PMML Spring Boot, kogito-examples - "illegal escape character" in PredictionModels

[Andreas Martin]

Hi colleagues,

I tried to compile and run (mvn clean compile spring-boot:run) the PMML and DMN Spring Boot kogito-examples (https://github.com/kiegroup/kogito-examples) on my Windows machine.

While the classes getting generated, a compilation error occurred: "illegal escape character".

The problem is that the generated "PredictionModels" class contains paths, some String, with some wrongly escaped characters of the Windows paths:

What do you think, is that a bug?

Or am I missing a necessary configuration setting?

Cheers,
Andreas

HI Andreas,

from the screenshots, it seems that the generated paths inside the "static" block are correctly-formatted windows paths. Then there is that last line ("/C:/Dev....") that is clearly wrong, but I'm not sure where this comes from. Could you please try again the compilation with full debug ("-X -e") and share log output ?

Thanks

Gabriele

Hi Gabriele
 
Thank you very much for your reply.

Are you sure that the paths (as strings) in the init() block are formatted correctly?

As I said, init() seems to expect strings, where in my case containing backslashes in the path. Should this not be "escaped" - like this: init("C:\\DevProjects\\kogito-examples-stable\\pmml-springboot-example\\src\main\\resources\\test_miningmodel.pmml")

Regards,
Andreas

Hi Andreas, you are right - I had misread.

I've done and  verifying the fix right now, I'll let you know as soon as I open the PR

Best

Hi All, issue still occurring on windows. However, if you spin up WSL2 and build there, you'll have success. hope it helps, Rhett

[Daniele Zonca]

Hi Rhett,

The fix of the problem should be included in Kogito 1.10 that is going to be released few days

Thanks for the WSL2 feedback, it is probably a reasonable workaround for similar issues!
