Ant Delete task - Deleting a file from a directory while comparing
from another directory
Hi All,
Can someone please let me know, whether the ANT code below is good or- what
it will do.
I have 3 files in backup.dir folder and 3+1 extra file in release.dir
folder. The 1 extra file inside release.dir folder is a new file added to
the release folder (patching) before running the code below.
Now (for unpatching that new file), I want to write a code that should
compare the files between backup.dir and release.dir folders…and it should
pick the new file and say that oh!!! This is the new file and for
un-patching it I have to remove that new file from the release.dir folder
and then I’ll move the file’s from backup.dir folder to release.dir again
(so that the old changes will get placed on runtime release.dir folder
again, see code in Green color, I know that it’s perfect, but I want your
suggestions for removing a file from release.dir if that file/s has/have
been added to release.dir folder recently and considered as new file/s. So
for this, see RED lines below and let me know what it will do, whether it is
a correct code, or how can I achieve my goal).
65 <delete>
66 <fileset dir="${release.dir}">
67 <present present="srconly" targetdir="${backup.dir}"/>
68 <include name="**/*"/>
69 </delete>
71 <move todir="${release.dir}">
72 <fileset dir="${backup.dir}">
73 <include name="**/*"/>
74 </fileset>
75 </move>
Brgds,

RE: Ant Delete task - Deleting a file from a directory while comparing from another directory
Posted by "Sangal, Arun" <Ar...@galileo.com>.
Thanks David for putting light on it. Well, here is my actual >>>> ?
I have to do the following task:
1) I have 5 files to patch at release folder (or you can say runtime
folder).
2) 4 files already exist at runtime with version 1.4
3) The files I'm going to patch is having 4 files (with version 1.5) and
1 new file with
version 1.1. These 5 files are stored inside ${patch.dir} folder.
4) Now, Patching is working file. After the patching gets complete,
script first creates
a backup folder (excluding the new file as it's was not present
before patching).
This folder is stored at ${backup.dir} location. And as I said
patching is working
Fine, I'm seeing version 1.5 for the existing 4 files and the new
file also gets
patched there at release/runtime folder.
***** Till this point everything is working OK ******
5) Now, what if someone tells me to unpatch what I have done????
6) My steps would be:
a) Place the files from backup folder again at runtime (i.e. 4 files
will again
get the same old copy of version 1.4)
b) Remove if there is any new files/folders that have been added
during patch step.
(here in this case, I have to remove only that single newly added
file to the
patch folder having version 1.1 from the release folder). If
this happens,
release folder will become same as it was before we started
patching task.
7) NOW, what code shall I write that will compare backup and patch
folder and if it finds a file in patch folder that is not present in
backup folder (means it's a totally new file meant to be inserted in the
release folder), then it should pick that file/s// folder/s and remove
it from the release folder ??????????????????
The latest code I have written in the patch/unpatch script is as follows
for doing the step 6c =or= 7th.
<delete dir="${release.dir}">
<fileset dir="${patch.dir}">
<present present="srconly" targetdir="${backup.dir}"/>
<include name="**/*"/>
</fileset>
<echo message="New files/folders applied during the patching step
have been removed now from release folder!"/>
<echo
message="----------------------------------------------------------"/>
</delete>
Kindly help or let me know, in case you need more clarification.
Thanks-
Brgds,

Unfortunately, like most mailing lists, this is a text only list.
You'll have to point out the line numbers that you have questions
about, and where in the line. Also remember that not everyone uses
monospaced fonts (stupid Gmail!), so you can't depend upon line
spacing to help point out the error either.
It looks like you ask it to delete files only if the file is found in
the ${release.dir}, but not in the ${backup.dir}. Is this correct?
Then, it moves all the files from ${release.dir} to ${backup.dir}.
My only issue is that if there is a new file, you're not moving it to
backup.dir.
