on-resolvable parent POM for io.confluent:kafka-connect-storage-common-parent:6.0.0?

[Adeljoo]

I imported the code into eclipse as a maven project and I got the following error for all the projects. Any thoughts of how to solve this?
Is there a way to run this in the eclipse or I have to run it via terminal?

`Project build error: Non-resolvable parent POM for io.confluent:kafka-connect-storage-common-parent:6.0.0-

@Adeljoo Did you read the FAQ? https://github.com/confluentinc/kafka-connect-storage-common/wiki/FAQ

[Adeljoo]

I have followed this instruction and was able to have maven clean without any error in Eclipse, Build success.
Building kafka-connect-storage-partitioner 6.0.0-SNAPSHOT [INFO] --------------------------------[ jar ]--------------------------------- [INFO] [INFO] --- maven-clean-plugin:3.0.0:clean (default-clean) @ kafka-connect-storage-partitioner --- [INFO] Deleting /home/ameneh/eclipse-workspace/kafka-connect-storage-common-acc/partitioner/target [INFO] ------------------------------------------------------------------------ [INFO] BUILD SUCCESS

But When I do other build lifecycles like Maven build then specify a goal as clean or validate then I get the following error:

I don't use Eclipse. I just build in the terminal directly.

partitioner builds fine for me

Do you really need to build the master branch, though?

[Adeljoo]

Not really, I need to extend the partitioner. I assume one of the releases also works, am I right? also, this sentence is a bit difficult for me to understand. Should I perform all the previous steps in the folder where I download the master branch?
Then, to build Kafka Connect Storage Common modules and make them available to storage sink connectors, do the same on the current repo:

Next question, for the other branches, I do not need to add the dependencies? I just run in the termininal and it will work magiclly?

[OneCricketeer]

I need to extend the partitioner.

You don't need to build this project to create your own partitioner.

Add this to your Maven project

<dependency>
  <group>io.confluent</group>
  <artifactId>kafka-connect-storage-partitioner</artifactId>
  <verison>5.4.1</version>
</dependency>

Then you can have YourClass implements Partitioner

You can also download the JARs here - https://mvnrepository.com/artifact/io.confluent/kafka-connect-storage-partitioner?repo=confluent-packages

[Adeljoo]

Thank you. I added the jar file to the build path but still get this error

Missing from ... Maven Central? Right... Confluent has their own repo

[Adeljoo]

Greate. I will post the pom that I use, may someone have the same issue.
One more question, when I build a custom partitioner, I need to export the java class to the single jar or the whole package must be export as a jar? Sorry, I am super new to this part.

Here is the final pom:

I was able to add a custom partitioner.

Fantastic. Feel free to close the issue @Adeljoo
