Rob Young created FLINK-35732:
---------------------------------

             Summary: flink-sql-client.sh fails with ClassNotFoundException 
depending on it's location
                 Key: FLINK-35732
                 URL: https://issues.apache.org/jira/browse/FLINK-35732
             Project: Flink
          Issue Type: Bug
          Components: Deployment / Scripts
    Affects Versions: 1.19.1
            Reporter: Rob Young


To reproduce:

1. create a directory `mkdir my-flink-sql-gateway-project`
2. unpack a flink binary distribution inside that directory
3. run `./my-flink-sql-gateway-project/flink-1.19.1/bin/sql-client.sh

Expected: the SQL console starts
Actual: fails with stack trace:

{code:java}
Exception in thread "main" org.apache.flink.table.client.SqlClientException: 
Unexpected exception. This is a bug. Please consider filing an issue.

It also fails if the distribution is placed in a directory named 
`my-flink-sql-client-project`, with stacktrace:

{code:java}
Error: Could not find or load main class org.apache.flink.table.client.SqlClient
Caused by: java.lang.ClassNotFoundException: 
org.apache.flink.table.client.SqlClient
{code}

I think this is caused by the 
regexes[[1|https://github.com/apache/flink/blob/master/flink-table/flink-sql-client/bin/sql-client.sh#L71]][[2|https://github.com/apache/flink/blob/e7d7db3b6f87e53d9bace2a16cf95e5f7a79087a/flink-table/flink-sql-client/bin/sql-client.sh#L81]]
 matching all the jars in the lib dir unexpectedly. It looks like it would also 
be a problem if the flink distribution was contained in a dir named 
`my-flink-python-project` and you needed flink-python on the classpath.
