Java task on Linux

Hello,

Trying to use Ant 1.2 with JUnit 3.5 on Linux using the java task.  I
haevn't tried using the junit task because the documentation says this
won't work with JUnit 3.5.  I am trying to get the examples from the
following article to work:

    http://www-106.ibm.com/developerworks/library/j-ant/?dwzone=java

With the sample code for the article at:

    ftp://www6.software.ibm.com/software/developer/library/antsample.zip

The problem seems to be with the "fork" property in the runtests target:

    <target name="runtests" depends="compiletests" if="junit.present">
        <java fork="yes" classname="junit.textui.TestRunner"
            taskname="junit" failonerror="true">
            <arg value="test.com.company.AllJUnitTests"/>
            <classpath>
                <pathelement location="build/lib/${app.name}.jar" />
                <pathelement location="build/testcases" />
                <pathelement path="" />
                <pathelement path="${java.class.path}" />
            </classpath>
        </java>
    </target>

I have tested this with JDK 1.2.2 and JDK 1.3 and it works fine with
fork="no".  When set to fork="yes" (which the sample code uses), I get:

Searching for build.xml ...
Buildfile: /home/greg/antjunit/sample/build.xml

jar:

runtests:

Any help is appreciated.

Re: Java task on Linux

Posted by Diane Holt <ho...@yahoo.com>.
Could it be picking up a weird 'java' from your $PATH... out of curiosity,
what happens if you include the "jvm" attribute, giving it the full-path
to, say, your jdk13 'java'?
