Java 将现有项目复制粘贴到eclipse后失败

我正在尝试创建一个eshop，每次我完成某件事情时，我都会复制我的上一个项目并将其粘贴到同一个工作区（我在Eclipse中使用Maven、hibernate和MySQL）

今天，我有两个问题，我想得到你的帮助。我的上一个项目名为eMusicStore35。我无法运行此项目，因为我尚未完成我设计的所有方法

我在下一个名为eMusicStore37的项目中完成了它们（简单地复制eMusicStore35并用名称eMusicStore37粘贴它）

从图像中可以看到：

eMusicStore35有一个感叹号（！）。这意味着我的代码中有错误吗

eMusicStore37在ApplicationContext.xml和SprignMVC-servlet.xml处有错误。当我转到这些文件时，错误是相同的：

error occurred processing xml 'null'. see error log for more details

我试图寻找解决这个问题的办法，但没有成功

如果有人希望我上传更多文件以查找错误，请告诉我

编辑

第二个错误似乎已经解决了。我只想：

1。右键单击项目

我已多次尝试此，现在一切正常，因此无法理解之前的错误

对于第一个错误，我上传了下一张图片

但是现在，我看不到这个项目中有任何错误

此外，您只需在项目目录中选择并使用新名称粘贴项目即可克隆项目，这样您就可以并行工作，无需每次都执行复制粘贴。处理您想处理的项目。

感叹号（！）主要定义一些类路径问题。使用maven清理和构建。我右键单击我的项目，选择maven，更新项目。但一切都没有改变。对于这个感叹号（！）我还能做些什么？“这意味着我的代码中有错误？”这些错误是什么？仅仅说你有错误是完全没有用的。如果您不知道在哪里可以找到它们，请查看
