Hi, I am interested to contribute to this issue
https://issues.apache.org/jira/browse/BEAM-3658 I have followed the contribution guide and was able to build the project locally using gradlew commands. I wanted to debug and trace the issue further by running the tests locally using Intellij Idea but I am getting following errors. I looked up the docs related to running tests ( https://cwiki.apache.org/confluence/display/BEAM/Run+a+single+unit+test) and common IDE errors ( https://cwiki.apache.org/confluence/display/BEAM/%28FAQ%29+Recovering+from+common+IDE+errors) but have not found similar errors. Error:(632, 17) java: cannot find symbol symbol: method apply(org.apache.beam.sdk.transforms.Values<java.lang.Object>) location: interface org.apache.beam.sdk.values.POutput Error:(169, 26) java: cannot find symbol symbol: class PCollection location: class org.apache.beam.sdk.transforms.Watch Error:(169, 59) java: cannot find symbol symbol: class KV location: class org.apache.beam.sdk.transforms.Watch Please let me know if you have feedback.
