<condition property="file_has_lines_of_text"
value="true">
<resourcecount when="gt" count="0">
<tokens>
<file file="file_name.txt" />
</tokens>
</resourcecount>
</condition>
I admit I'm not sure how "file contains one or more
lines of text" differs from "file is not empty," so:
<condition property="file_is_not_empty" value="true">
<length file="file_name.txt" when="gt" length="0" />
</condition>
