就在几天前，我试图运行一个类，我收到了以下错误：

这在我之前没有发生，我没有更改任何XML文件。我试图运行其他类，只是为了获得相同的结果。我尝试了一切，包括重新启动IntelliJ甚至卸载和安装它，但错误不会停止。

我已经对这个错误进行了大量的研究，但它们似乎都不适合我的情况。任何人都可以帮我找出这个问题的过程吗？

注意：这里有一个类似的问题：Intellij IDEA crashed, and now throws an error

但是，我的Intellij IDEA没有崩溃，只是无法正常运行。

1 个答案:

答案 0 :(得分：0)

观察所描述的行为，我认为某些内容改变了.idea/runConfigurations中的一个文件。太糟糕了，您发布的错误消息不包含触发此错误的文件的文件名。使用文本编辑器检查.idea/runConfigurations中的文件，我希望你找到那里的罪魁祸首。

错误消息表示该文件不是格式良好的XML文件。更确切地说，这意味着该文件包含XML所说的内容＆＃34;内容＆＃34;在＆＃34;内容＆＃34;的位置不允许：在文档元素之前的文件开头的某处。该文件的开头在XML中称为 prolog 。

XML prolog 可能只包含以下内容：

  • 正好是一个XML声明，如果它出现必须是第一件事（只有字节顺序标记可能在XML声明之前），
  • 评论，例如<!-- foo -->
  • 处理说明，例如<?xml-stylesheet ... ?>
  • 空格（空格，换行符，制表符等）
  • 完全为零或一个DOCTYPE声明。

prolog 中的任何其他内容都会破坏XML文件，它将不再是XML，而是会出现您已经看到过的错误。

如果您无法手动修复此问题，即因为文件内容已消失或此类问题，您还可以执行以下操作：删除IntelliJ IDEA创建的所有文件，并通过从现有源导入来创建新项目。
