FileSystemNotFoundException on standalone Spring Boot app about rulebook HOT 10 CLOSED

Thanks for raising this issue. There is a fix in place in the 0.8.1-SNAPSHOT release now that was tested with a Spring Boot packaged Jar. I'm planning on releasing v0.8.1 sometime this weekend.

Here are some examples of how to add the snapshot repo to your project: https://github.com/rulebook-rules/rulebook/wiki/Download-and-Install

After hours of digging and comparing my code to your example Spring Boot application, I finally found the problem!

It is related to the following in build.gradle:
springBoot { executable = true }

This is done as part of Spring Boot convention to enable Spring Boot applications run as Linux in systemd services, as detailed here:
https://docs.spring.io/spring-boot/docs/current/reference/html/deployment-install.html

Once I removed that part, it worked!
This is actually a good news, since we will not use Spring Boot applications run as Linux in systemd, but as part of a Docker image. So it is redundant and can be deleted.

Thanks for all your help! Especially for the Spring Boot example application you posted.
Keep up the good work :-)

From where can I take this fix? It is not in maven repository...

from rulebook.

It's in the sonatype snapshot maven repo: "https://oss.sonatype.org/content/repositories/snapshots"

Succeeded to use sonatype snapshot maven repo.
However, with 0.8.1-SNAPSHOT , when trying to run standalone executable Spring-Boot jar,I get the following exception:

In eclipse IDE it works flawlessly.

Are you using a Spring Boot war deployed on Wildfly? Or a standalone Spring Boot jar w/Undertow? Or, could you attach your source?

I tested this with the Spring Boot example project under rulebook-examples.

But I'll validate the other scenarios listed above and add examples to validate this evening. And of course, if you can provide your specific example, I can ensure it works with that too.

I use standalone Spring Boot jar w/Undertow

from rulebook.

Interesting. That's what I also use here in the helloworld-spring-web app in the Issue90_PojoResults branch (currently deployed as v0.8.1). And I didn't run into that issue; it worked as expected. The project can be seen here: https://github.com/rulebook-rules/rulebook/tree/Issue90_PojoResults/rulebook-examples

Would you mind attaching your example or providing a link so I can see what your specific issue is? Judging by your error, it appears as if RuleBook cannot find the package that contains the POJO rules to scan. However, since you said it is working in your IDE, I have to wonder what's specifically going on there - perhaps a corner case that wasn't accounted for.

from rulebook.

The fix for including POJO rules in a Spring Boot uber jar is in v0.8.1, now pushed to Maven Central.
