Ant Task get last modified file time - ant

I have an ant task to concatenate javascript files in a directory and output to concat.js What I want to do is first check if any files have a later modified time than that of concact.js before proceeding.
Here is the existing task:
<target name="minijs" depends="lintjs">
<echo>Concatinating ${plugins.dir} to ${plugins.concat}</echo>
<concat destfile="${plugins.concat}">
<fileset dir="${plugins.dir}">
<exclude name="**/vendor/**" />
<exclude name="*beconcat*" />
<include name="**/*.js" />
</fileset>
</concat>

This is what the uptodate task has been created for
<uptodate property="isUpToDate"
targetfile="${plugins.concat}">
<srcfiles dir="${plugins.dir}">
<exclude name="**/vendor/**" />
<exclude name="*beconcat*" />
<include name="**/*.js" />
</srcfiles>
will set the property isUpToDate if none of the files is newer than the target file - and not set the property at all if one of the files is. You can then use unless to conditionally rebuild the file.

How to to control the order of merge in Ant file

I have this code which takes all the files in the folder collection and merges them with the covers.js file. The problem is there are 2 files inside of collections that need to be merged below covers.
But possibly I may want to control the order of how the files are being merged from the collection
folder. IS there a dependency attribute I can use.
<target name="merge box">
<echo>${box.file}</echo>
<concat destfile="${box.file}" fixlastline="yes" append="no">
<fileset dir="${js.src.dir}/components/covers/" includes="**/*.js"/>
<fileset dir="${js.src.dir}/collection/" includes="**/*.js" excludes="base.js"/>
</concat>
</target>
Update
I also tried this but still doesn't work.
<fileset dir="${js.src.dir}/collection" >
<includesfile name="Templates.js" />
<includesfile name="popup.js" />
<includesfile name="popup-extend.js" />
</fileset>
Latest Update
Tried this and it works but it doesn't hold the order of the include files.
<target name="merge box">
<echo>${box.file}</echo>
<concat destfile="${box.file}" fixlastline="yes" append="no">
<fileset dir="${js.src.dir}/components/covers/" includes="**/*.js"/>
<fileset dir="${js.src.dir}/collection" >
<include name="Templates.js" />
<include name="popup.js" />
<include name="popup-extend.js" />
</fileset>
</concat>
</target>
popup-extend is meant to be merged below the popup code but its not doing that matter what order I put them in it will always put it in this order.
Templates
popup
popup-extend
The order I'm trying to get it in is
Templates
popup-extend
popup
Try this:
<target name="merge box">
<echo>${box.file}</echo>
<concat destfile="${box.file}" fixlastline="yes" append="no">
<fileset dir="${js.src.dir}/components/covers/" includes="**/*.js"/>
<fileset file="${js.src.dir}/collection/Templates.js" />
<fileset file="${js.src.dir}/collection/popup.js" />
<fileset file="${js.src.dir}/collection/popup-extend.js" />
</concat>
</target>

Ant BND task does not produce bundle containing any items

I'm having trouble producing a bundle after converting a maven project to an ant project. The bnd ant task creates test.jar but the file only includes a META-INF. The eclipse project is named testproj. What am I missing? Also, does anyone know of a place with more bnd ant task examples? The bnd site itself is a little lacking in this regard, especially with how to build the classpath values.
<project name="testproj" basedir="." default="build">
<patternset id="project.deploy.jars">
<include name="slf4j-api-1.6.1.jar" />
<include name="logback-core-0.9.28.jar" />

test.bnd:

Service-Component:com.test.*
1) Did you look at the ant support included in bndtools? Neil and I go out of our way to make bndtools run in offline mode.
2) The build.xml looks not proper ant syntax? Can you make a small example and post the proper files?
3) bnd should never generate a jar without a MANIFEST.MF file. Does the run have an error?
If you can't solve the problem feel free to send me a zip file with the setup and I'll check what's going on (and report here).
Following help from the group at Google Groups bndtools (which is a group for for both bndtools and bnd), the issue is apparently that the .bnd file does not contain the Private-Package header. This is used to specify the implementation package so make it a base package for all the classes you want brought in.
After I added it, all the classes showed up and the component xml appeared again.
Thanks for your help everyone!

How to preserve file order in Ant concat?

How to preserve file order in Ant concat?
Simple concat with fileset & includesfile produces rather "random" order, as order is not guaranteed:
<concat destfile="C:/targetdir/concatenated.file">
<fileset dir="C:/sourcedir/">
<includesfile name="C:/targetdir/includes.file" />
</fileset>
</concat>
What I need is concatenation in specific order that the files are listed in the includes file.
So far I've found resourcelist, which should preserve order, but I can't seem to be able to produce any concatenated file with it. :/
<concat destfile="C:/targetdir/concatenated.file">
<resourcelist>
<file file="C:/targetdir/includes.file"/>
<filterchain>
<striplinecomments>
<comment value="#"/>
</striplinecomments>
<prefixlines prefix="C:/sourcedir/"/>
</filterchain>
</resourcelist>
</concat>
Plus, the resourcelist can't seem to handle rows like
LibraryX/A/Stuff/Morestuff/*
Instead the row just produces a ".../Morestuff/* does not exist." -error
Includes file has list of relative paths:
LibraryX/A/Stuff/FileA.txt
LibraryX/A/Stuff/FileB.txt
LibraryX/A/Stuff/FileC.txt
LibraryX/A/Stuff/FileY.txt
I was able to get a filelist working pretty easily:
<concat destfile="C:/targetdir/concatenated.file">
<filelist dir="C:/sourcedir/">
<file name="i.txt" />
<file name="n.txt" />
<file name="o.txt" />
<file name="r.txt" />
<file name="d.txt" />
<file name="e.txt" />
<file name="r.txt" />
</filelist>
</concat>
Hope that helps!
If you are using Ant 1.7+, you can use the sort command
<concat destfile="C:/targetdir/concatenated.file">
<sort>
<fileset dir="C:/sourcedir/">
<include name="C:/targetdir/*.file" />
</fileset>
</sort>
</concat>
You can find the documentation of sort here
[On Ant 1.8.2+] You can also pass the fileset via a sort, and sort on filename, like below:
<concat destfile="./${dir.publish}/${dir.js}/b.main-${build.number}.debug.js">
<sort xmlns:rcmp="antlib:org.apache.tools.ant.types.resources.comparators">
<fileset dir="./${dir.publish}/">
<include name="**/${dir.js.main}/**/*.js"/>
<exclude name="**/${dir.js.main}/**/*.min.js"/>
</fileset>
<rcmp:name />
</sort>
</concat>
Couple of things to watch out for:
Directories are sorted before files
Capitals come before lowercase
UPDATE: Another alternative if you need to manually specify order:
<!-- create a ordered list of all the build files so that CIAPI & CIAPI.widget are built first
(can't find a smarter way to do this, since ant filesets are unordered) -->
<fileset id="a" dir="."><include name="CIAPI/build.project.xml"/></fileset>
<fileset id="b" dir="."><include name="CIAPI.widget/build.project.xml"/></fileset>
<fileset id="c" dir=".">
<include name="**/build.project.xml"/>
<exclude name="CIAPI/build.project.xml" />
<exclude name="CIAPI.widget/build.project.xml" />
</fileset>
<union id="all_build_files">
<fileset refid="a"/>
<fileset refid="b"/>
<fileset refid="c"/>
</union>
Ugly, but, erm, this is ant?
try this, put in alphabetical order
<project name="concatPath" default="full">
<target name="full">
<fileset id="fs" dir="./files" />
<pathconvert refid="fs" property="concatList" pathsep=";" targetos="unix"/>
<echo>${concatList}</echo>
</target>
</project>
this can be used with hierarchical structure of directories, and the order will be the exposed by David.
Remember that XML is not order-dependent, by definition.
To concatenate files in a sorted order, consider using <replace> instead.
Create an order file that defines the order. Then, in your build file:
Copy the order file to the destination file with <copy>
Concatenate your files together into a temporary file with <concat>
Load the files into properties with <loadfile>
Insert the text from those files into the destination file with <replace>
Example order file order_file.txt:
FILE_A_HERE
CONCAT_FILES_HERE
Example ant build file build.xml:
<copy file="order_file.txt" tofile="destination.txt" overwrite="yes">
<concat destfile="tempfile.txt">
<fileset dir="includes/">
<include name="*.txt">
<exclude name="fileA.txt">
</fileset>
</concat>
<loadfile property="fileA" srcFile="includes/fileA.txt" />
<loadfile property="concatFile" srcFile="tempfile.txt" />
<replace file="destination.txt" token="FILE_A_HERE" value="fileA" />
<replace file="destination.txt" token="CONCAT_FILES_HERE" value="concatFile" />

Ant: How to select the latest modified file from a directory?

Assume I have a directory which contains several files with the same name prefix and a timestamp, e.g.
my-directory:
- file-0749
- file-1253
- file-2304
How can I tell ANT to select the latest modified file from my directory (in this case this would be file-2304)?
You can do that with the TimestampSelector task from ant-contrib.
<timestampselector property="latest.modified">
<path>
<fileset dir="${my-directory.dir}">
<include name="file-*" />
</fileset>
</path>
</timestampselector>
<echo message="${latest.modified}" />
Found a way without an additional library:
<copy todir="${tmp.last.modified.dir}">
<last id="last.modified">
<sort>
<date />
<fileset dir="${my.dir}" />
</sort>
</last>
</copy>
<echo message="last modified file in ${my.dir}: ${ant.refid:last.modified}" />
You can work directly with ant.refid:last.modified like the echo task does. Don't forget to delete tmp.last.modified.dir.

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}*" />
