[Bug]: NoClassDefFound IOUtils

Module

Core

Testcontainers version

testcontainers 2.0.3 / mariadb 1.21.3

Using the latest Testcontainers version?

Yes

Host OS

Linux

Host Arch

ARM

Docker version

Docker version 27.3.1, build ce12230

What happened?

After switching from mariadb 1.21.3 to 2.0.3, the following exception occurs due to "shaded IOUtils" when using SQL Script Imports in tests.

The following worked before migration to the new splittet version numbers:

try (Connection con = org.springframework.jdbc.datasource.DataSourceUtils.getConnection(ds)) {
    org.springframework.jdbc.datasource.init.ScriptUtils.executeSqlScript(con, res);
}

Before:

            <dependency>
                <groupId>org.testcontainers</groupId>
                <artifactId>mariadb</artifactId>
                <version>1.21.3</version>
            </dependency>

Now:

            <dependency>
                <groupId>org.testcontainers</groupId>
                <artifactId>mariadb</artifactId>
                <version>2.0.3</version>
            </dependency>

application.properties:
jdbc:tc:mariadb:11:///databasename

Hi, please check the release notes when updating versions. As stated in release notes for version 2.0.0, all modules have been prefixed with testcontainers-. So, instead of using mariadb 1.21.3 use testcontainers-mariadb 2.0.3, which is aligned with testcontainers 2.0.3.

Thank you very much, must have overseen this. It works:

            <dependency>
                <groupId>org.testcontainers</groupId>
                <artifactId>testcontainers-mariadb</artifactId>
                <version>2.0.3</version>
            </dependency>
