This topic lists any additional software that you need to be able to use Visual COBOL Build Tools for Windows.
Apache Ant version 1.9.x or later is required if you will be using Visual COBOL Build Tools for Windows to perform build operations using Eclipse project files. You can download Apache Ant from the Apache Ant project's Binary Distributions page.
If you already have Microsoft Build Tools for Visual Studio 2017 installed, you must ensure that it contains the Visual C++ build tools workload (or at least the individual components contained in that workload) before you run this installation.
