I have no CLASSPATH environment variable.  As for the classpath that is used by Ant, it's my assumption that's handled by Ant and/or Maven.  What I can tell you are these things.
  • I'm on Ubuntu Linux, a Debian-based distro, where typically I install things using the package manager rather than by direct download.
  • Therefore, I've both JUnit (3.8.2) and JUnit4 (4.0.0) "installed" courtesy of the apt-get package manager.  But they're not on any CLASSPATH and Ant and Maven were unaware of them.
  • Within the pgjdbc project, I ran `ant' as instructed.  That failed, because the build.xml file has a dependency on JUnit 3.8.2.
  • Helpfully, the Ant build error included instructions for how to satisfy the JUnit dependency (see below).  I found the JUnit 3.8.2 JAR file that apt-get had installed on my system and fed that path into the Maven command.
  • Ran `ant' again.  This time, because the JUnit dependency had been satisfied, it successfully built the JDBC driver.  But because it didn't run any tests, it didn't trigger any run-time error.
  • Ran `ant test' and got the errors that I sent you.
  • Noticed that the SingleCertValidatingFactoryTest class (if nothing else) imports from org.junit, which I understood to be a JUnit4 package (but maybe I'm wrong).
  • I became confused.

The Maven command to install the JUnit jar was:

    mvn install:install-file -DgroupId=junit -DartifactId=junit -Dversion=3.8.2 -Dpackaging=jar -Dfile=/usr/share/java/junit-3.8.2.jar

I assure you that the jar file is a bona fide JUnit 3.8.2 jar file.

Is junit on the classpath ?

Pretty sure I use 3.8.2 

Can you provide me with the errors you are getting ?

Hi,

I'm a little confused as to what version of JUnit I'm supposed to be using in order to build/test the Postgresql JDBC driver.  This page says that "JUnit at least 3.7 is needed."

http://jdbc.postgresql.org/development/development.html

But, there's a big between JUnit 3.8 and earlier and JUnit 4.  The former has components in packages junit.framework while the latter has components in org.junit and so test that directly import on or the other of those packages are sensitive to the version of JUnit you're using.

An example of such a test is SingleCertValidatingFactoryTest.java in pgjdbc/org/postgresql/test/ssl directory (presumably other tests are like this). 

On the other hand, the pgjdbc Ant build.xml file specifies JUnit 3.8.2.:

  <artifact:dependencies pathId="dependency.classpath" useScope="test">
    <dependency groupId="junit" artifactId="junit" version="3.8.2" scope="test"/>
  </artifact:dependencies>

Presumably, this is why running `ant test' in pgjdbc fails for me with compilation errors.  I confess, I'm not an expert with Ant and Maven, so maybe I've done something wrong.  But, exactly waht version of JUnit should I be using?  Thanks!

Best,
David Ventimiglia
