Eclipse 说我没有编译错误 - 如何修复？

Question

我正在编写一个 java 项目，突然，eclipse 突然报告我的代码有问题。它特定于一个文件，但其他文件失败了，因为他们使用了相关类中的几个函数，他们似乎无法找到这些函数。我已经尝试了几乎所有我能想到的方法来消除这个错误。

• 刷新项目
• 清理项目
• 删除项目并重新导入
• 删除文件，新建，粘贴内容
• 删除错误并清理项目

具体来说第一个错误是：

Syntax error, insert "}" to complete ClassBody

只是为了说明，这里是代码：

编辑

是只有我还是有其他人收到此错误？

欢迎任何关于如何修复它的建议！

Answer 1

好的。我终于设法修复了错误。

如顶帖中的 cmets 所述，如果我清除构造函数，我可以编译它。一旦我得到它编译，我慢慢地将代码逐行复制粘贴到我的项目中。我省略了 ActionListeners，它编译得很好。在这之后我慢慢地一个一个地导入ActionListener方法，我找到了导致错误的一行。是这样的：

App.getSharedResources().changeRow(index, newRow); //line 106

这个方法还没有实现，在上面解释的过程之后它给了我一个错误。我可以创建该方法，并且我的其余代码现在可以按预期编译。这是一个非常奇怪的错误。

Answer 2

我过去也遇到过类似的问题，请您尝试从“问题”视图中删除错误，然后执行一个干净的项目，看看它是否消失。

如果没有帮助，请尝试：查看 .log 在您的工作区目录中创建的 .log 文件。这可能是如何解决这个问题的线索。
