problem encountered while trying to use ant to run findbugs.......

[fuel]

Greetings,
I have got a small problem while trying to run findbugs using
ant. The following shows the build file contents
==============================================
<?xml version="1.0"?>
<project default="findingBugs" name="SimpleProject">
<property name="findBugs.home" value="${user.home}/Desktop/
findbugs-1.0.0"/>
<property name="findBugs.experiment" value="${user.home}/bugs"/>

<taskdef name="FindBugs"
classname="edu.umd.cs.findbugs.anttask.FindBugsTask"/>
<echo message="${findBugs.experiment}/src/java"/>
<echo message="${findBugs.experiment}/src/java"/>

<target name="findingBugs" depends="compile">
<FindBugs home="${findBugs.home}" output="xml" outputFile="$
{user.home}/result.xml">
<class location="${findBugs.experiment}/bin" />
<sourcePath path="${findBugs.experiment}/src/java/" />
</FindBugs>
</target>

<target name="compile">
<javac srcdir="${findBugs.experiment}/src/java" destdir="$
{findBugs.experiment}/bin" />
</target>

</project>
==============================================================
After running the above build, even though i provide the "sourcePath",
findbugs output does not contain the lines at which the bugs are
found. The same happens when the output is in html format.
How do i resolve this issue ?

The source files for the project I am trying to run findbugs is @ " $
{user.home}/bugs/src/java "
and the generated class files are in the location " ${user.home}/bugs/
bin "

I am also pasting the output xml file. I hope its okay

I tried opening this file using the gui interface. However, it says no
source attached/found. Please let me know how to generate xml/html
output linked to source(line numbers)
thanks,

I have solved the problem. The problem was that ant by default
compiles java files with debug=off. If debug information is not
present, then the lines at which the errors occur cannot be
determined. However, after i changed the javac tag with debug="on", i
got all the information including the line number.
thank you!
