How to patch spring cloud data flow starter application (add oracle driver to jdbc-source app)

Question

Im trying to add an oracle jdbc driver to to the ojdbc-source from SCDF. Regarding to the official guide it should be an easy task but at runtime i always get an

NoSuchMethodError: 'void org.springframework.integration.jdbc.JdbcPollingChannelAdapter.setMaxRowsPerPoll(int)'

This is my Main-Class:

package com.example.sourcejdbcora;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Import;

@SpringBootApplication
@Import(org.springframework.cloud.stream.app.jdbc.source.JdbcSourceConfiguration.class)
public class SourceJdbcOraApplication {

    public static void main(String[] args) {
        SpringApplication.run(SourceJdbcOraApplication.class, args);
    }

}

and my pom.xml look like this:

What am i doing wrong?

You are using the old (now deprecated) app starters repository. The new apps repository is here: https://github.com/spring-cloud/stream-applications.

You need to patch the JDBC Source with the proper Oracle driver.

Here is a somewhat related answer to a different app: https://stackoverflow.com/a/67132875/2070861

You need to clone the repository and add the necessary dependencies. Then, rebuild the JDBC Source app.

You need to add the dependencies in the base supplier artifact: https://github.com/spring-cloud/stream-applications/blob/main/functions/supplier/jdbc-supplier/pom.xml

Then build the following:

./mvnw clean install -pl :jdbc-supplier
./mvnw clean install -pl :jdbc-source

That should generate the proper uber jars.
