Hi Sebastian, Chris wrote a very good page on how to compile the library which is a very big software: https://plc4x.apache.org/developers/building.html
On Mac I found no problem to follow the guide and I think on windows
should be fine too.
As extra suggestion on the guide I could add something if you use Gradle
for your software: the compilation build and install all the jars local
in your machine, if you would access this local jar storage via gradle
you have just to add |mavenLocal()| to the list of repositories:
|repositories { mavenCentral() mavenLocal() } |
I’s not not difficult to figure out but I spend a couple of hours
wandering how to do so it’s worth sharing
Regards,
S.
