Problem with migrations location when switched to 0.4.3

[alexeychalov]

After switching to 0.4.3 from 0.4.2 starter does not see migration script directory in packaged boot jar. I.e. when one clean up elastic and then start migration via boot jar app startup. Everything worked fine in 0.4.2 version

[alexeychalov]

Attach logs for both versions

[alexeychalov]

BTW for elastic version 8.8.1 three are some warnings

[xtermi2]

thanks @alexeychalov
This must be the update of org.reflections:reflections from 0.9.12 to 0.10.2: #233
Toughed we had an integration test for this, because we had this issue some years ago
@RiVogel do you have the same issue with 0.4.3?

[RiVogel]

Hi @xtermi2, @alexeychalov: I just tried it out in my project. All my migration scripts are getting collected with the new version 4.3.0, see debugger screenshot and a log screenshot. My configuration in this case is the default one.

After migrating there is a validation mechanism of Hibernate Search which does not fail - so index seems to be completely migrated.

[RiVogel]

@xtermi2: I see that @alexeychalov got a baseline version set and I see some minor changes between 4.2 and 4.3 regarding the baseline validation. Could that be the case?

[alexeychalov]

@RiVogel: actually, baseline version is default one, I didn't set it purposefully. Moreover, my migrations run on application packaged in boot jar startup, if there no problems in your case I guess it may classloader/class path lookup issue. But everything was fine in 0.4.2 version

I'll later will make a test with 0.4.3 version and downgraded reflections version and report the result

[alexeychalov]

Well, actually I cannot use evolution version 0.4.3 with reflections 0.9.12:
Caused by: java.lang.NoClassDefFoundError: org/reflections/scanners/Scanners
at com.senacor.elasticsearch.evolution.core.internal.migration.input.MigrationScriptReaderImpl.readScriptsFromClassPath(MigrationScriptReaderImpl.java:150)

Running just main class is ok, running via gradle bootRun is ok, the problem appears only if I run bootJar via java -jar
So, I think there is a problem scanning bootJar classpath and receiving resources (migrations) from BOOT_INF/classes directory.
I.e. some mechanism changed in reflections library, that leads to error.

[RiVogel]

@alexeychalov: Yes, downgrading did not work since org.reflections also changed the usage of the ResourceScanner somehow.

In the meantime I could reproduce your problem within a minimal reproducer and starting the Spring Boot application with "java -jar". Let's see...

[RiVogel]

I can't believe it. It looks like you ran into this issue: ronmamo/reflections#373

My mimimal reproducer faced the same problem and after downgrading to reflections version 0.10.1 it worked. @xtermi2: Shall we change the dependency to reflections 0.10.1 or just mention it in the documentation?

[xtermi2]

Maybe both. But we also need an unit- or integration test.
I also think about migrating to the spring classpath Scanner. Initially I wanted to avoid the spring dependency in the core lib, but org.reflectiins is also obviously not the best choice.
Maybe https://github.com/classgraph/classgraph is also worth a try, it's actively maintained and has zero dependencies.

[xtermi2]

@RiVogel and/or @alexeychalov can you checkout the branch bugfix/replace_org.reflections_with_classgraph from PR #241 and locally build the 0.5.0-SNAPSHOT version to verify this issue is fixed in your application / reproducer-app?
