Tomo Suzuki commented on BEAM-9304:
-----------------------------------
The situation will be fixed by Beam 2.20.0. Dependency trees of the sample
project:
* With 2.18.0 and 2.19.0, it picks up
io.opencensus:opencensus-api:jar:0.*15*.0 through
com.google.cloud.bigtable:bigtable-client-core:jar:1.8.0
2.18.0 [https://gist.github.com/suztomo/6217ae075b48bafc504e47af0536d973]
2.19.0 [https://gist.github.com/suztomo/c6a1119be1926fd0ae382d4c43dac454]
* With 2.20.0-SNAPSHOT and With 2.21.0-SNAPSHOT, it picks up
io.opencensus:opencensus-api:jar:0.24.0 through com.google.api:gax:jar:1.53.0
2.20.0-SNAPSHOT
[https://gist.github.com/suztomo/4805beec96d406b50f3f485c017961d2]

> beam-sdks-java-io-google-cloud-platform imports conflicting versions for
> BigTable and Spanner
> ---------------------------------------------------------------------------------------------

> Key: BEAM-9304
> URL: https://issues.apache.org/jira/browse/BEAM-9304
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp
> Affects Versions: 2.18.0
> Reporter: Knut Olav Loite
> Assignee: Chamikara Madhusanka Jayalath
> Priority: Critical
> Fix For: 2.20.0
>
> Attachments: SpannerRead.java, pom.xml
>
>
> If I include `beam-sdks-java-io-google-cloud-platform` version 2.18.0 in a
> project and try to use `SpannerIO`, the exception
> `java.lang.NoClassDefFoundError: io/opencensus/trace/Tracestate`. This seems
> to be caused by conflicting versions of `io.opencensus:opencensus-api` being
> included by the BigTable client and the Spanner client. BigTable imports
> version 0.15.0. Spanner depends on 0.18.0, but as they are at the same level
> in the dependency tree and BigTable is defined first, version 0.15.0 is used.
>
> The workaround for this issue is to exclude the BigTable client in the
> project pom in order to be able to use SpannerIO.
>
> An example pom and simple Java class are included. If the commented exclusion
> of the BigTable client is removed, the example will run without problems. The
> example will also run without problems on Beam version 2.17 without the
> exclusion.
