Xu Mingmin commented on BEAM-3110:
----------------------------------
Add more details on what's happening in the backend, as I see it again in
another build.
The exact root cause is file
{{META-INF/services/org.apache.beam.runners.core.construction.TransformPayloadTranslatorRegistrar}},
it exists in several libraries(some are relocated/renamed). By default
maven-shade use the first one and ignore others, but we need to merge them. So
the steps I take are:
1). make sure {{beam-runners-direct-java}} is excluded when package as it
relocates
{{org.apache.beam.runners.core.construction.TransformPayloadTranslatorRegistrar}}
which introduces additional chaos;
2). in you pom.xml, add these configuration:
{code}
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.1.0</version>
<executions>
<execution>
<id>servicesmerge</id>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer
implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"
/>
</transformers>
</configuration>
</execution>
<execution>
....
</execution>
</executions>
</plugin>
{code}
