Subject RE: delete directory structures older than X days
Date Tue, 16 Jun 2009 16:30:28 GMT
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
