What happened?

There is an issue using ScriptUtils.runInitScript from database-commons version 1.21.3 (the latest available version) after upgrading testcontainers to 2.0.1. It seems that apache commons has been removed from shaded in the latest version.

version.org.testcontainers..testcontainers=2.0.1

version.org.testcontainers..jdbc=1.21.3

Relevant log output

Make sure all your dependencies are using 2.0.1. See you are using different versions

version.org.testcontainers..testcontainers=2.0.1

version.org.testcontainers..jdbc=1.21.3

I have created an example with MySQLContainer and everything is working fine

MySQLContainer mysql = new MySQLContainer("mysql:8.0.28")
                .withInitScript("init.sql")

Otherwise, please submit a project that reproduces the issue.

2.0.1 is not released @eddumelendez same issue here, can't find it for any other than the core container

[lobaorn-bitso]

Found it, it all now have testcontainers- prefix for some reason: https://mvnrepository.com/artifact/org.testcontainers/testcontainers-database-commons/2.0.1

Not sure if its intended.

[lobaorn-bitso]

Yes, it is intended, as per release docs: https://github.com/testcontainers/testcontainers-java/releases/tag/2.0.0

All modules are now prefixed with testcontainers-. For example, org.testcontainers:mysql is now org.testcontainers:testcontainers-mysql

cc @westernsam @FunkyMuse @MRyves

Lets just use the OpenRewrite recipe: https://docs.openrewrite.org/changelog/8-64-0-Release

[westernsam]

Thanks @lobaorn-bitso - that resolves my issue. Will remember to check release notes in future!
