Call ant several times with different parameters

Question

Is it possible in Ant to repeatedly call the same target with different parameters?

My command is as follows:

ant unittest -Dproject='proj1' unittest -Dproject='proj2' 

The problem is that unittest runs twice, but only for proj2:

 unittest: [echo] Executing unit test for project proj2 unittest: [echo] Executing unit test for project proj2 

I know that I can run two separate Ant commands, but this will cause additional problems with the unit test report files.

You can add another target to run your unittest target twice with different parameters using the antcall task, for example.

 <project name="test" default="test"> <target name="test"> <antcall target="unittest"> <param name="project" value="proj1"/> </antcall> <antcall target="unittest"> <param name="project" value="proj2"/> </antcall> </target> <target name="unittest"> <echo message="project=${project}"/> </target> </project> 

Output:

 test: unittest: [echo] project=proj1 unittest: [echo] project=proj2 BUILD SUCCESSFUL Total time: 0 seconds 

Alternatively, you can change the unittest target as a macrodef :

 <project name="test" default="test"> <target name="test"> <unittest project="proj1"/> <unittest project="proj2"/> </target> <macrodef name="unittest"> <attribute name="project"/> <sequential> <echo message=" project=@ {project}"/> </sequential> </macrodef> </project>
