ANT Build Target is empty ???

Question

If I manually build an ant file the Build Target dialog box is empty? Why? Here is my build.xml file...
<?xml version = '1.0' encoding = 'windows-1252'?>
<!DOCTYPE project [
<!ENTITY common SYSTEM "file:./common-build.xml">
]>
<!--

The <empty> target list will appear whenever JDeveloper has trouble parsing the Ant XML document. In this case, it is because of the reference to the common-build.xml file. See the thread named "Building with Ant" in this forum, where this issue was recently discussed:
Re: How to bold a label ?
The end result of that discussion was that, due to a bug in JDeveloper, you need to specify the full URI to the included file. In a future release we will allow the use of relative URI's.
