Re: How do exec:java on a mainclass that calls System.exit() without terminating the maven build?

[Thorsten Heit]

Hi Steinar,

Here is a repro case as simple as I could make it:
  https://github.com/steinarb/convert-xsd-to-rnc

Clone and run with "mvn install"

The maven build ends (for me) as abruptly as the above gist after the
second <execution> in the exec-maven-plugin config.

The <execution> of trang is run to completion (which I can see since
target/dbchangelog-4.31.rnc have been created), but maven stops and
there is no error message as would have been expected for a non 0 return
value of Driver.doMain().

My platform:
  debian 12.10 "bookworm", amd64
  openjdk java 20.0.4
  maven 3.8.7

convert-xsd-to-rnc % mvn clean install

Out of curiosity I cloned your project, executed "mvn clean install", but couldn't reproduce the error you've seen...
