It isn't clear to me which maven plugin uses that property
(https://gwt-maven-plugin.github.io/gwt-maven-plugin/compile-mojo.html#generateJsInteropExports
shows that the old plugin would support
-Dgwt.compiler.generateJsInteropExports=true,
and I think https://tbroyer.github.io/gwt-maven-plugin/compile-mojo.html
would expect the flag to be listed as each a compiler arg,
codeserver/devmode arg, and passed as part of gwt.args to tests), but if it
is working now, that was the issue.
GWT doesn't default to exporting every non-native jsinterop type and member
as this increases code size - each of these becomes and entrypoint, which
can prevent the compiler from obfuscating some names, rewriting method
signatures or pruning members, and can limit what code can be moved to
split points. So, you must opt-in to this feature, and adding this flag is
part of the requirements for that.
Odds are that you can add that flag to your pom.xml directly in the plugin
configuration, so you need not list it from the command line.
