The junit jar is responsible for junit itself, NOT the ability to run junit from ant. In order to run junit from ant, you also need the ant-junit.jar in the $ANTHOME/lib directory. This should be part of the normal installation of ant so I am not sure why it isn't working for you.
Since you are new to java, you may not know that you can open up any jar with a zip tool, like Winzip or winrar. I do this a lot to inspect the contents of the jar. If you open up ant-junit.jar, you will see that the org.apache.tools.ant.taskdefs.optional.junit.JUnitTask class is inside. --- Shawn Castrianni -----Original Message----- From: Steven Harms [mailto:steven.ha...@gmail.com] Sent: Saturday, June 05, 2010 5:20 PM To: user@ant.apache.org Subject: Trying to get Ant + JUnit working peaceably Hello, I'm attempting to learn Java at present and needed to add some automation around my build and test cycle. Coming from Ruby, I've got a real test-first design discipline. When I attempted to make a <junit> task call, I started getting this error (I can hear eyes rolling...). BUILD FAILED /Users/stharms/java_card/build.xml:38: Problem: failed to create task or type junit Cause: the class org.apache.tools.ant.taskdefs.optional.junit.JUnitTask was not found. This looks like one of Ant's optional components. Action: Check that the appropriate optional JAR exists in -/usr/local/apache-ant-1.8.0/lib -/Users/stharms/.ant/lib -a directory added on the command line with the -lib argument OK, I'm open to trying to step through the directions. Most searches and archives suggested that it was paramount to make sure that the junit library was in $ANTDIR/lib. In this directory I have both: junit-3.8.2.jar : retrieved with ant -f fetch.xml -Ddest=system junit-4.9-SNAPSHOT-20100512-0041.jar : built from github I then thought, OK let's go with the instructions strictly, what's in the lib/optional subdir. Nothing! OK, so I used the fetch.xml task to pull the jars into optional. Re-try, same error. OK, IRC. A kind soul there pointed out that on his debian system this class file was part of optionals.jar that "just worked" as part of using apt-get ant-optionals. Hm, regrettably that answer isn't portable to my platform. So, I'm stuck. Can anyone help me get around this low point. I'm excited to start programming Java, but I've wound up programming Ant most of the day -- not a bad thing, just not the shiny app I had dreamt of :) Thanks in advance, mysterious guru with the answer, Steven --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@ant.apache.org For additional commands, e-mail: user-h...@ant.apache.org ---------------------------------------------------------------------- This e-mail, including any attached files, may contain confidential and privileged information for the sole use of the intended recipient.
