在Eclipse中，“源->格式在“ Maven Pom编辑器”中被禁用”

Question

[使用“ Maven Pom编辑器”在Eclipse中打开pom.xml并切换到选项卡pom.xml时，我无法格式化文件。

在完全未格式化的文件中命中Ctrl+Shift+F不会执行任何操作。通过上下文菜单Source -> Format时Format选项被禁用。

当我改用XML Editor打开文件时，格式化有效。

关于为什么可能会这样的任何想法？

我尝试过EMBEDDED Maven和外部版本3.5.2

Eclipse：

Eclipse IDE for Java Developers
Version: Oxygen.2 Release (4.7.2)
Build id: 20171218-0600

m2e Plugin 1.8.2

编辑[已解决]：

我在Package Explorer中右键单击了文件。在那里，源->格式已启用。单击它会导致异常：

在Eclipse中，无法再打开该文件。完全关闭编辑器并重新打开文件后，格式现在可以使用！

右键单击pom.xml文件，然后单击“格式”。
