The following is my code:
<mkdir dir="C:\LabTools"/>
<exec dir="C:\LabTools" executable="${TrueCM_App}\wco.exe" failonerror="true">
<arg line='-R -S"/LabTools/${TrueCM_Tip}/ANT_SASE_RELEASE_${Product_Version}/ANT_SASE_RELEASE_${Product_Version}_-Build" /'/>
first of all,
i would like to create a folder called "LabTools" in C:, then i would like to execute ${TrueCM_App}\wco.exe with the parameters -R -S"/LabTools/${TrueCM_Tip}/ANT_SASE_RELEASE_${Product_Version}/ANT_SASE_RELEASE_${Product_Version}_-Build" /
why is it that <mkdir dir="C:\LabTools"/> is not helping me to make a folder?
<mkdir dir="C:\LabTools"/>
works for me. (are you cleaning it by accident in some other place?)
Check whether you are deleting somewhere in code or it is alredy exist .
Try to run the code again by deleting pre created folder and then check.

In one of our build script, we have following simple copy task added ->
<copy todir="${targetdir}"
file="${sourcedir}/modules/glassfish.jaxb.xjc_1.0.0.0_2-1-12.jar"/>
This copy task started hanging when the glassfish jar name got changed (version upgrade which are not in our control) at the source location. I was expecting it to error out causing the build failure in that case. Actually at first I was not able to figure out at what particular step build was hanging. Then when I added "-debug" to the ant command and I realized its successfully completing a step prior to this copy task and still there was no trace of copy command that is hung. When I updated the new jar name, it worked fine and build was successful which proved that the copy task is hanging because of filename got changed. To make it easy to debug next time, I added an echo statement like below just prior to that copy task ->
<echo message="Copying glassfish jar to ${targetdir}.."/>
But I am still confused as to why it didn't give error with build failure? I am using Apache Ant version 1.7.1. Could this be a bug? How else I can avoid this situation in future with just the copy task (without using * in the jar name)? TIA
That worked for me. Well, didn't work for me. I got the error message. I am using Ant 1.8 and Ant 1.9.2. I didn't try it with Ant 1.7, but I doubt it's a bug.
Try to use the -v parameter in Ant:
$ ant -v target
And be prepared for a longwinded output. This will give you information what's going on with Ant, and may explain why it's freezing. There's a few things you could do: Use a fileset to specify the file.
<copy todir="${targetdir}">
<fileset dir="${sourcedir}/modules">
<include name="glassfish*.jar"/> <!-- Will catch any glassfish.jar -->
</fileset>
</copy>
Of course, if the file doesn't exist, you won't get an error or even a warning. However, a <fail/> before will detect the issue:
<fail message="missing file ${sourcedir}/modules/glassfish.jaxb.xjc_1.0.0.0_2-1-12.jar">
<condition>
<not>
<available
file="${sourcedir}/modules/glassfish.jaxb.xjc_1.0.0.0_2-1-12.jar"
type="file"/>
</not>
</condition>
</fail>
To force the build to quit, an alternative way
<available file="${sourcedir}/modules/glassfish.jaxb.xjc_1.0.0.0_2-1-12.jar"
property="glassfish.jaxb.xjc.jar.present"/>
<fail message="you message" unless="glassfish.jaxb.xjc.jar.present"/>
just a few lines less :)
If you want to dig into it, try this:
write a simple build file, which contains only one target with copy, and put it to the same place of your main build file.
<target name="test-copy">
<!-- here use an old (wrong) file name -->
<copy todir="${targetdir}"
file="${sourcedir}/modules/glassfish.jaxb.xjc_1.0.0.0_2-1-12.jar"/>
</target>
run it, check if it fails or hangs.
If this simple build file works, it's very possible that something else in your main build file is causing the bug.
I have an ant target for creating zip like this -
<zip destfile="${dist}/myzip.zip">
<zipfileset prefix="product/install" includes="docs/resources/**,docs/*.*" excludes="docs/build.bat,docs/*.xml,docs/resources/*.html"/>
</zip>
Now, how do I ensure that empty directories don't get included in this zipfileset.
Eg: docs/resources directory only has html files, all of which I have excluded above. How do I make sure docs/resources folder doesn't get included.
Should I be checking for this manually everytime? or is there an option like includeEmptyDirs="false"?
I think there isn't an option for this in zip task, see documentation.
But what you can do is to make a copy with excludes/includes, and define to exclude the empty directories and then call the zip task on the copied folder:
<copy todir="tmp2" includeEmptyDirs="false">
<fileset dir="tmp1" excludes="**/*.txt"/>
</copy>
<zip>...
Documentation of copy
My ANT build script uses a WebSphere command called createEJBStubs that produces a JAR file with everything plus one new generated class, namely: com/myapp/services/_User_Service_Stub.class.
Since this stub class is only used for running JUnit tests at dev time, I would like it to be in its own JAR file.
How can I tell ANT to copy everything in AAA.JAR that matches, say, _*Stub.class and copy only those files into BBB.JAR (also, maintaining the same directory/package structure)?
Any ideas or pointers would be GREATLY appreciated! Thanks,
Rob
Ok -- answering my own question -- that was surprisingly easy. Sorry I asked.
<unzip src="AAA.JAR" dest="./temp">
<patternset>
<include name="**/_*Stub.class" />
</patternset>
</unzip>
<zip destfile="BBB.JAR" basedir="./temp" />
Thanks ANT.
I'd like to create a temporary directory in ant (version 1.6.5) and assign it to a property.
The command "mktemp -d" would be ideal for this, but I cannot find similar functionality from inside ant
I can't find any official function in the docs apart from the tempfile task which apparently only creates files, not directories.
I'm considering using exec to call tempfile and get the result, however this will make my build.xml dependent on UNIX/linux, which I'd like to avoid.
Background: I'm trying to speed up an existing build process which builds inside networked filesystem. The build already copies all the source to a temporary directory, however this is on the same filesystem. I've tested changing this to /tmp/foo and it gives a worthwhile speed increase: 3mins vs 4mins.
You could combine the tempfile task with the java.io.tmpdir system property to get a file path to use to create a temporary dir:
<project default="test">
<target name="test">
<echo>${java.io.tmpdir}</echo>
<tempfile property="temp.file" destDir="${java.io.tmpdir}" prefix="build"/>
<echo>${temp.file}</echo>
</target>
</project>
Note that the tempfile task does not create the file (unless you ask it to). It just sets a property which you can use to create a file or dir.
This task sets a property to the name of a temporary file. Unlike
java.io.File.createTempFile, this task does not actually create the
temporary file, but it does guarantee that the file did not exist when
the task was executed.
Output in my environment:
test:
[echo] C:\Users\sudocode\AppData\Local\Temp\
[echo] C:\Users\sudocode\AppData\Local\Temp\build1749402932
The answer above only hints at how to create a temporary directory. The point is that merely returns a string. A more complete answer is
<target name="temptest" description="test making tempdir">
<tempfile property="mytempdir" destdir="${java.io.tmpdir}"/>
<tempfile property="mytempfile" destdir="${mytempdir}"/>
<tstamp>
<format property="now" pattern="MMMM dd yyyy"/>
</tstamp>
<copy tofile="${mytempfile}">
<string value="today=${now}"/>
</copy>
<property file="${mytempfile}"/>
<echo message="It it now ${today}"/>
</target>
I have several files with name abc* and i want to delete all those files. is it possible using ant task. For eg. my directory structure is:
c:\
myapp\
abc.xml
abc.txt
abc-1.2.xml
abc-abc.xml
abcdef.xml
pqr.xml
xyz.xml
abc\
so from this, i need to delete all abc* files. So if i use ant it should delete following:
abc.xml
abc.txt
abc-1.2.xml
abc-abc.xml
abcdef.xml
it should leave directory with abc*
Can somebody help me.
Almas
<target name="testingdelete" >
<delete>
<fileset dir="." includes="**/abc*"/>
</delete>
</target>
should work.
It deletes all files with abc* and leaves behind directories named abc. It will delete from all sub-directories as well.
