7.3. Catching Ant Build File Syntax Problems
Problem
You have a problem with a build file, and you would like to track it down.
Solution

only if your XML documents are not well formed in the XML sense
(e.g., nesting errors, omitting quotes for attribute values, etc.).
You can see an example in Figure 7-7, where
we’ve omitted the quote in front of the text
jarFile, which is being assigned to an attribute
in the <property> element.

Note, however, that although the Ant editor indicated that the XML
was not well formed, it entirely missed the fact that the
<property> element’s
name attribute is misspelled as
nane, as shown in the figure.
On the other hand, when you try to run this script, Ant will realize there’s a syntax error, and you’ll get the results you see in Figure 7-8, where the syntax error is indicated.
