Problems With Apache Ant Tutorial - JUnit

I am trying to execute apache ANT:

http://ant.apache.org/manual/index.html

I am currently participating in JUnit, but keep getting errors related to being unable to find the junit.framework package.

I believe that I followed the textbook like this: here are the details:

----- My file structure -----

build.xml /build ../classes /lib ..log4j-1.2.8.jar myManifest /src ..HelloWorldTest.java ..log4j.properties ../oata ....HelloWorld.java

----- Sources -----

myManifest:

 Main-Class: oata.HelloWorld

build.xml

 <project name ="HelloWorld" basedir="." default="main"> <property name="src.dir" value="src" /> <property name="build.dir" value="build" /> <property name="classes.dir" value="${build.dir}/classes" /> <property name="jar.dir" value="${build.dir}/jar" /> <property name="lib.dir" value="lib" /> <path id="classpath"> <fileset dir="${lib.dir}" includes="**/*.jar" /> </path> <property name="main-class" value="oata.HelloWorld" /> <target name="clean"> <delete dir="${build.dir}"/> </target> <target name="compile"> <mkdir dir="${classes.dir}"/> <javac srcdir="${src.dir}" destdir="${classes.dir}" classpathref="classpath" /> <copy todir="${classes.dir}" > <fileset dir="${src.dir}" excludes="**/*.java" /> </copy> </target> <target name="jar" depends="compile"> <mkdir dir="${jar.dir}" /> <jar destfile="${jar.dir}/${ant.project.name}.jar" basedir="${classes.dir}"> <manifest> <attribute name="Main-Class" value="${main-class}" /> </manifest> </jar> </target> <target name="run" depends="jar"> <java fork="true" classname="${main-class}"> <classpath> <path refid="classpath"/> <path id="application" location="${jar.dir}/${ant.project.name}.jar"/> </classpath> </java> </target> <target name="junit" depends="jar"> <junit printsummary="yes"> <classpath> <path refid="classpath"/> <path refid="application"/> </classpath> <batchtest fork="yes"> <fileset dir="${src.dir}" includes="*Test.java"/> </batchtest> </junit> </target> <target name="clean-build" depends="clean,jar" /> <target name="main" depends="clean,run" /> </project>

HelloWorldTest.java:

 public class HelloWorldTest extends junit.framework.TestCase { public void testNothing() { } public void testWillAlwaysFail() { fail("An error message"); } }

HelloWorld.java

 package oata; import org.apache.log4j.Logger; public class HelloWorld { static Logger logger = Logger.getLogger(HelloWorld.class); public static void main(String [] args){ logger.info("Hello World!"); } }

log4j.properties:

 log4j.rootLogger=DEBUG, stdout log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%m%n

Is there something I am missing that needs to be included, which was (or was not) mentioned in the textbook?

EDIT . Based on Alex polls, I tested if I have ANT junit jars in my shared directories (what I do):

 $ ls /usr/share/ant/lib/ant-junit*.jar /usr/share/ant/lib/ant-junit.jar /usr/share/ant/lib/ant-junit4.jar

I also tried manually putting ant -junit, ant -junit4.jar and junit.jar in the directory of my lib project with the following results (all errors) after running ant clean JUnit

  • junit.jar - / Users / jtyler / Projects / AntHelloWorld / build.xml: 45: Link not found.
  • ant -junit.jar: junit.framework package does not exist
  • ant -junit.jar and ant.junit4.jar: junit.framework package does not exist
  • ant -junit4.jar: junit.framework package does not exist

EDIT All error when only junit.jar is included in the lib folder and the call to ant clean junit is called :

 $ ant clean junit Buildfile: /Users/jtyler/Projects/AntHelloWorld/build.xml clean: [delete] Deleting directory /Users/jtyler/Projects/AntHelloWorld/build compile: [mkdir] Created dir: /Users/jtyler/Projects/AntHelloWorld/build/classes [javac] /Users/jtyler/Projects/AntHelloWorld/build.xml:20: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds [javac] Compiling 2 source files to /Users/jtyler/Projects/AntHelloWorld/build/classes [copy] Copying 1 file to /Users/jtyler/Projects/AntHelloWorld/build/classes jar: [mkdir] Created dir: /Users/jtyler/Projects/AntHelloWorld/build/jar [jar] Building jar: /Users/jtyler/Projects/AntHelloWorld/build/jar/HelloWorld.jar junit: BUILD FAILED /Users/jtyler/Projects/AntHelloWorld/build.xml:45: Reference application not found.

Besides the junit.jar file in my lib directory, I added the following line to my build.xml file right above the junit task declaration:

 <path id="application" location="${jar.dir}/${ant.project.name}.jar"/>

which is a copy of the application path identifier declaration, in the definition of the "run" task.

The application works successfully, and I get the following output with ant junit (expected to fail during testing):

 ant junit Buildfile: /Users/jtyler/Projects/AntHelloWorld/build.xml compile: [javac] /Users/jtyler/Projects/AntHelloWorld/build.xml:20: warning: 'includeantruntime' was not set, defaulting to build.sysclasspath=last; set to false for repeatable builds jar: junit: [junit] Running HelloWorldTest [junit] Tests run: 2, Failures: 1, Errors: 0, Time elapsed: 0.001 sec [junit] Test HelloWorldTest FAILED BUILD SUCCESSFUL Total time: 1 second

Comments will be welcomed with the following questions:

  • I really need to include the junit.jar file in the lib folder, what should I worry about? I would suggest that this is not necessary if the ant tutorial explicitly states: "Since ant has built-in JUnit 3.8.2, you can start using it directly."

  • Is the fact that I need to determine the identifier of the path "application" outside of the definition of the startup task a typo in the apache ant tutorial? Or are there other things that I missed or should consider?

Thanks to everyone who helped.

The textbook is misleading. The junit files included in ant do not work. I downloaded juinit and copied the jar file to the lib folder of the project, and now it works fine.

You must specify junit.jar yourself in your compilation and in your path to the <junit> task class. This will not be automatically included in your compiler:

 <!-- Contains junit.jar and other needed test classes --> <path id="junit.classpath"> <fileset dir="${junit.directory}"/> </path> <!-- Contains third party jars your code is dependent upon --> <path id="main.classpath"> <fileset dir="${dependent.jar.dir}"/> </path> <!-- Your main Java source code directory --> <property name="main.srcdir" value="${basedir}/src/main/java"/> <!-- Your main Junit test directory source code --> <property name="test.srcdir" value="${basedir}/src/test/java"/> <!-- Where you're compiling your main classes to --> <property name="main.destdir" value="${basedir}/target/classes"/> <!-- Where you're compiling your test classes to --> <property name="test.destdir" value="${basedir}/target/test-classes"/> [...] <!-- Compile Test Classes --> <!-- Notice you have three classpath elements: * Your main classes you compiled before * Your test main classpath that your main classes were dependent up * The junit.jar classpath --> <javac destdir="${test.destdir}" srcdir="${test.srcdir}"> <classpath> <!-- Your non-test classes you compiled before --> <pathelement path="${main.destdir}/> </classpath> <classpath refid="junit.classpath"/> <classpath refid="main.classpath"/> </javac> <!-- Now run your unit tests: Note how you have the same three classpath elements as before --> <junit fork="yes"> <classpath> <pathelement path="${main.destdir}"/> <pathelement path="${test.destdir}"/> </classpath> <classpath refid="main.classpath"/> <classpath refid="junit.classpath"/> [...] </junit>
