rajkgupt opened a new issue, #30992:
URL: https://github.com/apache/beam/issues/30992
### What happened?
Below are few issues and observations noticed:
1. I ran the example from [2] and it seems BOM is not included in generated
build.gradle.kts file [6]
Please clarify/fix below couple of questions from it.
- a. is it intentional to not have BOM dependency, like
```<libraries-bom.version>26.32.0</libraries-bom.version>``` found in
corresponding pom.xml file?
- b. the generated gradle file only has dependency for
```org.apache.beam:beam-runners-google-cloud-dataflow-java:2.55.1```, but from
[1] we can see other two i.e. ```beam-sdks-java-io-google-cloud-platform``` &
```beam-sdks-java-core``` are also required. I was able to run without these
two dependencies but wanted to confirm on these two dependencies?
2. sample dataflow runner command in [2] needs to be updated to add
```--runner=DataflowRunner``` inside --args
3. After following the steps given in apache beam site [3] and running
command [4], I get error ```Exception in thread "main"
java.lang.IllegalArgumentException: Unknown 'runner' specified
'DataflowRunner', supported pipeline runners [DirectRunner, PortableRunner,
TestUniversalRunner]```
Then I ran maven package command with dataflow-runner like [5] and it
worked
Also the output variable needs to be added in the command like
```--output=gs://<YOUR_GCS_BUCKET>/output```
