copying multiple directories (and contents) in one shot - ant

I've been using ant for nearly a decade, but every so often I need to do something beyond my-ordinary experience. This one lacked an obvious answer (and the intuitive approaches led to dead ends)
Problem:
Copy several subdirectories (and their contents) in directory "example" to new directory "myInstance". To clarify, copy some, but not all subdirectories in the source directory.
Source directory:
example/
ignoreThisDirectory/
ignoreThisOneAlso/
lib
etc/
webapps/
Attempt: Dead End
This attempt at first appeared to work. It created the subdirectories lib, etc,webapps. However 'copy' did not copy their contents; i was left with empty subdirectories.
<copy todir="myInstance" >
<dirset dir="example" includes="lib etc webapps"/>
</copy>
Successful But Verbose
In the end, I had to copy each directory individually, which seem verbose and non-DRY:
<copy todir="myInstance/etc">
<fileset dir="example/etc"/>
</copy>
<copy todir="myInstance/lib">
<fileset dir="example/lib" />
</copy>
<copy todir="myInstance/webapps">
<fileset dir="example/webapps" />
</copy>
thanks in advance

You can specify multiple inclusion and exclusion rules in a fileset. If you don't specify an inclusion rule, the default is everything is included, except anything that is excluded at least once by an exclude rule.
Here's an inclusive example:
<property name="src.dir" value="example" />
<property name="dest.dir" value="myInstance" />
<copy todir="${dest.dir}">
<fileset dir="${src.dir}">
<include name="lib/**" />
<include name="etc/**" />
<include name="webapps/**" />
</fileset>
</copy>
Note the ** wildcard that will bring in the full directory tree under each of the three 'leading-edge' sub-directories specified. Alternatively, if you want to specifically exclude a few directories, but copy over all others, you might omit inclusion (and thereby get the default all-inclusive behaviour) and supply a list of exclusions:
<copy todir="${dest.dir}">
<fileset dir="${src.dir}">
<exclude name="ignoreThisDir*/" />
<exclude name="ignoreThisOne*/" />
</fileset>
</copy>
You could further boil the particular example you gave down to one exclusion pattern:
<exclude name="ignore*/" />

Ant concat exclude directory

My application folder structure looks like this...
-js
-libs
-jquery.js
-jquery-ui.js
-app.js
-ui.js
I wish to concatenate the .js files that are in the /js directory but not those in the /js/libs directory. I am using the following code, but it is ignoring the exclude statement:
<concat destfile="${build.dir}/js/foot-${build.major}-${build.minor}.concat.js">
<fileset dir="${build.dir}/js">
<exclude name="**/libs/**" />
</fileset>
</concat>
The <fileset> should specify both include and exclude patterns. In addition, it may be good to specify a destination directory for <concat> separate from the <fileset> input directory.
<target name="concat-test">
<concat destfile="${basedir}/concat.js" fixlastline="yes">
<fileset dir="${basedir}/js">
<include name="**/*.js" />
<exclude name="**/libs/**" />
</fileset>
</concat>
</target>

Ant Copying Empty Directories

I am still very new to ant and, although I know coldfusion, I don't know very much about java conventions, but I know that ant is built using java conventions. That being said I am working on an ant process to copy a project to a temp folder, change some code in the project, and then push the temp directory up to an FTP. I am trying to exclude all of my git, eclipse, and ant files from the copy so that my testing platform doesn't get cluttered. I setup a target to do the copy, but it seems that Ant not only is ignoring my excludes (which I am sure I wrote wrong), but it is only copying top level directories and files. No recursive copy. My current target is:
<target name="moveToTemp" depends="init">
<delete dir="./.ant/temp" />
<mkdir dir="./.ant/temp" />
<copy todir="./.ant/temp">
<fileset dir=".">
<include name="*" />
<exclude name=".*/**" />
<exclude name=".*" />
<exclude name="build.xml" />
<exclude name="settings.xml" />
<exclude name="WEB-INF/**" />
</fileset>
<filterset>
<filter token="set(environment='design')" value="set(environment='testing')" />
</filterset>
</copy>
</target>
I know that I am not doing my excludes right, but I don't know what I am doing wrong with them. I see double asterisks (**) used all the time in Ant but I can't figure out
By default an Ant fileset will (recursively) include all files under the specified directory, equivalent to:
<include name="**/*" />
That's the implicit include. If you supply an include, it overrides the implicit one.
Your include
<include name="*" />
Says 'match any file in the fileset directory', but that excludes traversal of subdirectories, hence your issue. Only files and the top-level directories are being copied.
See Patterns in the Ant docs for directory-based tasks: ** matches any directory tree (zero or more directories).
For your case you should be able to simply remove the 'include', so that the implicit 'include all' applies.
Suggest you also investigate the defaultexcludes task, which lets you set up this sort of thing once for the whole project.
Responding to the title of the question. You can include copy of empty directories as follows. (includeemptydirs attribute)
Example:
<copy includeemptydirs="true" todir="${directory}${file.separator}sentinel_files">
<fileset dir="${basedir}${file.separator}sentinel_files"/>
</copy>
Use the documentation provided in:
https://ant.apache.org/manual/Tasks/copy.html

How can I exclude files from a reference path in Ant?

In a project we have several source paths, so we defined a reference path for them:
<path id="de.his.path.srcpath">
<pathelement path="${de.his.dir.src.qis.java}"/>
<pathelement path="${de.his.dir.src.h1.java}"/>
...
</path>
Using the reference works fine in the <javac> tag:
<src refid="de.his.path.srcpath" />
In the next step, we have to copy non-java files to the classpath folder:
<copy todir="${de.his.dir.bin.classes}" overwrite="true">
<fileset refid="de.his.path.srcpath">
<exclude name="**/*.java" />
</fileset>
</copy>
Unfortunately, this does not work because "refid" and nested elements may not be mixed.
Is there a way I can get a set of all non-java files in my source path without copying the list of source paths into individual filesets?
Here's an option. First, use the pathconvert task to make a pattern suitable for generating a fileset:
<pathconvert pathsep="/**/*,"
refid="de.his.path.srcpath"
property="my_fileset_pattern">
<filtermapper>
<replacestring from="${basedir}/" to="" />
</filtermapper>
</pathconvert>
Next make the fileset from all the files in the paths, except the java sources. Note the trailing wildcard /**/* needed as pathconvert only does the wildcards within the list, not the one needed at the end:
<fileset dir="." id="my_fileset" includes="${my_fileset_pattern}/**/*" >
<exclude name="**/*.java" />
</fileset>
Then your copy task would be:
<copy todir="${de.his.dir.bin.classes}" overwrite="true" >
<fileset refid="my_fileset" />
</copy>
For portability, instead of hard-coding the unix wildcard /**/* you might consider using something like:
<property name="wildcard" value="${file.separator}**${file.separator}*" />

How do I use Ant to copy a folder?

I'm trying to copy a directory using the Ant copy task.
I am a newbie at Ant; my current solution is:
<copy todir="${release_dir}/lib">
<fileset dir="${libpath}" />
</copy>
I'm wondering if there is a better and shorter way to accomplish the same thing?
First of all, those are the examples from Ant documentation:
Copy a directory to another directory
<copy todir="../new/dir">
<fileset dir="src_dir"/>
</copy>
Copy a set of files to a directory
<copy todir="../dest/dir">
<fileset dir="src_dir">
<exclude name="**/*.java"/>
</fileset>
</copy>
<copy todir="../dest/dir">
<fileset dir="src_dir" excludes="**/*.java"/>
</copy>
Copy a set of files to a directory, appending .bak to the file name on the fly
<copy todir="../backup/dir">
<fileset dir="src_dir"/>
<globmapper from="*" to="*.bak"/>
</copy>
Secondly, here is the whole documentation about copy task.
Just because the docs were not very clear to me, and because the time I spent can serve others:
The docs say that this "copies a directory (dir1) to another directory (dest)":
<copy todir="../new/dest">
<fileset dir="src/dir1"/>
</copy>
Actually, this does not mean "copy dir1 inside dest", but rather "copy the contents of dir1 inside dest".
(In general, in Ant, the "root dir" of a filesets -as well at the todir attribute- is not considered as being part of the set itself.)
To place the directory dir1 inside dest one has several alternatives (none totally satisfying to me - and I'd imagined that the new DirSet would help here, but no)
<copy todir="../new/dest/dir1">
<fileset dir="src/dir1"/>
</copy>
or
<copy todir="../new/dest">
<fileset dir="src" includes="dir1/**"/>
</copy>
See also here and here.
From http://ant.apache.org/manual/Tasks/copy.html:
<copy todir="../new/dir">
<fileset dir="src_dir"/>
</copy>
This will do it:
<copy todir="directory/to/copy/to">
<fileset dir="directory/to/copy/from"/>
</copy>
The ant manual is your friend: Ant Manual, in this case: Copy Task

Ant - copy only file not directory

I need to copy all files in a folder except directory in that folder using Ant script.
Im using below script to do that.
<copy todir="targetsir">
<fileset dir="srcdir">
<include name="**/*.*"/>
</fileset>
</copy>
But it copies all files and directory in that folder.
how to restrict/filter directory in that folder?
thanks,
I think there is an easier way.
flatten="true" - Ignore directory structure of source directory, copy all files into a single directory, specified by the todir attribute. The default is false.
Do you mean that srcdir conatins sub-directories, and you you don't want to copy them, you just want to copy the files one level beneath srcdir?
<copy todir="targetsir">
<fileset dir="srcdir">
<include name="*"/>
<type type="file"/>
</fileset>
</copy>
That should work. The "**/*.*" in your question means "every file under every sub directory". Just using "*" will just match the files under srcdir, not subdirectories.
Edited to exclude creation of empty subdirectories.
I do not have enough reputation to comment, so I'm writing new post here. Both solutions to include name="*" or name="*.*" work fine in general, but none of them is exactly what you might expect.
The first creates empty directories that are present in the source directory, since * matches the directory name as well. *.* works mostly because a convention that files have extension and directories not, but if you name your directory my.dir, this wildcard will create an empty directory with this name as well.
To do it properly, you can leverage the <type /> selector that <fileset /> accepts:
<copy todir="targetsir">
<fileset dir="srcdir">
<include name="*"/>
<type type="file"/>
</fileset>
</copy>
Can you try
<copy todir="targetsir">
<fileset dir="srcdir">
<include name="*.*"/>
</fileset>
</copy>
** is used to match a directory structure.
<copy todir="targetsir" includeEmptyDirs="false">
<fileset dir="srcdir">
<include name="*"/>
</fileset>
</copy>
If your folder has many subdirectories and you don't want them to be copied (if you want only files) try this..
<target name="copy">
<copy todir="out" flatten="true">
<fileset dir="tn">
<filename name="**/cit.txt" />
</fileset>
</copy>
</target>
The secret is to use not fileset but dirset instead.
