Building Master Branch

Hi All,

I am wanting to build the Cayenne master branch to explore adding support
for Postgres JSON, JSONB data types.  I am getting the following build
error resolving the cayenne-maven-plugin when building on Windows or Linux
/ WSL.

Does anyone have suggestions for how to resolve this?

Thanks for your help.

regards Malcolm
