Hi All!
I've broken my junit task in Ant...I got an error in a side project where it
couldnt import TestCase, so I copied the junit.jar into the lib dir for that
project, and got "could not create task of type junit" when I ran Ant.
So I realized Ant has its own ant-junit.jar, so I deleted the junit.jar
which I had moved, but now ALL my projects are broken for running tests from
Ant, even though I put things back to the way they were before. I rebooted,
etc. Why would this side project effect all junit tasks?
In my build file I have the junit jar included only for tests.
<path id="compile.classpath">
<pathelement path ="lib/hibernate3.jar"/>
<pathelement path ="lib/commons-lang-1.0.1.jar"/>
<pathelement path ="lib/commons-logging-1.0.4.jar"/>
</path>
<path id="test.classpath"><path refid="compile.classpath"/><pathelement
location="${junit.jar}"/>
<pathelement location="${build.dir}/classes"/>
<pathelement location="${build.dir}/test"/>
</path>
The complie works, but the tests fail:
build.xml:154: 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'. <--- NOT THE PROBLEM
Fix: check your spelling.
- The task needs an external JAR file to execute
and this is not found in the right place in the classpath <--- NOT THE
PROBLEM
Fix: check the documentation for dependencies. Ant's Junit class worked
fine before
Fix: declare the task.
- The task is an Ant optional task and the JAR file and/or libraries <---
NOT THE PROBLEM
implementing the functionality were not found at the time you I didn't
build ant myself
yourself built your installation for Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the 'ant-' JAR corresponding to the
<--- ant-junit.jar is there
task and make sure it contains more than merely a META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the needed
<--- checked the jar, itś good
libraries present in ${ant.homw}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
- The build file was written for a later version of Ant <--- my build
file didn't change
Fix: upgrade to at least the latest release version of Ant from when
junit tagets ran
- The task is not an Ant core or optional task and needs to be declared
using <taskdef> <--- NOT THE PROBLEM
- You are attempting to use a task defined using <--- NOT THE
PROBLEM
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use
Remember that for JAR files to be visible to Ant tasks implemented in
ANT_HOME/lib, the files must be in the same directory or on the
classpath.
Please netither file bug reports on this problem, nor email the
Ant mailing lists, until all of these causes have been explored,
as this is not an Ant bug.
Here is the test target:
<target name="test-batch" depends="test-compile">
<junit printsummary="withOutAndErr" haltonfailure="false"> <-- line
154
<classpath refid="test.classpath"/>
<formatter type="brief" usefile="true"/>
<formatter type="xml"/>
<batchtest todir="${test.data.dir}">
<fileset dir="${test.dir}" includes="**/*Test.class"/>
</batchtest>
</junit>
<junitreport todir="${test.data.dir}">
<fileset dir="${test.data.dir}">
<include name="TEST-*.xml"/>
</fileset>
<report format="frames" todir="${test.reports.dir}"/>
</junitreport>
</target>
in properties.xml
<property name="junit.dir" location="${ant.home}/lib"/>
<property name="junit.subdir" value=""/>
<property name="junit.jar"
location="${junit.dir}/${junit.subdir}/junit.jar"/>
I changed junit.jar to ant-junit.jar:
<property name="junit.jar" location="${junit.dir}/ant-junit.jar"/>
Still got the error.
I have two junit.jar files:
in junit3.8.1 which is used for the JUNIT_HOME variable
and
in apache-ant-1.6.5/lib/ant-junit.jar
could there be a conflict between the junit.jar in the JUNIT_HOME variable
and the ant/lib/ant-junit.jar when running the junit task from ant?
/home/timmy/apache-ant-1.6.5/lib/ant-junit.jar and
/home/timmy/junit3.8.1/lib/junit.jar
I found this post on the mailing lists after googling:
> But I have notified that I have two junit.jars in the above

No, at least not as long as both are the same version.
In the ant-junit.jar manifest I found:
Ant-Version: Apache Ant 1.6.5
MY version : apache-ant-1.6.5
So, as the poster said, shouldn't be a problem. Keep in mind, before this
fiasco, I had the tests running from this side project fine. I still don't
know why all of a sudden the build couldn't find TestCase and made me copy
the junit.jar to the subprojects lib in the first place, consequently
messing up all my projects testing ability!
Keep in mind, I've been using junit tasks on this particular box running
Fedora Core 3 for over a year, with no changes to the jars. The sub project
is a Hibernate learning project. I can't get Hibernate configured correctly
to talk to MySQL, so I made a sub project to test the connection. This
seems like too much info, so I'm sorry for overdoing it.
Thanks for your time
Taemin.
