Flyway: Flyway can't find migrations during testing after upgrading from Java 8 to 10

[pupeno]

Which version and edition of Flyway are you using?

5.1.3

If this is not the latest version, can you reproduce the issue with the latest one as well?

(Many bugs are fixed in newer releases and upgrading will often resolve the issue)

This is the latest as of right now.

Which client are you using? (Command-line, Java API, Maven plugin, Gradle plugin)

I'm using the Spring Boot integration.

Which database are you using (type & version)?

PostgreSQL 9.6.2, compiled by Visual C++ build 1800, 64-bit

Which operating system are you using?

Windows 10

What did you do?

(Please include the content causing the issue, any relevant configuration settings, the SQL statement that failed (if relevant) and the command you ran.)

I have a Spring Boot project that I just upgraded from Java 8 to 10. When I added a module-info.java, Flyway stopped being able to find the migrations during testing when running mvn package. It still works when running the application with mvn spring-boot:run or when either running the application or the tests from IntelliJ (probably not very relevant).

I wonder if it's relevant to this other issue I experience with resources:

https://stackoverflow.com/questions/49702287/getresourceasstream-returning-null-in-java-10

I'm not sure because that issue is independent of whether the application is in a module or not, whether this bug clearly happens when adding the application to a module.

What did you expect to see?

Migrations run and tests executed.

What did you see instead?

I tried opening the module to flyway:

opens tech.flexpoint.dashmanserver to org.flywaydb.core;

and that made no difference. I also tried:

opens tech.flexpoint.dashmanserver.db.migration to org.flywaydb.core;

and that changed the error to:

I'm having trouble debugging the issue because I cannot reproduce it on IntelliJ, it only happens when running from the command line.

[axelfontaine]

This is an issue with your setup and not Flyway itself, as Flyway works fine on the module path with Java 9 and newer. StackOverflow may be a better place to ask your question.

[malikoski]

The classloader found the directories (db/migration) but not resources files:
method LineReader loadAsString() - ClassPathResource.java
Line 89: InputStream inputStream = classLoader.getResourceAsStream(location);

I hat put directory/resources ("db/migration") into src/main/resources/META-INF" to work in Java 10.
Very strange.

[pupeno]

@malikoski can you elaborate on how you do that? putting the directory/resources into src/main/resources/META-INF? I may be running into this issue again (not sure, https://stackoverflow.com/questions/57617587/flyway-not-finding-migrations-when-run-from-intellij).
