SpringBoot ERROR in ch.qos.logback.core.joran.action.PropertyAction - Could not find resource [/META-INF/build-info.properties]

Greetings Spring gurus,

Goal

I set out to achieve a simple task; include build.version in the log after enabling Spring buildInfo().

Exception from PropertyAction - Could not find resource [/META-INF/build-info.properties].

I seem unable to convince the ch.qos.logback.core.joran.action.PropertyAction.begin(...) that build-info.properties is present on the classpath. Surely I'm missing something obvious, in-order to allow Logback to resolve the reference in logback-spring.xml:

<property resource="/META-INF/build-info.properties"/>

Results in

Symptom discovered in 2.3.7.RELEASE, but also reproducible in 2.3.8.RELEASE and 2.4.2.

Steps to reproduce

I've created a spring-boot application that demonstrates the above symptom here: https://github.com/dlehammer/spring-boot-build-info-logging-issue

git clone git@github.com:dlehammer/spring-boot-build-info-logging-issue.git

cd spring-boot-build-info-logging-issue

./gradlew bootRun

My initial findings

This screenshot illustrates that the build-info.properties are present on the classpath, but seemingly not for all classloaders. SpringBoot ERROR in ch.qos.logback.core.joran.action.PropertyAction - Could not find resource [/META-INF/build-info.properties]

My approach is based on this QA from stack overflow Spring-Boot include build-info as SpringProperty in Logback where the outlined approach works for 2.1 in 2019.

Thanks in advance for your time :)

PS. I appreciate the decision in #6000 as fail-fast ensured I wasn't scratching my head over whether or not the properties was reachable for Logback.

Thanks for the sample. The URL that you have provided for the resource is incorrect. The leading / is not needed and the URL should be META-INF/build-info.properties. With this change in place, the resource is loaded successfully when run using bootRun and java -jar.

Thanks a lot @wilkinsona 👍

I've updated the sample (d8c3309) and can confirm removing the leading / addresses the symptom and the log includes the version as desired.

Ex.
