-----------------------------------------------------------
Regarding the issue described in Jira, here are the possible solutions:
1. Try to create a new module named `connect-jvm-integration-testing` and move
the tests related to `RemoteSparkSession` into this module. At the same time,
make the `connect-jvm-integration-testing` module dependent on
`connect-client-jvm`, `connect`, and `assembly`. The feasibility of this
solution remains to be verified.
2. As I suggested in the pull request at
[https://github.com/apache/spark/pull/50396], automatically skip the tests
related to `RemoteSparkSession` when the directory
`assembly/target/scala-2.13/jars/` does not exist.
[~gurwls223] WDYT? Additionally, do you think this issue could potentially
block the release of version 4.0(Personally, I think it is)?

> Key: SPARK-51603
> URL: https://issues.apache.org/jira/browse/SPARK-51603
> Project: Spark
> Issue Type: Bug
> Components: Connect, Tests
> Affects Versions: 4.0.0
> Reporter: Yang Jie
> Priority: Major
> Labels: pull-request-available
>
> After SPARK-48936, the `assembly` module is compiled prior to
> `connect-client-jvm` to facilitate the packaging output. However, tests
> related to RemoteSparkSession in the `connect-client-jvm` module depend on
> the packaged results from the `assembly` module, specifically the JARs
> located in `assembly/target/scala-2.13/jars/`. Since the latter is a
> convention, executing
>
> {code:java}
> build/mvn clean install -DskipTests {code}
>
> will not produce any errors. But if we directly execute
> {code:java}
> build/mvn clean install {code}
> we will encounter test errors similar to the following when testing the
> `connect-client-jvm` module:
>
> {code:java}
