VisualizaçõesProblem setting up H2 init runscript. File is not found when script is not in classpath root folder while using java modular system
Following accepted answer for question regarding how to init runscript from resources folder: problem with INIT=RUNSCRIPT and relative paths.
Connection String:
jdbc:h2:mem:;INIT=RUNSCRIPT FROM 'classpath:desktop/core/database/databaseCreation.sql'
However i get exception that file is not found even when file is present.
Exception:
org.h2.jdbc.JdbcSQLNonTransientException: IO Exception: "java.io.FileNotFoundException: resource /desktop/core/database/databaseCreation.sql"; "classpath:desktop/core/database/databaseCreation.sql"; SQL statement:
RUNSCRIPT FROM 'classpath:desktop/core/database/databaseCreation.sql' [90031-210]

Trying to access file using getResource (DatabaseManager class is in desktop.core.database package) tells that file exists:
String file = DatabaseManager.class.getResource("databaseCreation.sql").getFile();
boolean yes = new File(file).exists(); // yes is true
Tried on both Windows(10) and Linux (Kubuntu) platform and using h2 of version 2.1.210.
UPDATE #1
File is found when it is in root classpath folder classpath:databaseCreation.sql, but still not when under some subfolder like desktop/core/database.
Appending '/' before first subfolder does not work.
Tried to put sql file to all folders.
'classpath:desktop/core/database/databaseCreation.sql' does not work
'classpath:desktop/core/databaseCreation.sql' does not work
'classpath:desktop/databaseCreation.sql' does not work
only this works
'classpath:databaseCreation.sql'
Without using classpath:
Without using classpath, the file can be in any subfolders, but this way, i need to use absolute path to the file:
jdbc:h2:mem:;INIT=RUNSCRIPT FROM '<absolute path here>'
Leaving the question open since the referenced question has outdated answer, which is not working on current H2 version and want to know how to get it work using classpath.
UPDATE #2
In order to replicate, you need to use java modular system (module-info.java) in the project.

UPDATE: (module-info.java)
Per your comment, your original setup used JDK 9+ modules. That's a complex and confusing topic. It would be easiest to simply remove module-info.java and not use modules. If you intend to use modules and keep resources in a separate directory (module), there are multiple options with no one clear choice. Perhaps the easiest option would be to open the "package" containing the resource. Something like this worked in my local test:
module myAppModule {
exports desktop.core.database;
opens desktop.core.database;
requires java.sql;
requires org.junit.jupiter.api;
}

I could not replicate your problem using a very simple maven setup with only the H2 runtime as a dependency (same version, 2.1.210) along with JUnit 5. It worked as expected.
The stack trace shows this is being run as a test from within Eclipse. I could replicate your issue exactly in Eclipse if I manually added src/main/resources as a Java Build Path source folder, but with an exclusion of **/ which would exclude subdirectories of resources.
If you are using maven, perhaps try running on command line with mvn test to verify that it is not your Eclipse setup.
Otherwise, you will need to post more info to get help.
