Red Hat Bugzilla – Bug 443656
Make ant-nodeps a dependency of any optional ant task jars
Last modified: 2011-06-19 16:45:33 EDT
Description of problem:
Having fought with ant many times on Fedora, I've finally found out why I
couldn't get the replaceregexp task working even after installing the requisite
ant-apache-regexp rpm. The problem is that ant-nodeps is not installed by
default, and it is the jar the contains the actual taskdefs for all the optional
ant tasks. Fedora should either include this jar as a default, or at least have
all the optional task jars include it as a dependency.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Install Fedora 8
2. yum install ant.i386 ant-apache-regexp.i386 (or ant-apache-oro.i386)
3. Create a build script with a regexpreplace task in it.
4. Run the script to see the failure.
Error message is given saying the taskdef for regexpreplace can't be found.
The build script should run with no issue.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
In Fedora 14, this is still a problem. replaceregexp and regexpmapper are "optional" elements, but are supposed to work in any Java >= 1.4 without any dependencies except the ant core.
When a casual ant user installs ant and tries to run a build.xml that works fine on other platforms, instead they get:
Could not create type regexpmapper due to No supported regular expression matcher found: java.lang.ClassNotFoundException: org.apache.tools.ant.util.regexp.Jdk14RegexpMatcher
They know they are running a Java >= 1.4 and the ant documentation says this should just work. The fact that org.apache.tools.ant.util.regexp.Jdk14RegexpMatcher is in ant-nodeps.jar and that ant-nodeps.jar is provided by the package ant-nodeps is not something the average ant user should need to know.
This could be resolved in one of three ways:
1. Add ant-nodeps as dependency of ant.
2. Bake ant-nodeps into ant.
3. Add some form of stub to instruct the user that in order to get this optional functionality they need to install ant-nodeps.
This has been fixed in SL6, so presumably also in RHEL6:
yum install ant-apache-regexp
ant-apache-regexp x86_64 1.7.1-13.el6 sl 27 k
Installing for dependencies:
ant-nodeps x86_64 1.7.1-13.el6 sl 781 k
Is it really still WONTFIX in Fedora?
