Description

When spark 3 was introduced, the spark structured streaming runner sources were moved to spark/2 module (https://github.com/apache/beam/pull/14216/commits/9c0f6088078563ece6dc60877b0dcb320f1c9bfe) and the build system was changed. Now spark runners are built per spark version module (2 or 3) and the version specific sources are copied from spark-version/src to spark-version/build/source-overrides and gradle source sets are set to main-spark src + spark-version/build/source-overrides. The problem is that  spark-version/src is outside of gradle source sets and thus the IDE does not compile this source, that is not an issue when there is very few classes but in the case of the spark structured streaming runner, it is the whole runner code that is rendered invisible to the IDE which is impracticable for runner development.

 

As ide project settings are gerenated with gradle import, changing the project settings manually would not work as the settings would be erased with each gradle import
