Steps to Reproduce:

1. I tried on Build tool version 1.2.18 and this bug doesn't exist. But on the latest versions, when you try to build an MTA on windows with a custom command, it throws an error: "Error on windows: cannot run executable found relative to current directory "
2. Should be reproducible on any project with a custom command.
3. Sample below:

`_schema-version: "3.1"
ID: com.sap.bnac.lco.backsync

version: "0.1.0"

modules:

• name: lco-backsync
  type: java
  path: lco-backsync
  build-parameters:
  builder: custom
  build-result: build/**/*.jar
