Making jUnit output info and compile to /build folder - ant

Question

I have the following Ant buildfile:
<?xml version="1.0"?>
<!-- the value of the default attr must be one of the targets. -->
<project name="Money" default="build-source" basedir=".">
<description>The Money project build file.</description>
<property name="src" location="."/>
<property name="build" location="build"/>
<property name="junit" location="lib/junit-4.9b3.jar"/>
<path id="_classpath">
<pathelement path="${junit}"/>
<pathelement path="${build}"/>
</path>
<target name="prepare">
<mkdir dir="${build}"/>
</target>
<target name="build-source" depends="prepare"
description="compile the source ">
<javac srcdir="${src}" destdir="${build}">
<classpath refid="_classpath"/>
</javac>
</target>
<target name="run" depends="build-source">
<junit printsummary="on" showoutput="on">
<test name="money.MoneyTest"/>
<classpath refid="_classpath"/>
</junit>
</target>
</project>
It's pretty basic - I'm just trying to get this thing to run properly. What I don't get is: 1) Why does it output the compiled files to a /build/money directory? I want the output directory to be just /build, given this directory structure for my files:
build/
build.xml
lib/
src/
test/
2) When there are tests that don't pass, it says "Test money.MoneyTest FAILED". I'd like it to output info about the failure, expected / actual values, line number, etc.
I can't figure this out by staring at the buildfile above. Any advice?

Answer 1

It outputs the compiled files under build, creating a directory structure that corresponds to the layout of your packages.
Since you put your classes in the money package, the output will be under build/money. If you put your classes under a org.example.foo package, your output would be in the build/org/example/foo directory.
To have your .class files in build, you would have to use the default package.
Edit
I assume your source files have a package money; declaration, as in:
package money;
public class MoneyTest {
...
}
If you add a <formatter> element, detailed reports about test failures will be written to an output file (by default, named TEST-name). See also the Ant Junit Task Documentation.
<junit printsummary="withOutAndErr" showoutput="on">
<formatter type="plain"/>
<test name="money.MoneyTest"/>
<classpath refid="_classpath"/>
</junit>
I have not found a way to directly print the failed tests reports to standard output.
