ANT create fileset from fileset - ant

I know this must be easy but I can't figure out how to do it. I have an existing fileset (from a 3rdparty task) . I'd like to now create a new fileset that includes everything from the first with a few excluded. I should be able to do
<fileset refid"origFileset">
<exclude name="foobar/>
</fileset>
For some reason ant is complaining about this basic operation.

Excluding the setup method of a junit test using ant

Hi I am new to junit and ant.
I want to prevent the JUnit #Before* annotated methods from execution.
Is that possible with Ant's "exclude"?
Are other possibilities to prevent these annotated methods from execution?
thx
No you can't do that with Ant's exclude.
You could use Ant to change the annotation in all files.
http://ant.apache.org/manual/Tasks/replace.html
<replace dir="${tests}" token="#Before" value="#BeforeREMOVED">
<include name="**/*.java"/>
<exclude name="**/*Test*"/>
</replace>
You can adjust/omit the include and exclude tags as necessary to match the files you want.
You can alway change the files back
<replace dir="${tests}" token="#BeforeREMOVED" value="#Before">
<include name="**/*.java"/>
<exclude name="**/*Test*"/>
</replace>
Otherwise you can extend the tests with a new class that overrides the methods. Seems like it might be a lot of work though.

Ant exclude file based on it's content

Is there any way to exclude files from an ant fileset based on the file content?
We do have test servers where code files are mixed up with files that have been generated by a CMS.
Usually, the files are placed in different folders, but there is a risk that real code files are in the middle of generated code.
The only way to differentiate generated files is to open the files and look at it's content. If the file contains a keyword, it should be excluded.
Does anyone know a way to perform this with Ant?
From the answer provided by Preet Sangha, Ishould use a filterchain. However, I'm missing a step here.
Let's say I load a text file of exclusions to be performed:
<loadfile property="exclusions" srcFile="exclusions.txt" />
But I don't know how to integrate it into my current copy task:
<copy todir="${test.dir}">
<fileset dir="${src.dir}">
</fileset>
</copy>
I tried to add the following exclude to the fileset but it does not do anything:
<exclude name="${exclusions}"/>
I'm sure I'm missing a simple step...
Have a look at the not and contains selectors.
The not selector contains an example of pretty much exactly what you're trying to do.
<copy todir="${test.dir}">
<fileset dir="${src.dir}">
<not>
<contains text="your-keyword-here"/>
</not>
</fileset>
</copy>
There's also the containsregexp selector which might be useful if your criteria for exclusion is more complicated.
There's a load more selectors you can use to refine your selection if needed.
I don't know ant but reading the docs....
Can you build a files list using a filterchain, and put this into the excludefiles of a fileset?
or
perhaps create a fileset with a filterchain that uses a filterreader and linecontainsregexp

Why `**/*ant*` exclude pattern doesn't work, but `"**/*ant*/**` works fine?

Let's say I have this in one of my targets:
<path id="files">
<fileset dir="${env.DIRECTORY}" casesensitive="false">
<include name="**/*.html"/>
<exclude name="**/*ant*"/>
</fileset>
</path>
I'd like to group all the html files, except the ones containing the string ant. The way I wrote it above, it does not work. I also tried specifying the exclude like this:
<exclude name="*ant*"/>
Please notice that the fileset has it's case sensitiveness turned off. However, if I write:
<exclude name="**/*ant*/**"/>
This does work. Why don't the first and second versions of exclude work?
First and second case don't match because you are searching for directory name containing ant
Third case matches all files that have a ant element in their path, including ant as a filename.

How to suppress ant jar warnings for duplicates

I don't want ant's jar task to notify me every time it skips a file because the file has already been added. I get reams of this:
[jar] xml/dir1/dir2.dtd already added, skipping
Is there a way to turn this warning off?
This is an older question, but there is one obvious way to exclude the duplicates warning, do not include the duplicate files. You could do this in one of two ways:
Exclude the duplicate files in some fashion, or
Copy the files to a staging area, so that the cp task deals with duplicates, not the jar task.
So, instead of doing:
<jar destfile="${dist}/lib/app.jar">
<fileset dir="a" include="xml/data/*.{xml,dtd}"/>
<fileset dir="b" include="xml/data/*.{xml,dtd}"/>
<fileset dir="c" include="xml/data/*.{xml,dtd}"/>
</jar>
do one of:
<jar destfile="${dist}/lib/app.jar">
<fileset dir="a" include="xml/data/*.{xml,dtd}"/>
<fileset dir="b" include="xml/data/*.xml"/>
<fileset dir="c" include="xml/data/*.xml"/>
</jar>
or
<copy todir="tmpdir">
<fileset dir="a" include="xml/data/*.{xml,dtd}"/>
<fileset dir="b" include="xml/data/*.{xml,dtd}"/>
<fileset dir="c" include="xml/data/*.{xml,dtd}"/>
</copy>
<jar destfile="${dist}/lib/app.jar">
<fileset dir="tmpdir" include="xml/data/*.{xml,dtd}"/>
</jar>
<delete dir="tmpdir"/>
Edit: Base on the comment to this answer, there is a third option, although it is a fair bit more work... You can always get the source to the jar task, and modify it so that it does not print out the warnings. You could keep this as a local modification to your tree, move it to a different package and maintain it yourself, or try to get the patch pushed back upstream.
I don't know of any options on the jar task to suppress these messages, unless you run the whole build with the -quiet switch, in which case you may not see other information you want.
In general if you have lots of duplicate files it is a good thing to be warned about them as a different one may be added to that which you expect. This possibly indicates that a previous target of the build has not done its job as well as it might, though obviously without more details it is impossible to say.
Out of interest why do you have the duplicate files?

Filter a fileset referenced using a refid

I have a fileset (which is returned from the Maven Ant task), and it contains all the jars I need to repack. This fileset is referenced by a refid. I only want to include our own jars, so I would like to filter that. But Ant filesets don't support any further attributes or nested tags if a refid is used.
For example, if the fileset is:
org.foo.1.jar
org.foo.2.jar
log4j.jar
and I want to have a fileset which contains only
org.foo*.jar
How would I do that?
Try using a restrict resource collection, which you can use like a fileset in any task that uses resource collections to select the groups of files to operate on.
For example, for a fileset returned from your Maven task referenced via an id called dependency.fileset you can declare a restrict resource collection like so:
<restrict id="filtered.dependencies">
<fileset refid="dependency.fileset"/>
<rsel:name name="org.foo*.jar"/>
</restrict>
Note you'll have to declare the resource selector namespace as it isn't part of the built-in Ant namespace:
<project xmlns:rsel="antlib:org.apache.tools.ant.types.resources.selectors">
...
</project>
From here you can reference your restrict resource collection in a similar fashion to how you would reference your fileset. For example, to create backups of your filtered set of files:
<copy todir=".">
<restrict refid="filtered.dependencies"/>
<globmapper from="*" to="*.bak"/>
</copy>
Of course you can inline your restrict resource collection if you so desire:
<copy todir=".">
<restrict>
<fileset refid="dependency.fileset"/>
<rsel:name name="org.foo*.jar"/>
</restrict>
<globmapper from="*" to="*.bak"/>
</copy>
Have a look at the Ant documentation on resource collections for further information.
I think you'll need to write an ant task for that. They're pretty easy to write though.
See http://ant.apache.org/manual/develop.html#writingowntask
In your task, you'll need to call getProject() and ask it to give you the fileset, walk through it, and create a new one.
I 'm using Ant with Ivy. With the help of Ivy it is possible to filter dependencies for retrieval, with the following code in ivy.xml:
<dependency name="Project1" rev="latest.integration" transitive="true" conf="modlibs">
<exclude name="${exclusionRegEx}" matcher="regexp" />
</dependency>
<dependency name="Project2" rev="latest.integration" transitive="false" conf="modules"/>
Maybe a quick look at the Ivy source 'll help?
If you are using a sufficiently recent version of Ant and the JDK, for example, Ant 1.7 and JDK 6, then you can use the optional script task to do what you want. (Earlier versions may also work.) The page I linked to, if you scroll down to the text "The goal is to list the filesizes" then you'll see a sample script that creates a Fileset.
This isn't for the faint of heart, and a custom ant task you write yourself will probably be more flexible. But I wanted to point out the option.
