Spring Cloud Data Flow with Kubernetes DeployerPartitionHandler throws java.lang.ClassNotFoundException: io.fabric8.kubernetes.api.model.batch.Job

I am trying to run a basic Spring Batch task with partition on Docker Desktop Kubernetes. I have installed SCDF using helm charts and was able to run a basic task to ensure that SCDF installation is working. When I try to run a batch job with 2 workers. I am getting the following error in the manager pod.

How to import org.springframework.web.servlet.function package in a Spring Boot project?

I have downloaded a Spring boot demo project with the latest Spring version (2.2.0 M1). However, I am not being able to find the package org.springframework.web.servlet.function in it. Can anyone please shed light on this?

And, here is my application main class.

#EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
#SpringBootApplication
public class DemoApplication {
public static void main(String[] args) {
SpringApplication.run(DemoApplication.class, args);
}
}
I am not being able to find the org.springframework.web.servlet.function package. But, that is vitally important since I want to access the RouterFunction.

Maven: how to configure to use an artifact present locally (~/.m2/repository) before trying online?

Having two maven projects locally, namely Authentication and Commons,
I need to use Commons as a dependency in the Authentication's pom.xml,
which is correctly deployed in the local repository at ~/.m2/repository after running mvn clean install in the Commons root directory.
However I'm not getting how to stop it trying to download this local dependency from online, when I run maven clean install in the Authentication root directory.
Here the error I get:
[ERROR] Failed to execute goal on project authentication: Could not resolve dependencies for project io.project:authentication:jar:0.0.1-SNAPSHOT: Failure to find io.project.commons:project-commons:jar:0.0.1.RELEASE in https://repo.spring.io/snapshot was cached in the local repository, resolution will not be reattempted until the update interval of spring-snapshots has elapsed or updates are forced

Isn't it possible to config the pom to first look at the local repository, then to go search it online?

Look at your coordinates. In authentication, you depend on io.project.commons:project-commons:
<dependency>
<groupId>io.project.commons</groupId>
<artifactId>project-commons</artifactId>
<version>0.0.1.RELEASE</version>
</dependency>
But the actual coordinates on the commons project are io.project:project-commons:
<groupId>io.project</groupId>
<artifactId>project-commons</artifactId>

Can't connect to PostgreSQL with Spring Boot 1.5.x

I tried to create an empty spring boot 1.5 application with PostgreSQL 9.4 and 9.6 and i got this exception. BUT it works fine when i use Spring Boot 2.0.x ?!
Why is it telling me my password is incorrect ? It works fine when i connect on pgadmin 3 or 4.
this is the error

Spring boot
The DataSource bean is configured here:
#SpringBootApplication

{
private static Class<DemoApplication> applicationClass = DemoApplication.class;
public static void main(String[] args) {
SpringApplication.run(applicationClass, args);
}

}
#Bean
public DataSource dataSource()
{
JndiObjectFactoryBean jndiObjectFB = new JndiObjectFactoryBean();
jndiObjectFB.setJndiName("jdbc/test.sqlite");
jndiObjectFB.setResourceRef(true);
jndiObjectFB.setProxyInterface(javax.sql.DataSource.class);
return (DataSource) jndiObjectFB.getObject();
}
}
The DataSource should be used in the CartDao
public interface CartDao extends CrudRepository<Cart, Long> {
Cart getById(long id);
}
The application properties are empty.

It sounds like what is happening is you spring is not able to instantiate a connection to the datasource.
Some possible causes for that might be:
maybe the sqllite dbfile is not reachable
maybe its location misconfigured in the context.xml
maybe check the permissions and credentials
To further determine the issue, I would first try to determine why spring ins't able to instantiate the datastore by enabling debug logging:
