Question

Hey guys I’ve been trying all day to get an ant file to automatically build my project. The file (appended below) was on a web page I found and is pretty thorough.

My problem is that it works as long as I don’t run the “clean” target. Once the I run the “clean” target the “test” target ceases to work. I get NoClassFound errors on all test classes. Even though it worked earlier.

I’m working on a Macbook (10.5.8) using the latest version of eclipse. This error occurs running the file from eclipse and from a terminal using Ant version 1.7.1

I modified the file slightly to adapt it to my file structure which is as follows:

src/
   packageA.packageB/
                     ClassA.java
                     ...
                     ClassN.java

unittests/
          packageA.packageB/
                            AllClassTests.java
                            ClassATest.java
                            ...
                            ClassNTest.java

lib/
    junit-4.7.jar

The ant file is:

<project name="SampleJUnitTests" default="dist" basedir=".">
<description>
    DataTypes Build File

<!-- set global properties for this build -->

I give up and hope that someone can shine a light on my problem.
Thanks a lot!

You haven’t got any Ant target which builds the test classes. You could do this as part of the compile target if you wanted:

<target name="compile" depends="init" description="compile the source code " >
  <javac srcdir="${src}" destdir="${build}">
    <classpath>
      <fileset dir="lib">
        <include name="**/*.jar"/>
      </fileset>
    </classpath>
  </javac>
  <javac srcdir="${tests}" destdir="${build}">
    <classpath>
      <pathelement path="${build}"/>
      <fileset dir="lib">
        <include name="**/*.jar"/>
      </fileset>
    </classpath>
  </javac>
</target>
