When opening the pom.xml in Eclipse using the "Maven Pom Editor" and switching to the tab pom.xml I cannot format the file.
Hitting Ctrl+Shift+F in an totally non-formatted file does not do anyting. When going via the context menu Source -> Format The Format option is disabled.
When I open the file in a XML Editor instead, the formatting works.
Any idea on why this could be the case?
I tried the EMBEDDED Maven and the external version 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
EDIT [SOLVED]:
I right clicked on the file in the Package Explorer. There, Source -> Format was enabled. Clicking it caused an Exception:
java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 2

within Eclipse and the file could not be opened anymore. After closing the editor completely and reopening the file the formatting now works!
