Question

I try to run JUNIT test with eclipse and ANT they both are complainen that org.h2.Driver class is not found.

I have h2-1.3.164.jar in my classpath and for proof about it here is classpath from system property java.class.path


c:\trasferer\build;
C:\Program Files (x86)\IBM\IMShared\plugins\org.junit4_4.3.1\junit.jar;
c:\trasferer\lib\ojdbc6.jar;
c:\trasferer\lib\sqljdbc4.jar;
c:\trasferer\lib-test\h2-1.3.164.jar;
c:\trasferer\lib-test\junit-4.8.2.jar;
c:\trasferer\lib-test\log4j-1.2.14.jar;
c:\trasferer\lib-test\TestUtils.jar;
c:\trasferer\lib-test\dbunit-2.4.8.jar;
c:\trasferer\lib-test\slf4j-api-1.5.5.jar;
c:\trasferer\lib-test\slf4j-log4j12-1.5.5.jar;


and I can found class org.h2.Driver from h2-1.3.164.jar when I open it with eclipse.
Ant task for running test and ANT tasks for “build” classpath

<path id="lib.classpath">
    <fileset dir="./lib" includes="*.jar" />
</path>

<path id="test.classpath">
    <fileset dir="lib" includes="*.jar" />
    <fileset dir="lib-test" includes="*.jar" />
    <pathelement location="${dest}" />
    <pathelement location="${test-dest}" />
</path>

<target name="run-test" depends="init-test,compile,compile-test">
    <property name="classPathToUse" refid="test.classpath" />
    <echo>Using classpath: "${classPathToUse}"</echo>
    <junit failureProperty="test.failure" fork="on" forkmode="once" outputtoformatters="true" printsummary="on" showoutput="true">
        <jvmarg value="-Xmx512m" />
        <jvmarg value="-XX:MaxPermSize=128m" />
        <jvmarg value="-Duser.timezone=GMT" />
        <jvmarg value="-Dexternal-properties=${test.properties}" />
        <classpath refid="test.classpath" />
        <formatter type="brief" usefile="false" />
        <formatter type="xml" />
        <batchtest todir="test-results">
            <fileset dir="${test-dest}" includes="**/*Test.class" />
        </batchtest>
    </junit>
    <fail message="test failed" if="test.failure" />
</target>

and here is stacktrace

So could someone tell me what is going on, please?

Answer 1

Could you post the ANT build file section, which runs junit? There are options that switch off use of the CLASSPATH environment variable….

Relying on environment variables makes your build less portable and in my experience is a very inflexible way to manage your java dependencies. I notice you’re already running into the problem of multiple versions of the same library (two copies of junit and log4j).

I would suggest altering your build to declare classpaths at the top of the build.xml file as follows:

<path id="compile.path">
    <fileset dir="c:\trasferer\lib" includes="*.jar"/>
</path>

<path id="test.path">
    <path refid="compile.path"/>
    <fileset dir="c:\trasferer\lib-test" includes="*.jar"/>
</path>

These classpaths can then be used in the various ant tasks, using the classpathref attribute:

<javac srcdir="${src}"
         destdir="${build}"
         classpathref="compile.path"
         debug="on"
         source="1.4"
  />

And junit has a nested classpath capability (useful for adding the compiled classes directory):

<junit printsummary="yes" haltonfailure="yes">
  <classpath>
    <pathelement location="${build.tests}"/>
    <path refid="test.path"/>
  </classpath>

  <formatter type="plain"/>

  <test name="my.test.TestCase" haltonfailure="no" outfile="result">
    <formatter type="xml"/>
  </test>

  <batchtest fork="yes" todir="${reports.tests}">
    <fileset dir="${src.tests}">
      <include name="**/*Test*.java"/>
      <exclude name="**/AllTests.java"/>
    </fileset>
  </batchtest>
</junit>
