I needed something similar. Both of our requirements requires the age of a
file/directory to be determined. Therefore, the easiest approach I found was
to write my own ANT condition. By writing a condition, you can use it inside
an if statement or whatever else in ANT that supports conditions. Here is
source code. I am sure it can be improved.
import java.io.File;
import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.taskdefs.condition.Condition;
public class FileAgeCondition implements Condition {
protected String _file = null;
protected float _age = -999.25F; //In seconds
protected boolean _olderThan = true;
public boolean eval() throws BuildException
{
if((_file == null) || (_file.length() == 0))
throw new BuildException("file must be set");
if(_age == -999.25F)
throw new BuildException("age must be set");
File file = new File(_file);
if(!file.exists())
return(true);
long now = System.currentTimeMillis();
long fileAge = file.lastModified();
float testAge = _age * 1000.0F;
boolean retVal;
if(_olderThan)
retVal = (now - fileAge) > testAge;
else
retVal = (now - fileAge) < testAge;
return(retVal);
}
public void setFile(String file)
{
_file = file;
}
public void setAge(float age)
{
_age = age;
}
}

Subject: delete directory structures older than X days
Hello,
I googled the mailing list archive and found a matching solution based on
javascript for ant 1.5.
I'm using ant 1.7.1 and tried this to delete NBS-folders (NightlyBuildSystem)
older than a specific amount of time.
<target name="delete.old.stuff"
depends="init"
description="delete all NBS stuff which is older than a specific
amount of time">
<!-- start the timer -->
<stopwatch name="timer.delete.old.stuff"/>
<!-- first calculate the borderline timestamp -->
<tstamp>
<format property="borderline.timestamp" pattern="MM/dd/yyyy HH:mm aa"
offset="${deletion.threadshold}" unit="day"/>
</tstamp>
<echo message="borderline.timestamp=${borderline.timestamp}" />
<!-- now delete all NBS checkouts and stuff older than that boderline
timestamp -->
<echo message="delete ${NBS.dir.prefix}** in ${nbsdir} before
${borderline.timestamp}" />
<delete includeemptydirs="true" verbose="true">
<dirset dir="${nbsdir}" includes="${NBS.dir.prefix}**">
<date datetime="${borderline.timestamp}" when="before"
checkdirs="true"/>
</dirset>
</delete>
<!-- now determine the artifact folder -->
<property name="artifact.dir"
value="${builddir}/CruiseControl/artifacts/${projectname}" />
<echo message="artifact.dir=${artifact.dir}" />
<!-- now delete all artifacts and stuff older than that boderline
timestamp -->
<echo message="delete **/**/* in ${artifact.dir} before
${borderline.timestamp}" />
<delete includeemptydirs="true" verbose="true">
<dirset dir="${artifact.dir}" includes="**/**/*">
<date datetime="${borderline.timestamp}" when="before"
checkdirs="true"/>
</dirset>
</delete>
<!-- print out timer and reset it -->
<stopwatch name="timer.delete.old.stuff" action="total"/>
<echo message="DONE : delete.old.stuff" />
</target>
Unfortunately this construction does not delete anything :-(
The console says this:
delete.old.stuff:
[echo] borderline.timestamp=06/06/2009 17:32 PM
[echo] delete NBS-run** in F:/NightlyBuildSystem before 06/06/2009 17:32 PM
[echo]
artifact.dir=F:\NightlyBuildSystem/CruiseControl/artifacts/Mailminder NBS
[echo] delete **/**/* in
F:\NightlyBuildSystem/CruiseControl/artifacts/Mailminder NBS before 06/06/2009
17:32 PM
[stopwatch] [timer.delete.old.stuff: 0.844 sec]
[echo] DONE : delete.old.stuff
Is there something I'm doing completely wrong?
Is there any possibility to delete such old stuff without using javascript
anyway?
Thanks for your time and your help
Regards
