Hi, In my project I have a flink-table wrapper around the functionality offered by my project. Since Flink 1.17.0 the normal Flink wrapper still works fine, yet the flink-table wrapper fails during the build with mostly:

Error:  nl.basjes.parse.useragent.flink.table.TestTableFunctionClientHints.testMapFunctionReturnMap  Time elapsed: 5.42 s  <<< ERROR!

I have the same problem

i guess it could relate to update of Calcite but sticking to the older janino version in 1.17.0 however not sure... it would be great to have something reproducible. i tried with https://github.com/nielsbasjes/yauaa however currently locally it fails

Could not resolve dependencies for project nl.basjes.parse.useragent:yauaa-logstash:jar:7.17.1-SNAPSHOT: The following artifacts could not be resolved: org.logstash:logstash-core:jar:8.6.2, nl.basjes.parse.useragent:yauaa:jar:7.17.1-SNAPSHOT: org.logstash:logstash-core:jar:8.6.2 was not found in <https://repo.maven.apache.org/maven2> during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced

what am i doing wrong?

@Sergey Nuyanzin That dependency problem has to do with maven 3.9.0 and a problem with the maven install plugin. For this case you can just remove the UDFs you are not interested in https://github.com/nielsbasjes/yauaa/blob/main/udfs/pom.xml#L79

Thanks, i was able to reproduce it. It looks like Calcite expects methods with 2+ args for

Metadata

and caches them. At the same time for some reason JaCoCo generates

$jacocoInit()

like e.g.

private static boolean[] org.apache.calcite.rel.metadata.BuiltInMetadata$Predicates$Handler.$jacocoInit()

Seems it is the reason, I disabled JaCoCo for flink-table and it starts passing.

Yes, that did the trick. Thank you !

Hi @Niels Basjes, I’m facing the same issue with calcite Metadata.

Can you please share how you added the exclusion?
