Description Gustavo Morozowski 2004-08-16 18:32:04 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.3)

Description of problem:
When I run ant -v code in the attached source code the classpath is:


[javac]
'/home/andromeda/clover-1.3.1RC1/tutorial/build:/usr/share/java/ant.jar:/usr/share/java/ant-launcher.jar:/usr/share/java/jaxp_parser_impl.jar:/usr/share/java/xml-commons-apis.jar:/usr/share/java/junit.jar:/usr/share/java/ant/ant-junit.jar:/usr/lib/jvm/java/lib/tools.jar:/home/andromeda/.ant/lib/clover.jar:/home/andromeda/.ant/lib/junit.jar'

When the correct order is (http://ant.apache.org/manual/running.html#lib):

    *  -lib jars in the order specified by the -lib elements on the
command line
    * jars from ${user.home}/.ant/lib
    * jars from ANT_HOME/lib

as in:

'/home/andromeda/clover-1.3.1RC1/tutorial/build:/home/andromeda/.ant/lib/clover.jar:/home/andromeda/.ant/lib/junit.jar:/usr/share/java/ant.jar:/usr/share/java/ant-launcher.jar:/usr/share/java/jaxp_parser_impl.jar:/usr/share/java/xml-commons-apis.jar:/usr/share/java/junit.jar:/usr/share/java/ant/ant-junit.jar:/usr/lib/jvm/java/lib/tools.jar'

As I needed the clover.jar coming before the tools.jar in the
classpath I had to put clover.jar in /usr/share/java and edit the
/etc/ant.conf file.

Version-Release number of selected component (if applicable):
ant-1.6.1-1jpp_3rh

How reproducible:
Always

Steps to Reproduce:
1.untar the source code
2.create a dir $HOME/.ant/lib
3.put clover.jar, junit.jar and clover.license inside $HOME/.ant/lib
4.change to dir where is build.xml
5.execute ant -v code

junit jar file

please put in $HOME/.ant/lib
Comment 3 Gustavo Morozowski 2004-08-16 18:42:36 UTC

ant configuration file 

This is just the workaround I used
Comment 4 Fernando Nasser 2004-08-17 13:14:37 UTC 
This seems to be a documentation error or at least an omission.
The -lib options should/can only be used when invoking ant directly,
i.e., not through the wrapper scripts (which come from Apache itself).

The correct way of doing what you want when using the wrapper scripts
(always the case for RPM installed Ant in any distro, not only Red
Hat) is to set the environment variable OPT_JAR_LIST :

"A user should request optional jars and their dependencies via the
OPT_JAR_LIST variable".

So you would have: 

OPT_JAR_LIST=/home/andromeda/lib/clover.jar

for instance.

Perhaps we should ask Apache to add a note explaining this.  Or better
yet, I believe they should test for a user specified '-lib' and add
the psth specified automatically to what is in OPT_JAR_LIST (what
would you suggest?).  I favor the second.

I want to bring this issue upstream.

Do you have an opinion, or would like to add something to:

"Perhaps we should ask Apache to add a note explaining this.  Or better
yet, I believe they should test for a user specified '-lib' and add
the psth specified automatically to what is in OPT_JAR_LIST (what
would you suggest?).  I favor the second."
