I'm sure this has either been asked before or is pretty straightforward. But for whatever reason, I cannot seem to make it work. I want to use ant to copy the ${build.classpath} (which contains a colon separated list of jars) to the ${output.dir}/myapp/WEB-INF/lib.
I have this right now and it doesn't seem to work:
<copy toDir="${output.dir}/myapp/WEB-INF/lib">
<fileset file="${build.classpath}" />
</copy>
It treats the whole classpath as one file. How do I get this to work?
The Ant Manual on the copy task contains the answer for your problem. One of the example snippets it provides:
Collect all items from the current CLASSPATH setting into a destination directory, flattening the directory structure.
<copy todir="dest" flatten="true">
<path>
<pathelement path="${java.class.path}"/>
</path>
</copy>
I think somethink like this should work:
<copy todir="${output.dir}/myapp/WEB-INF/lib" verbose="yes" flatten="yes" failonerror="no">
<fileset dir="${build.classpath}">
<include name="*.jar" />
</fileset>
</copy>
or with wildcard in include: <include name="**/*.jar" />
I think you should put all your colon separated jar files to one root folder. If it is not possible then create a separate task that put those jar files into one folder(may be temporary). And assign ${build.classpath} to that folder. Use <fileset dir="${build.classpath}"/> in your copy clause.
I hope, it should help.

I've looked through ant tasks like copy, but can't really seem to find a way. With this kind of file structure:
/Resources/Docs/SpecificDoc/ScalaDocs
I want to rename "ScalaDocs" to "TargetDocs", having an end structure like so:
/Resources/Docs/TargetDocs
Try this.
<copy todir="/Resources/Docs/TargetDocs">
<fileset dir="/Resources/Docs/SpecificDoc/ScalaDocs">
<include name="*" />
</fileset>
</copy>
in our project we use Ant to distribute files. There is hierarchy of files, and they overwrite files from previous level. Like this: default - level1 - level2. Currently it is made the way:
<copy todir="...">
<fileset dir="${root}/default" includes="**/*" excludes="file1" />
<fileset dir="${root}/level1" includes="**/*" />
<fileset dir="${root}/level2" includes="**/*" excludes="file2"/>
</copy>
So we expected that all the folders contain file with the same name, it will be taken from level2 directory.
Not long ago we moved to a new build box with another version of Java and we discovered that the order of filesets is broken.
Is there a way to fix this issue without modifying ant config files? We have a big number of it. If there is no way, how can I got it off cheap? Thank you.
I don't know if the order of filesets is quaranteed, but the order of copy tasks is.
So, following the suggestion of this answer, it might be a good idea to write several copy tasks with overwrite="true":
<copy todir="...">
<fileset dir="${root}/default" includes="**/*" excludes="file1" />
</copy>
<copy todir="...">
<fileset dir="${root}/level1" includes="**/*" overwrite="true" />
</copy>
<copy todir="...">
<fileset dir="${root}/level2" includes="**/*" excludes="file2" overwrite="true" />
</copy>
You can wrap a sort resource collection around your filesets and ensure the order used by copy this way. Sort itself only likes a single resource collection as child element, so you need to wrap the fileset inside a union or resources container.
See http://ant.apache.org/manual/Types/resources.html#sort
Something like
<sort>
<resources>
<fileset dir="${root}/default" includes="**/*" excludes="file1" />
<fileset dir="${root}/level1" includes="**/*" />
<fileset dir="${root}/level2" includes="**/*" excludes="file2"/>
</resources>
<name/>
</sort>
to sort the files by name.
I am using ant to build my application with timestamp. It is running currently. Now i want to get the latest updated folder so that i can copy that to any other folder.
I tried and it is printing me the latest file only but its not copying that file to another folder.
Please help me
<tstamp>
<format property="timestamp" pattern="dd-MMM-yy" locale="en,UK"/>
</tstamp>
<timestampselector property="latest.modified">
<path>
<fileset dir="${Engine.stagging.dir}">
</fileset>
</path>
</timestampselector>
<copy todir="${prjHop.release.dir}" flatten="true" overwrite="true">
<fileset dir="${Engine.stagging.dir}">
<include name="${latest.modified}"/>
</fileset>
</copy>
Also tried this to copy
<copy todir="${prjHop.release.dir}">
<path refid="${latest.modified}"/>
</copy>
<echo message="${latest.modified}" />
this echo is printing current folder and file name. I just want to copy the file inside that folder.
Thanks
The ${latest.modified} contains the absolute path of the file. When you use this path in the include nested element, the copy task will not find the file in the directory specified in ${Engine.stagging.dir} and hence will not copy it.
You can do the copy as follows:
<copy file="${latest.modified}" todir="${prjHop.release.dir}"/>
I am trying to select all jars from the current directory. I am getting confused between:
**/*.jar
*.jar
I assumed *.jar will work the same as **/*.jar. However the following examples are working differently:
<path id="master-classpath-common-lib" >
<fileset dir=".">
<include name="**/*.jar"/>
</fileset>
</path>
<path id="master-classpath-common-lib" >
<fileset dir=".">
<include name="*.jar"/>
</fileset>
</path>
For this case *.jar is not working at all.
Can anyone please give some hint on this.
*.jar means all the .jar files in only within the base directory, the directory specified in <fileset dir="${master.classpath}/lib">. This will not include the files in the subdirectories.
In **/*.jar, ** (used as the directory name) is a special feature, that means all the (nested) subdirectories.
Check out an example with explanation here.
In my build.xml, below works fine :-
<path id="build.classpath">
<fileset dir="lib [myUtils]" includes="*.jar" />
</path>
if lib [myUtils] is of folder type, but don't works, if it's of Linked Folder type.
Also, I found this when googled :-

Is there any trick to achieve this, without copying the dependencies in work folder??
Note that ant should work outside of eclipse as well. So you can't reply in IDE abstractions. You can use symbolic links (if your OS supports them).
If not, you can use the FileSync plugin to synchronize eclipse project folders with external folders. Or you can simply use the <copy> ant task.
I resolved this using copy task:
<copy todir="target/web/linked1">
<fileset dir="../linkdProject/source1" />
</copy>
<copy todir="target/web/linked2">
<fileset dir="../linkedProject/source2" />
</copy>
....
<war destfile="target/webApp.war">
<fileset dir="WebContent" />
<fileset dir="target/web" /> <!-- copy linked resources -->
...
</war>
<delete dir="target"/>
