Ant copy files to dir while renaming original files - ant

I have a task that needs to copy over files to a certain location. If the files already exist in the destination, these destination files need to be renamed (appended with .bak). If the destination file doesn't exist, the file should just be put into place.
Currently I have this:
<target name="install-jsps">
<copy todir="target">
<fileset dir="source"/>
<globmapper from="*.jsp" to="*.jsp.bak"/>
</copy>
</target>
This however renames the source files while I want to rename the target files before copying over the source files. I cannot do a rename of the whole target folder because some target files are not in the source fileset.
Preferably I don't want to use an external library like ant-contrib.

You can do it in two copy tasks: one to make the backups, one to copy in the new files from the source. The extra bit you need is the present selector in the fileset used to make the backup. The selector allows you to only back up the files that are about to be superceded, i.e. the ones that are present in the source directory.
<copy todir="dest">
<fileset dir="dest" includes="*.jsp">
<present targetdir="source" />
</fileset>
<globmapper from="*" to="*.bak" />
</copy>
<copy todir="dest">
<fileset dir="source" includes="*.jsp" />
</copy>

Copying only files which have another file as a sibling [based on extension]?

I am trying to use ANT to copy some files of a C++ build into another directory.
The output of the build looks like this:
/Build
/LibA
LibA.lib
LibA.pdb
/LibB
LibB.lib
LibB.pdb
/ProjA
myexe.exe
myexe.pdb
/Foo
foo.exe
foo.pdb
/...
Now, I would like to copy all *.exe files and their *.pdb files to another directory (but not the *.pdb files of the libs).
I tried with:
<copy todir="outdir">
<fileset dir="Build">
<include name="**/*.exe" />
<include name="**/*.pdb" />
</fileset>
</copy>
However, then I will also get the *.pdb files inside the LibA, LibB, ... folders.
Is there any way I can only copy the pdb-files which have an *.exe-file in the same directory as their sibling?
Unfortunately, the folders are not named in any way that would allow using wildcards based on the folder name.
Of course, I could list each file individually, such as:
<include name="ProjA/*.pdb" />
<include name="Foo/*.pdb" />
<!-- ... -->
However, I am thinking that maybe there is an elegant way where I can specify "copy all *.exe files and all *.pdb files which have an *.exe file next to them".
You could use the <present> selector to find the "sibling" files, something like this:
<copy todir="outdir">
<fileset dir="Build" includes="**/*.pdb">
<present targetdir="Build">
<mapper type="glob" from="*.pdb" to="*.exe" />
</present>
</fileset>
<fileset dir="Build" includes="**/*.exe" />
<flattenmapper />
</copy>
This will only copy the .pdb files with matching .exe files.
To keep it simple, use a separate fileset for the exe files.
The flatten mapper is only needed if you want to copy just the files ignoring the directory structure in the source.

No overwrite on Ant UNZIP

I want to unzip a file, but if some file exists, this mustn´t be replaced.
I tried this:
<unzip src="compress.zip" dest="dirTo" overwrite="false">
<patternset>
<include name="dirFrom/**"/>
</patternset>
"dirFrom", is the name from the directory IN the compress file, what I want to extract. I use "overwrite" to false, but it doesn´t work, and it ovewrites.
I have a directory, and this has different subdirectories. I want one of those subdirectories, with it´s files and sub-subdirectories.
I found how to do it.
1st, I extract everything to auxiliar directory.
2nd, I make a loop, to compare file by file, if that file exists.
3rd, If the file doesn´t exists, I copy it.
<unzip src="compressFile.zip" dest="dirAux">
<patternset>
<include name="mySubDir/**"/>
</patternset>
</unzip>
<fileset id="fileset1" dir="dirAux/mySubDir" />
<property name="newContentMySubDir" refid="fileset1"/>
<for param="nameFile" list="${newContentMySubDir}" delimiter=";">
<sequential>
<if>
<not><available file="${finalDir}/mySubDir/#{nameFile}" type="file"/></not>
<then>
<copy tofile="${finalDir}/mySubDir/#{nameFile}" file="dirAux/mySubDir/#{nameFile}"/>
</then>
</if>
</sequential>
</for>
Setting overwrite to false will only prevent to overwrite destination file if it is newer than source file. For more complex filtering, you have to use copy task with a zipfilset as it is explain in ant documentation (see unzip task -- in section Related tasks). For exemple, following code should not extract files from a zip file if they already exist in the destination directory (respecting source directories layout):
<copy todir="${target.dir}">
<zipfileset src="${zip.file}">
<patternset>
<include name="**/*.*"/>
</patternset>
<present targetdir="${target.dir}" present="srconly"/>
</zipfileset>
</copy>

Update destination directory with new files (if modified) using ant

I'm facing a problem with ant "copy". Here is my requirement:
I want to sync 2 dirs(dir1 and dir2) but i want to keep the extra files/dirs present in dir2. My aim is i want to copy dir1 contents(if modified ) to dir2 but want to keep any additional files/dirs present in dir2.
I tried ant's sync task, but it is trying to keep both dirs in sync ie., it is deleting extra contents present in dir2. I don't find any flag to disable this feature:
<sync todir="dir2" failonerror="true" verbose="true">
<fileset dir="dir1" excludes="*.svn" />
</sync>
I tried ant's copy with "modified" selector, but its also doing the same: :(
<copy todir="dir2" failonerror="true">
<fileset dir="dir1" excludes="*.svn" >
<modified/> <!-- Copies only modified files -->
</fileset>
Can any one suggest, how can i achieve my requirement with ant?
By default, the ANT copy task does not overwrite files:
<copy todir="target/dir2" verbose="true" overwrite="false">
<fileset dir="src/dir1"/>
</copy>
The copy task will also detect if the file has changed.
The copy task will not delete files, so I don't understand why your second example (using a modified selector) did not work.

Ant: renaming a group of files subject to a condition

I'm using Ant 1.8.2. Given a directory, how do I add an ".html" extension to all files in the directory and its sub-directories only if those files don't already have an .html extension?
There's an example in the Ant move task docs for renaming .bak files that is similar, here it is adjusted for .html files under a directory called my_dir:
<move todir="my_dir" includeemptydirs="false">
<fileset dir="my_dir">
<exclude name="**/*.html" />
</fileset>
<mapper type="glob" from="*" to="*.html" />
</move>
The fileset excludes files that already have the target extension, the mapper defines the renaming pattern.

Relocate contents of dynamic folder

I have a zip file which has one base folder inside it with other content inside that. I don't always know what that base folder is going to be called until I unzip it.
I'd like to move that base folder, and rename it at the same time, in ant - but can't seem to find out how. I've written code to extract the contents of the zip file to ${local.sdk.dir}/temp/ but from here i can't work out how to rename/move the extracted folder
<move todir="${local.sdk.dir}/${remote.sdk.file.name}">
<fileset dir="${local.sdk.dir}/temp/<WHAT_DO_I_PUT_HERE?>"></fileset>
</move>
also tried
<move todir="${local.sdk.dir}/${remote.sdk.file.name}" includeEmptyDirs="yes" verbose="true">
<fileset dir="${local.sdk.dir}/temp/" >
<include name="**/*" />
</fileset>
</move>
and played about with this, but closest I can get without ant throwing an error is to copy the contents of the temp dir, not the base folder within temp.
You can do all this in one step - copy from the zip file and rename the files changing the dir name as you copy. The copy task accepts a nested resource collection, so you can use a zipfileset to specify the files to copy directly from the zip file.
In order to rename the files as they are copied, you can use a mapper, which the copy task also takes as a nested element. In this case, a cutsdirmapper looks like the tool for the job.
So, if I've understood what you want to do correctly, something like this should work:
<copy todir="${local.sdk.dir}/${remote.sdk.file.name}">
<zipfileset src="${your.zip.file}" />
<cutdirsmapper dirs="1" />
</copy>
cutdirsmapper is only available in Ant 1.8.2 onward, so if you're using an earlier version, you could try a regexpmapper:
<regexpmapper from="[^/]*(.*)" to="\1" />
Similar to this question
<target name="relocate_sdk_folder">
<path id="sdk_folder_name">
<dirset dir="${local.sdk.dir}/temp/">
<include name="*"/>
</dirset>
</path>
<property name="sdk_folder_name" refid="sdk_folder_name" />
<echo message="renaming ${sdk_folder_name} to ${remote.sdk.file.name}" />
<move file="${sdk_folder_name}" tofile="${local.sdk.dir}/${remote.sdk.file.name}" />
</target>
