"Ant-script" mode - Projects/Steplibs search

In "Ant-script" mode, we can't run Unit Test when NSAs and NSNs are in 2 projects, sometimes in the same library name, and in "Steplib" library in another project too.

So, "run.cmd" doesn't work :
[testsuite] Exception: Could not load contents of data area GDACM02. Please check that the source has been downloaded and/or verify that the steplib is correct.
[testsuite] com.softwareag.entirex.importtool.nat.NaturalException: Could not load contents of data area GDACM02. Please check that the source has been downloaded and/or verify that the steplib is correct.

It would be good to have this functionality to run "Ant-script" in Jenkins for example, to automate Unit Test (Natural Unit Test, External Data Test, Sequence Unit Test, etc.)
