Hi, professional developers:

I am writing the a java application using Ant, but stucked on dealing with the Ant Task.
I put the line "import org.apache.tools.ant.BuildException;" in my source code, and run "ant" in the console windows. But got the following error message,

error: Class or interface `org.apache.tools.ant.BuildException' not found in import.

error: Superclass `org.apache.tools.ant.Task' of class `com.gal lery.GalleryRemote.util.PostChangeLog' not found.

error: Class `BuildException' not found

Could someone help me to fix these bugs?
Thanks in advance.

The ant.jar file from Ant must be in your classpath when you build GR with ant.

May I inquire what you're going to use GR for, out of curiosity?

Hello, paour:
Thank you very much for your replying. I am working on a java image processing project and I found Gallery Remote is really great and has some similiar funcionalities. I want to understand how Gallery Remote does the work. So I tried to build this project using Ant, but it cannot found those packages. I am using Linux with JDK1.4.2_5. and I add the three lines to the system profile and type ant in console to build the project but doesn't work.

export ANT_HOME=/usr/local/ant
export JAVA_HOME=/home/wu/Software/j2sdk1.4.2_05
export PATH=${PATH}:${ANT_HOME}/bin

The Ant I am using was installed when I installed the Linux system.
Could you please tell me how to configure the classpath?

I really appreciate you help

Best regards!!!

Thanks for the info.

You should find 'ant.jar' using the locate command to find out where it is in your system.

Thanks for your patientence:

I tried the command "locate ant.jar" in the console windows, and the result is
/usr/share/ant/lib/ant.jar
/usr/share/java/ant.jar
/home/wu/Software/Ant/ant.jar
/home/wu/Software/eclipse/eclipse/plugins/org.eclipse.core.resources_3.0.1/ant_tasks/resources-ant.jar
/home/wu/Software/eclipse/eclipse/plugins/org.eclipse.pde.ui_3.0.1/pdeuiant.jar
/home/wu/Software/eclipse/eclipse/plugins/org.eclipse.pde.build_3.0.1/lib/pdebuild-ant.jar
/home/wu/Software/eclipse/eclipse/plugins/org.apache.ant_1.6.1/lib/ant.jar
/home/wu/Software/eclipse/eclipse/plugins/org.eclipse.pde_3.0.1/ant_tasks/pde-ant.jar

Then I copied the "ant.jar" file from the first folder above to the folder /usr/local/ant
but stilll not working. Is there something wrong with those lines I added to the profile?

Thanks a lot for your replying.

I'm no longer sure I understand what you're trying to do... Are you trying to get an unmodified version of GR to build? Are you modifying it and it no longer builds?

I am trying to get an unmodified version of GR to build to see how the image is processed.
I downloaded the sources form www.sourceforge.net. using CVS. but cannot build it using Ant.
so I post my question here to try to get some help from those who are familiar with Ant.

Thank you very much! :D

OK. The easier solution to that is to simply remove the com/gallery/GalleryRemote/util/PostChangeLog.java file. It's not necessary to run GR (it's used in the process that creates the nightly builds).

That should solve the ant.jar dependancy.

Hi, paour

I really appreciate your help and patientence.
I followed your instruction, and it works. I got another problem that I deleted a few source files by mistake, and I want find the latest version of the source code. I went to www.souceforge.net, but its CVS server is down. Could you please tell me where else I can find the source code. It is really urgent for me.

Thanks a lot.
Best regards!
:D
