junit task not working
<LOOP times="999999999999" message="PLEASE HELP !!!" />
I am running ant (1.4 and 1.5b2) on win98 , the build did'n work on 1.4 so
I reached out for 1.5 and it's not working either.
I have a target called "junit" :
....................
<target name="junit" description="Performs all JUnit regression tests." >
<junit printsummary="yes" fork="yes" dir="${build.test}/ojb">
<classpath refid="runtime-classpath"/>
<formatter type="plain" />
<test name="test.ojb.broker.AllTests"
haltonfailure="no"
outfile="target/test/tests-broker" >
</test>
<test name="test.ojb.odmg.AllTests"
haltonfailure="no"
outfile="target/test/tests-odmg" >
</test>
<test name="test.ojb.soda.AllTests"
haltonfailure="no"
outfile="target/test/tests-soda" >
</test>
</junit>
</target>
...................
on that target I get printout like :
..................
junit:
BUILD FAILED
C:\java\ojb9\build.xml:407: Could not create task or type of type: junit.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
- You have misspelt 'junit'.
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
- The task is an Ant optional task and optional.jar is absent
Fix: look for optional.jar in ANT_HOME/lib, download if needed
- The task was not built into optional.jar as dependent
libraries were not found at build time.
Fix: look in the JAR to verify, then rebuild with the needed
libraries, or download a release version from apache.org
- The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
............................
So I tried to fix things by manualy defining taskdef for "junit" task.
At the beginning of the build.xml I added :
<taskdef name="junit"
classname="org.apache.tools.ant.taskdefs.optional.junit.JUnitTask"
classpathref="runtime-classpath"/>
Then I got this printout (Failing at my taskdef) :
..................

So it can't find junit/framework/TestListener. OK
But this IS on the classpath ??? How this i possible ?
So I removed taskdef and added this :

So the VM can find these classes , but the "junit" task still does'n work
(without or with my try to make new taskdef for it).
SO PLEASE HELP, I AM GOING MAD !

That wont work because of this:
- The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
you cannot redeclare stuff that is already declared; classpath issues:.

This was a brave effort, but it aint going to work.

What was wrong with following this advice :

Re: junit task not working
Posted by Marko van Dooren <Ma...@cs.kuleuven.ac.be>.
I posted this message a while ago, maybe it can help you. It adds the
junit.jar to the classpath and forks the VM. You need the change the path to
junit.jar of course, the org.jutil.jar must be replaced by the jar/classpath
that you are testing.
--------------------------------------------------------------------------------------
I managed to get the junit task to work without removing it from optional.jar
and without putting it in the $ANT_HOME/lib directory. My solution might not
be the most elegant and efficient one, but it works without much trouble.
These 3 targets do the job
<!-- Set ANT_OPTS to "" if is doesn't exist yet
otherwise "${ANT_OPTS}" will be given to the
java VM -->
<target name="antopts" unless="ANT_OPTS">
<property name="ANT_OPTS" value=""/>
</target>
<!-- Set classpath correct, fork VM and call second test stage -->
<target name="test" depends="compile,antopts">
<!-- Add junit.jar and org.jutil.jar to the classpath -->
<property name="testpath"v
alue="${java.class.path}:${lib}/junit.jar:${lib.dist}/org.jutil.jar"/>
<!-- Run ant again with a different target, but fork the VM so we can add
jars to the classpath
See Ant documentation for reasons why it doesn't work when using <junit>
directly. -->
<java classname="org.apache.tools.ant.Main" fork="true"
classpath="${testpath}">
<jvmarg line="-Dant.home=${ant.home} ${ANT_OPTS}"/>
<arg line="test-secondstage"/>
</java>
</target>
<target name="test-secondstage" depends="init">
<!-- perform tests here -->
</target>
I'm not sure whether it is cross-platform or not, I only use linux.
Happy junit testing,

Re: junit task not working
Posted by Diane Holt <ho...@yahoo.com>.
Make sure you have both the optional tasks jar file and junit.jar -- then
read the second Note in the "Description" section on the Junit task page
(in the Ant1.5 manual):
http://jakarta.apache.org/ant/manual/OptionalTasks/junit.html
