Hello !
Hari Krishna Dara a écrit :
Can anyone provide any help in working around or fixing this problem?
It looks like the same bug as
http://issues.apache.org/bugzilla/show_bug.cgi?id=40238 ?
Here is the macro that causes trouble (I stripped the sequence to the
least that causes theis problem, but as I said before, I couldn't copy
this into a standalone build file and reproduce the exception):
<macrodef name="patchifmatches">
<attribute name="source"/>
<!-- See "target" on patchif -->
<attribute name="target"/>
<attribute name="windows" default="true"/>
<attribute name="solaris" default="true"/>
<element name="selection" implicit="true"/>
<sequential>
<fileset id="patchfileset" dir="${branch.path}">
<patternset refid="patch.filelist"/>
<selection/>
</fileset>
</sequential>
</macrodef>
Here is the macro that is part of the same build file and works fine:
<macrodef name="checkIfComponentNeedsPatch">
<attribute name="componentName"/>
<element name="selection" implicit="true"/>
<sequential>
<!-- FIXME: How do I suppress the "override" warning
message this generates -->
<fileset id="patchfileset" dir="${branch.path}">
<patternset refid="patch.filelist"/>
<selection/>
</fileset>
<pathconvert pathsep=" "
property="@{componentName}NeedsPatchTmp"
refid="patchfileset"/>
<condition property="@{componentName}NeedsPatch">
<not>
<equals arg1="[EMAIL PROTECTED]"
arg2=""/>
</not>
</condition>
</sequential>
</macrodef>
How are your macro called ? With what 'selection' ?
How many times each ? In which order ?
What happens when you remove the call to the 'working' one ? (I suspect
it 'fixes' the other :p)
I'm not really surprised by the fact that it works fine when you copy
your macros to a new build file, I had quite a lot of fun trying to
reproduce the bug for the issue :)
Actually what happens is that the same element is used either in several
macros or several times in the same macro. Then as it gets resolved (and
so is not an unknown element anymore) upon first use, it is no longer an
UnknownElement for the remaining calls...
I don't know if this makes sense, but anyway try and apply the patch and
see if it fixes this issue for you ?
MAT.
