[BUG] Version conflict between SumUp SDK and Google Cloud OpenTelemetry dependencies causes runtime crash

[QuipTest]

Summary

Using SumUp Merchant SDK (7.0.0) alongside Google Cloud libraries that depend on the latest OpenTelemetry (1.42.1), causes a runtime crash due to SumUp SDK forcing older OpenTelemetry versions (1.34.1) internally. This creates a dependency version conflict that cannot be resolved via standard Gradle platform or BOM imports.

What is blocked by this issue?

2. Add Google Cloud libraries that use the latest OpenTelemetry
3. Complete a transaction using the SumUp SDK.
4. Return to your app after the payment flow is complete.
5. Observe the crash

Hi @QuipTest,

Thanks for reporting this issue, we really appreciate it. We’ll investigate and aim to include a fix in upcoming releases.

In the meantime, as a workaround for v7.0.0, you can exclude the otel library from the Google Cloud SDK to prevent the crash:

implementation('com.google.cloud:google-cloud-storage') {
    exclude group: 'io.opentelemetry'
}
