According to http://ant.apache.org/manual/running.html#libs, starting from version 1.6, ant is able to add jars from user specific directory, ${user.home}/.ant/lib. I noticed that ant was ignoring that directory all together. I'm not an ant expert but looking at the vanilla ant script found in dist/bin/ant, I can see that they use the org.apache.tools.ant.launch.Launcher as the class to use. However, the gentoo /usr/bin/ant uses org.apache.tools.ant.Main as the class to use. Looking at the ant sources, I think ./src/main/org/apache/tools/ant/launch/Launcher.java is the only place where ant scans the ${user.home}/.ant/lib directory. The obvious fix to try was to replace org.apache.tools.ant.Main with org.apache.tools.ant.launch.Launcher in /usr/bin/ant. I tried that with mixed results. To tell you the whole story I have a clover.jar file in ${user.home}/.ant/lib. Before making the Main to Launcher switch I wasn't even getting the clover <taskdefs> to show up (since the clover.jar never made it into the classpath). After making the switch from Main to Launcher, I could get the task to be recognized but got errors duing javac compilation: Compiler Adapter 'org.apache.tools.ant.taskdefs.CloverCompilerAdapter' can't be found. In any case, I have a pretty good idea that the gentoo ant script is broken, since I can use the vanilla ant script without any problems (its able to see the jars in ${user.home}/.ant/lib). Here's what I do to use the vanilla ant: export ANT_HOME=/home/haroon/src/build/apache-ant-1.6.1/dist and then execute ant as: /home/haroon/src/build/apache-ant-1.6.1/dist/bin/ant I can provide more details upon request.

Upgrading to ant-1.6.1-r1 I noticed that Launcher class is now used to start ant. That's a good sign. Here's build.xml file that I'm using: <project name="money_demo" default="code" basedir="."> <description> moneytest build file </description> <property name="src" location="src"/> <property name="build" location="build"/> <path id="build.classpath"> <pathelement path="${user.home}/.ant/lib/junit.jar"/> <pathelement path="${user.home}/.ant/lib/clover.jar"/> <pathelement path="${build}"/> </path> <!-- Creates Destination directory and compiles files in source directory--> <target name="code" > <mkdir dir="${build}"/> <javac srcdir="${src}" destdir="${build}"/> </target> <!-- runs the tests --> <target name="test"> <java classname="MoneyTest" fork="yes"> <classpath refid="build.classpath"/> </java> </target> <!-- clover --> <target name="with.clover"> <taskdef resource="clovertasks"/> <clover-setup initString="demo_coverage.db"/> </target> <!-- Delete the ${build} directory--> <target name="clean"> <delete dir="${build}"/> </target> </project> Running: ant with.clover code gives me: Buildfile: build.xml with.clover: code: [mkdir] Created dir: /home/haroon/src/build/clover-1.2.4_02/tutorial/build [javac] Compiling 4 source files to /home/haroon/src/build/clover-1.2.4_02/tutorial/build BUILD FAILED /home/haroon/src/build/clover-1.2.4_02/tutorial/build.xml:17: Compiler Adapter 'org.apache.tools.ant.taskdefs.CloverCompilerAdapter' can't be found.

Here's an even simpler test case: <project name="clover.available" default="main" basedir="."> <available property="clover.available" classname="org.apache.tools.ant.taskdefs.CloverCompilerAdapter"/> <target name="main" depends="debug"> </target> <target name="debug" if="clover.available"> <echo message="CloverCompilerAdapter was found"/> </target> </project> Works with vanilla ant script (after setting ANT_HOME as explained in comment 3 and description) and doesn't work with gentoo ant script.
This just keeps getting wierder and wierder. The test case described in comment 4, works if I use the following command line: /opt/sun-jdk-1.4.2.04/bin/java \ -classpath /usr/share/ant/lib/ant-launcher.jar \ -Dant.home=/usr/share/ant \ org.apache.tools.ant.launch.Launcher \ -lib /opt/sun-jdk-1.4.2.04/jre/lib/rt.jar:.:. Obviously the above line is a stripped down version of what is the actual command run by /usr/bin/ant, which incidentally is (introduced new lines for formatting classpath): /opt/sun-jdk-1.4.2.04/bin/java \ -classpath \ /usr/share/ant/lib/ant-launcher.jar: /opt/sun-jdk-1.4.2.04/jre/lib/rt.jar:.:.: /opt/sun-jdk-1.4.2.04/jre/lib/rt.jar:.:.: /usr/share/ant/lib/ant.jar: /usr/share/ant/lib/ant-launcher.jar: /usr/share/ant-optional/lib/ant-antlr.jar: /usr/share/ant-optional/lib/ant-jakarta-bcel.jar: /usr/share/ant-optional/lib/ant-junit.jar: /usr/share/ant-optional/lib/ant-vaj.jar: /usr/share/ant-optional/lib/ant-apache-bsf.jar: /usr/share/ant-optional/lib/ant-jakarta-log4j.jar: /usr/share/ant-optional/lib/ant-weblogic.jar: /usr/share/ant-optional/lib/ant-apache-resolver.jar: /usr/share/ant-optional/lib/ant-jakarta-oro.jar: /usr/share/ant-optional/lib/ant-netrexx.jar: /usr/share/ant-optional/lib/ant-xalan1.jar: /usr/share/ant-optional/lib/ant-nodeps.jar: /usr/share/ant-optional/lib/ant-jakarta-regexp.jar: /usr/share/ant-optional/lib/ant-xalan2.jar: /usr/share/ant-optional/lib/ant-commons-logging.jar: /usr/share/ant-optional/lib/ant-javamail.jar: /usr/share/ant-optional/lib/ant-starteam.jar: /usr/share/ant-optional/lib/ant-xslp.jar: /usr/share/ant-optional/lib/ant-commons-net.jar: /usr/share/ant-optional/lib/ant-jdepend.jar: /usr/share/ant-optional/lib/ant-stylebook.jar: /usr/share/ant-optional/lib/ant-icontract.jar: /usr/share/ant-optional/lib/ant-jmf.jar: /usr/share/ant-optional/lib/ant-swing.jar: /usr/share/ant-optional/lib/ant-jai.jar: /usr/share/ant-optional/lib/ant-jsch.jar: /usr/share/ant-optional/lib/ant-trax.jar: /usr/share/log4j/lib/log4j-1.2.8.jar: /usr/share/xerces/lib/xercesImpl.jar: /usr/share/xerces/lib/xercesSamples.jar: /usr/share/xerces/lib/xml-apis.jar: /usr/share/xerces/lib/xmlParserAPIs.jar: /usr/share/xalan/lib/xalan.jar: /usr/share/junit/lib/junit.jar: /usr/share/antlr/lib/antlr.debug.jar: /usr/share/antlr/lib/antlr.jar: /usr/share/antlr/lib/antlrall.jar: /usr/share/bcel/lib/bcel.jar: /usr/share/regexp/lib/regexp-1.3.jar: /usr/share/bsh/lib/bsh-2.0b1.jar: /usr/share/commons-beanutils/lib/commons-beanutils.jar: /usr/share/commons-logging/lib/commons-logging-api.jar: /usr/share/commons-logging/lib/commons-logging.jar: /usr/share/commons-logging/lib/commons-logging-api.jar: /usr/share/commons-logging/lib/commons-logging.jar: /usr/share/commons-net/lib/commons-net-1.0.1-dev.jar: /usr/share/oro/lib/oro.jar: /usr/share/jdepend/lib/jdepend.jar: /usr/share/jsch/lib/jsch.jar: /usr/share/regexp/lib/regexp-1.3.jar: /usr/share/rhino/lib/js.jar: /usr/share/jython/lib/jython.jar: /opt/sun-jdk-1.4.2.04/lib/tools.jar \ -Dant.home=/usr/share/ant \ org.apache.tools.ant.launch.Launcher \ -lib /opt/sun-jdk-1.4.2.04/jre/lib/rt.jar:.:.: /opt/sun-jdk-1.4.2.04/jre/lib/rt.jar:.:. To reiterate, the long version above DOES NOT work and the stripped down version DOES work.
Created attachment 29589 [details, diff] remove extra entries from LOCALCLASSAPTH in ant launcher script After making this change (see unified diff), my problem is fixed. I have the following questions though: 1) Did I break anything by making this fix? 2) Why was the loonnnnngggg LOCALCLASSPATH necessary given that the Launcher class sort of does the same thing? Cheers and thanks in advance for your attention.
could you please test if ant-1.6.2-r1 fixes this? if it doesn't please reopon the bug
I am running ant-1.6.2-r2 and I can confirm that this is fixed.
verified and closed.
This problem has reappeared. $> epm -q ant-core ant-tasks ant ant-core-1.6.2 ant-tasks-1.6.2-r5 ant-1.6.2-r6 I have clover.jar inside my ~/.ant/lib directory. I expect ant to see this jar file. A simple build.xml file to demonstrate the problem: <project name="clover.available" default="main" basedir="."> <available property="clover.available" classname="org.apache.tools.ant.taskdefs.CloverCompilerAdapter"/> <target name="main" depends="debug"> </target> <target name="debug" if="clover.available"> <echo message="CloverCompilerAdapter was found"/> </target> </project> If ant was successfully able to see clover.jar (from inside ~/.ant/lib) you will see a message "CloverCompilerAdapter was found". Using the ant supplied with gentoo, ant does NOT see the jars inside the lib file. Buildfile: build.xml debug: main: BUILD SUCCESSFUL Total time: 0 seconds To demonstrate that "vanilla ant" (built from source) does not exhibit this behavior, simply build ant from scratch, e.g.: cd ~/src/build tar xjvf /usr/portage/distfiles/apache-ant-1.6.2-src.tar.bz2 cd apache-ant-1.6.2/ ./build.sh After a successful build, you can use the "vanilla ant" by modifying your ANT_HOME variable to: export ANT_HOME=/home/haroon/src/build/apache-ant-1.6.2/dist Rerun the above build.xml again: $ANT_HOME/bin/ant and you will see as output: Buildfile: build.xml debug: [echo] CloverCompilerAdapter was found main: BUILD SUCCESSFUL Total time: 0 seconds If downloading clover.jar is a problem, I can try and come up with a minimalist jar file and a corresponding build.xml file which demonstrates the problem.
Created attachment 46243 [details] minimalist jar file to be put inside ~/.ant/lib
Created attachment 46244 [details] minimalist build.xml file to reproduce the bug
Commenting out line 105 in /usr/bin/ant let's me see jars inside ~/.ant/lib/. FYI, line 105 is where LOCALCLASSPATH has stuff added to it for ant-core, ant-tasks, log4j, xerces-2, etc.... So, now that we know that line 105 is the culprit, how do we go about not breaking the ant default behavior and also integrating all these extra packages?
can anyone verify that just removing 'ant-core,ant-tasks' from the LOCALCLASSPATH= java-config -p line, makes things work?
(In reply to comment #14) > can anyone verify that just removing 'ant-core,ant-tasks' from the > LOCALCLASSPATH= java-config -p > line, makes things work? Yes, taking out ant-core,ant-tasks from the LOCALCLASSPATH= java-config --classpath line works for me. For anyone else following the thread, the attachments found in comment 11, comment 12 can be used to reproduce this bug. The rest of the discussion (in previous comments) is detailed because I was trying to diagnose the problem, until I was able to shrink it down to the minimalist attachments found in comment 11 and comment 12.
Fixed with ant-core-1.6.5
