[jira] [Updated] (FLINK-31965) Fix ClassNotFoundException in benchmarks
[ https://issues.apache.org/jira/browse/FLINK-31965?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Paul Lin updated FLINK-31965:
-----------------------------
Description:
The benchmarks rely on the test jar of `flink-streaming-java`. However, the jar is set to test scope, thus not included in the packaged jar. Therefore ClassNotFoundException occurs while running the benchmarks with `java --jar xxx` command.
