zentol opened a new pull request #7456: [FLINK-11289][examples] Rework examples to account for licensing URL: https://github.com/apache/flink/pull/7456 ## What is the purpose of the change This PR adds separate fat-jar modules for the twitter and state-machine examples so that we can properly handle licenses for them. These jars have been bundling dependencies without any license files, requiring us to handle these dependencies in the flink-dist NOTICE-binary manually. These modules work similar to the `flink-sql-connector` modules in that they do not contain any code themselves; they are purely used for assembling a jar with proper licensing. These jars are not deployed to maven, and only included in flink-dist. Additionally this PR fixes an issue where transformers defined child-modules would disabled the NOTICE file transformer. ## Brief change log * add new `flink-examples-build-helper` module * add sub modules for each example * add licensing to new modules * move shade-plugin configuration for jar assembly from flink-examples-streaming to respective module * update flink-dist assembly to account for new modules ## Verifying this change Manually verified. Ran both examples on a local cluster and inspected jar contents. The state-machine jar no longer includes classes from flink-core that were accidentally pulled in. The Twitter jar no longer bundles chill that was accidentally pulled in.
