I'm testing now without this but I believe the codepath is when it hit src/main/resources/logback.xml
Not an easy one:

We do our best to limit build time initialization but with SLF4J that's hard to avoid and here SLF4J build time init trigger logback SaxEventRecorder which performs javax.xml.parsers.FactoryFinder static init at build time.
Trying to intialize javax.xml.parsers.FactoryFinder at build time requires to configure a lot of other classes initialized at build time too so that seems a dead end to me.
Any thoughts @aclement?
It worked for me just by deleting the file (I got further), so I'm not blocked.
Hi,
I stumble upon this issue as well, and want to add some points;
It seems like having the logback file logback-spring.xml will result in below error:

Which is quite odd since the logback file is actually have the correct extensions.
While in my case, when using logback.xml logback file, it will result in build error (I'm using maven btw);

and yes, deleting the logback file causes the issue to disappear.
This temporary limitation is now documented.
When we fix that, let's make sure <springProperty /> is supported as described in #607.
logback.xml support seems more complicated than I thought originally, especially with Janino (a java compiler) involved.
Ran into this one while upgrading to 0.9.x. Did not occur in previous versions.
I am wondering whether Spring Boot should add more documentation (or features) about Logback's Configurator which allows for programmatic configuration instead of XML configuration. Favoring programmatic configuration would probably be a good way to mitigate this issue, but I'm having some problems finding good documentation for extending Spring Boot configuration.
What do you think ?
This should be discussed in: https://github.com/spring-projects/spring-boot/issues/25847
This was a blocker for me. I wanted to convert to native but our projects need the logback-spring.xml and springProperty and also the compiler (for if blocks/statements).
A way forward might be to implement a new configuration file format but with native 'if' support without using janino compiler? Perhaps a more lean method of setting your appenders (that is somewhat compatible with logback on a basic level).
Having the same issues with my project. So far we've been able to copy a standard logback-spring.xml between our projects. This enables our Splunk HTTP Appender. We're using the follwoing code and other springProperty placeholders:
<!-- Import Non-Production Spring Properties & Set Defaults -->
<springProperty name="LOGGING_SPLUNK_URL" source="logging.splunk.url" defaultValue="---"/>
<springProperty name="LOGGING_SPLUNK_TOKEN" source="logging.splunk.token" defaultValue="---"/>
<springProfile name="prod">
<!-- configuration to be enabled when the "prod" profile is active -->
<!-- Import Production Spring Properties & Set Defaults -->
<springProperty name="LOGGING_SPLUNK_URL" source="logging.splunk.url" defaultValue="----"/>
<springProperty name="LOGGING_SPLUNK_TOKEN" source="logging.splunk.token" defaultValue="---"/>
</springProfile>
Also fails for me with version 0.9.2. After seeing Logback is supported, but not configuration with logback.xml
I wondered if configuration via logback.groovy would work. It does not build via ./gradlew bootBuildImage:
Error: Classes that should be initialized at run time got initialized during image building:

quite a lot of org.codehaus.groovy.NAME was unintentionally initialized at build time. To see why

Not advocating for logback.groovy, but I would have used it to workaround this issue. The basic customization via application.properties is not sufficient. I'm forward to https://github.com/spring-projects/spring-boot/issues/25847 , I always thought logback.xml was a weird way to configure logback.
@joeyslalom don't hesitate to add a 👍 to the issue spring-projects/spring-boot#25847. If we show that we would like this feature the spring boot team will be more motivated to do it :)
Hm, now I'm wondering what is the reproducible case :) What I did is I enabled xml support removeXmlSupport = false added type hints to all the different logback's converters, encoders and policies my app is using and now I'm able to run app just fine with my xml config including springProfile using -Dlogging.config=/path/to/my/logback-config.xml. No error during build or runtime.
With janino on CP and janino if condition in xml file (as far as I can tell I've added necessary TypeHints) the generated image just exit without any message with exit code 1.
Hm, Janino creates class at runtime and loads it. That could be the cause.
Hm, now I'm wondering what is the reproducible case
I see now it happens in case logback.xml is embedded in the application.
https://github.com/spring-projects-experimental/spring-native/commit/a9e661b4104a93c02cb8203f4422e082ad22f365 assume this feeds here https://docs.spring.io/spring-native/docs/current/reference/htmlsingle/#_application_failed_to_start_when_running_code_mvn_spring_boot_run_code eventually
See https://docs.spring.io/spring-native/docs/current-SNAPSHOT/reference/htmlsingle/#logback-workaround/
See also my recent update of Logback support documentation with explain how to specify configuration with logback-config.xml at runtime.
I created ch.qos.logback.classic.spi.Configurator file, CustomConfigurator class, and added @InitializationHint annotation as described in the documentation below.
10.2.3. How can I configure programmatically Logback as a logback.xml alternative?
But anyway, when I build, I get the following error,

am I missing something?
Indeed, I can reproduce. Since embedded logback-spring.xml is now a better way to solve this as discussed here, I will just remove this programmatic Logback configuration from the documentation.
This will be supported in Spring Boot 3 RC1 to be released tomorrow via https://github.com/spring-projects/spring-boot/commit/4a76fbf93c03b45917f06c65bbd877ac160a6149 thanks to @wilkinsona.
