You can do with a tiny workaround:
define property that will be set once (in your "base" target)
then in the tas check to see if the property is set using the unless statment
<... unless="property.name"...>
</target>
Then you run it only once.
sample code:
<?xml version="1.0"?>
<project name="project" default="default">
<property name="props.A" value="set value"/>
<target name="default" depends="depends1,depends2" description="-->
description">
</target>
<target name="depends1" unless="props.A">
<echo message="props.A is set "/>
</target>
<target name="depends2" unless="props.B">
<echo message="props.B is set "/>
</target>
</project>
i have set the props.a
so it will not execute the corresponding target.

Subject: Avoid repeat of completed tasks
Hello all,
I have a few independent tasks each one creates a jar file and I execute each
one by itself. Most of them depend on the same general jar tasks.
The situation now is that I want to call all of them within an EAR task. I use
<antcall> task to do that.
Every task calls the general task that it depends on, so I have a situation
where a general task that everyone depends on is called a few times. It seems
like a waste of time.
Here is an example of the output (I highlighted the repeated dependant tasks):
buildTechCore:
[echo] TechCore compiled successfully
[echo] TechCore.jar created
buildAppCore:
[echo] Application core resources copied
[javac] Compiling 772 source files to C:\SCMBuild\classes\ApplicationCore
[ejbjar] building ApplicationCore.jar with 796 files
[echo] ApplicationCore.jar created
[echo] Core projects created successfully
buildWFEngine:
[javac] Compiling 78 source files to C:\SCMBuild\classes\Workflow
[ejbjar] building SCMWorkFlowEngine.jar with 93 files
buildFE:
[javac] Compiling 159 source files to C:\SCMBuild\classes\Frontend

[ejbjar] building SCMCommonApplication.jar with 422 files
buildGDSN:
[javac] Compiling 12 source files to C:\SCMBuild\classes\GDSN
[ejbjar] building GDSN.jar with 31 files
buildTechCore:
[echo] TechCore compiled successfully
[echo] TechCore.jar created
buildAppCore:
[echo] Application core resources copied
[javac] Compiling 772 source files to C:\SCMBuild\classes\ApplicationCore
[ejbjar] building ApplicationCore.jar with 796 files
[echo] ApplicationCore.jar created
[echo] Core projects created successfully
buildWFEngine:

[echo] SCMWeb classes compiled successfully
[echo] SCMWeb.war created
buildCommonApp:

[ejbjar] building SCMCommonApplication.jar with 422 files
buildOMS:
[javac] Compiling 224 source files to C:\SCMBuild\classes\OMS
[ejbjar] building OMS.jar with 229 files
buildTechCore:
[echo] TechCore compiled successfully
[echo] TechCore.jar created
buildAppCore:
[echo] Application core resources copied
[javac] Compiling 772 source files to C:\SCMBuild\classes\ApplicationCore
[ejbjar] building ApplicationCore.jar with 796 files
[echo] ApplicationCore.jar created
[echo] Core projects created successfully
buildWFEngine:
[javac] Compiling 78 source files to C:\SCMBuild\classes\Workflow
[ejbjar] building SCMWorkFlowEngine.jar with 93 files
buildFE:
[javac] Compiling 159 source files to C:\SCMBuild\classes\Frontend
[echo] Frontend project compiled successfully
[ejbjar] building SCMFWFrontEnd.jar with 165 files
[echo] SCMFronend.jar created
buildWebModule:
[echo] SCMWeb resources copied
[echo] SCMWeb classes compiled successfully
[echo] SCMWeb.war created
buildCommonApp:
[javac] Compiling 409 source files to C:\SCMBuild\classes\CommonApp
[ejbjar] building SCMCommonApplication.jar with 422 files
and so on....
How can I avoid this situation, so the general tasks will not repeat themselves
but will be executed only once?
Many thanks,
Zeituni
