Visual COBOL for Eclipse uses an ANT script, .cobolBuild, to build COBOL projects. This script is automatically generated from the .cobolProj project file. It is not possible to configure the IDE so that it uses existing external build scripts (such as makefiles, msbuild, shell scripts or others) for building COBOL applications.
You can still use existing build scripts to build COBOL applications outside of the IDE. You can set your own shell scripts as pre-build and post-build events and they will execute as part of the .cobolBuild ANT script before or after compiling.
