Hi guys. I keep getting this error while trying to run maven:

The following artifacts could not be resolved: org.apache.flink:flink-statebackend-rocksdb:jar:1.18-SNAPSHOT (absent): Could not find artifact org.apache.flink:flink-statebackend-rocksdb:jar:1.18-SNAPSHOT

Is 1.18 released?

Look up: https://nightlies.apache.org/flink/flink-docs-master/docs/ops/state/state_backends/

I think that in order to use unreleased versions you need to enable maven to do so

how?

x-SNAPSHOT

dependencies are published into separate maven repository. To get snapshot versions of Flink you need to specify repositories containing required artifacts in your pom.xml

<repositories>
    <repository>
      <id>apache.snapshots</id>
      <name>Apache Snapshot Repository</name>
      <url><https://repository.apache.org/snapshots></url>
      <releases>
        <enabled>false</enabled>
      </releases>
    </repository>
  </repositories>

You need to tell maven where to pull from and how. There should be like a settings.xml somewhere

@Aleksandr Pilipenko thanks but this time I get this error: Caused by:

java.lang.NoClassDefFoundError: org/rocksdb/FlinkCompactionFilter$TimeProvider

at org.apache.flink.contrib.streaming.state.RocksDBKeyedStateBackendBuilder.build(RocksDBKeyedStateBackendBuilder.java:290)

I have already added:

<dependency>

<groupId>org.rocksdb</groupId>

<artifactId>rocksdbjni</artifactId>

<version>8.1.1.1</version>

</dependency>

Flink use modified rocksdb version - https://github.com/apache/flink/blob/master/flink-state-backends/flink-statebackend-rocksdb/pom.xml#L56-L60

@*Aleksandr Pilipenko* 👏 Thank you very much!
