Making jUnit output info and compile to /build folder

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?

PS. Those directories above (and build.xml) are all on new lines of course, so they are all on the same level — Vahagn, Aug 02 '11 at 12:48
When posting to SO, if you indent code - or whatever - by 4 spaces it will appear formatted as you typed it. You can use the curly brackets {} button in the Markdown editor bar to do the same. — martin clayton, Aug 02 '11 at 16:25

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.

Thanks for taking the time to answer, but I still don't understand the 'money' package deal. I don't have a 'money' package - just a folder named Money with the above folder structure. You say to have my classes under build I have to use the default package, what is that package? Thanks. — Vahagn, Aug 03 '11 at 07:16
The folder your .java files live in must match the `package` declaration at the top of the .java file. See edited answer. See also this question: http://stackoverflow.com/questions/1088509/what-is-the-purpose-of-defining-a-package-in-java-file — Danilo Piazzalunga, Aug 03 '11 at 17:05
