Hi...
I'm using exec to perform an svn update for the build. I'm capturing
the output from that and looking for the revision number in it, like
below:
<target name="updatesvn" depends="init">
<exec executable="svn" outputproperty="upout"
resultproperty="upstat">
<arg line="update -r ${svnrev}"/>
<redirector>
<outputfilterchain>
<containsregex
pattern=".*revision:*\s(\d{1,10})\.*$" replace="\1"/>
</outputfilterchain>
</redirector>
</exec>
</target>
My questions:
1) Is there any way to get the equivalent of the
<redirector>/regex into another property? In the cases where svn fails
and you don't get a revision number, I'd like to see what the original
output was. I.e. start with ${upout} and have the result of the regex
be put in ${uprev}? I checked ${upstat} and svn is nice enough to have
a success status even when it fails to execute... Ugh... I'd like to
avoid writing the output to a temp file and using a file-based filter
chain, but I didn't see any way to define that kind of a chain from
property to property.
2) I tried to set a default value for ${upout} to indicate a
failure, but when other tasks try to look at it after this, it only has
the default initializer and not the result of this target. Is the
result of <exec ouputproperty="upout"> target-local if the property has
been defined previously?
3) How does one do conditionals generally? I know <fail> lets you
do conditionals, but where else can you use them?
Thanks
