link3280 opened a new pull request #11934:
URL: https://github.com/apache/flink/pull/11934
## What is the purpose of the change
This PR hardens BashJavaUtilsITCase.
In BashJavaUtilsITCase, runBashJavaUtilsCmd.sh locates flink-dist.jar by
`find` with pattern `flink-dist*.jar`, but it doesn't filter out the
flink-dist*-source.jar built by maven and the flink-dist jar in the original
bin directory, so it might get 3 jars as the result, which might break the
command depends on it.
For instance, the result of `find` can be:
```
project_dir/flink-dist/src/test/bin/../../../target/flink-dist_2.11-1.10.0-sources.jar
project_dir/flink-dist/src/test/bin/../../../target/flink-1.10.0-bin/flink-1.10.0/lib/flink-dist_2.11-1.10.0.jar
project_dirflink-dist/src/test/bin/../../../target/flink-dist_2.11-1.10.0.jar
```
## Brief change log
Restrict the search scope to `-maxdepth 1` under `target` directory, and
join the jars found with `:` before adding them to the classpath.
