Re: [kura-dev] Apache PLC4X Integration?

[Christofer Dutz <christofer.dutz@xxxxxxxxx>]

Hi Maiero,

I managed to get some build working, by not checking out the Kura git 
repo manually, but using the Eclipse installer and after this has 
finished all of it's magic stuff, I then can open the kura project in 
IntelliJ. So IntelliJ seems to be fine with Tycho itself, but not all of 
the scripts and tooling around that. Only the tests seem to be a bit 
problematic this way. Here I'm getting errors, when doing a "mvn 
package", but if I use the "skipTests" at least I can build something.

But as I probably have to learn how to use Kura first, I'll have to 
spare some time doing that first. And as I know a PR will probably not 
be accepted without working tests and a pure maven testsuite will 
probably not work, I'll keep the integration inside the PLC4X project 
repository. This also makes my work a lot easier.

I'll keep on asking questions I run into ;-)

Chris
