Why does a mass-compile ANT script end successfully if one program fails to compile ?

Problem :

When mass-compiling programs using an ANT script, the ANT script ends with BUILD SUCCESSFUL displayed, even when programs fail to compile or link.  How can this be avoided ?

Resolution :

The solution is to use the command :

ant –lib $COBDIR/lib/mfant.jar –f .cobolBuild –DcobolFailOnError -DcobollinkFailOnError

When –DcobolFailOnError  and -DcobollinkFailOnError are used, the ant script will only display BUILD SUCCESSFUL if ALL programs build and link successfully
