Why Does This Error Consistently Stay

Question

This error is getting annoying. Can someone please fix what's wrong. Thanks! Whenever I try to build the file. It gives me an error saying this: "[xX][mM][lL]" is not allowed. build.xml /HealPlayer line 1 Ant Buildfile Problem and this one: Element type "xml" must be followed by either attribute specifications, ">" or "/>". build.xml /HealPlayer line 1 XML Problem

 <?xml version="1.0" encoding="UTF-8" >

Answer 1

Change your first line to:

<?xml version="1.0" encoding="UTF-8"?>

Note: it needs to end in a question mark followed by a greater-than character.

You also need to make sure that the leading < is the first character in the file, i.e. no spaces in front of it.
