Google Play认为它是一个不同的项目。
几乎任何可以将这个东西作为不同的应用程序在Google Play上运行的工作都可以。
任何帮助都会受到赞赏，因为大多数帖子都涉及在没有错误时如何更改名称，我可以这样做。

我的问题是因为我有一个完全注释掉的代码文件，当re factor工具扫描我的包下的文件时，它无法读取它。检查您的代码，确保.java文件都是有效的java文件。

重新安装Eclipse。没有其他工作。
