Eclipse：创建新的JavaScript文件错误

Question

首先，我在GitHub中创建了一个项目，使用Egit将其导入Eclipse（kepler），并使其成为一个JavaScript项目（使用标准的javascript插件）。我在这个项目上工作没问题。我将整个项目（包括.project文件等）推送到GitHub。

现在，当我在另一台计算机上导入这个项目时，事情变得奇怪了。我使用Egit从GitHub存储库导入它。然后我使用导入作为现有项目，因为我上传了所有项目文件。现在这很好用，直到我想创建一个新的JavaScript文件。

当我这样做时，新建一个新的JavaScript文件。窗口apears，但是当我输入名称时，“完成”按钮保持禁用状态。此外，当我单击其中一个父文件夹时，我得到一个nullpointer异常：

谁能告诉我这里我做错了什么？这是一个错误吗？我不能只在不同的电脑上导入其他项目吗？或者git出了什么问题？

以下是错误日志：

从插件调用代码时出现问题：“org.eclipse.jface”。

Answer 1

当我采取下一步措施时，问题不会发生：

• 使用Git导入项目（排除项目文件）
• 将项目添加为常规项目
• 将其转换为JavaScript项目。

这已经解决了我的问题，但我仍然想知道我用其他方法做错了什么。
