Failed to configure data source from application.yml in SpringBoot Kotlin - spring-boot

Question

I am using application.yml file to configure data source. When I run the jar file, I get the exception. 

It works fine if I run project in IntelliJ (run button)
Command I use to build and run jar
./gradlew build -x check
java -jar build/libs/UrlShortener-0.0.1-SNAPSHOT-plain.jar
application.yml
spring:
datasource:
url: jdbc:postgresql://localhost:5332/dbName
username: username
password: password
driverClassName: org.postgresql.Driver
Exception
05:13:50.339 [main] ERROR org.springframework.boot.SpringApplication - Application run failed
org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception with message: Failed to determine a suitable driver class

})
}

}
tasks.withType<KotlinCompile> {
kotlinOptions {
freeCompilerArgs = listOf("-Xjsr305=strict")
jvmTarget = "17"
}
}
tasks.withType<Test> {
useJUnitPlatform()
}
But if I configure through kotlin, it works
#Configuration
class Config {
#Bean
fun getDataSource(): DataSource {
val dataSourceBuilder = DataSourceBuilder.create()
dataSourceBuilder.driverClassName("org.postgresql.Driver")
dataSourceBuilder.url("jdbc:postgresql://localhost:5332/dbName")
dataSourceBuilder.username("username")
dataSourceBuilder.password("password")
return dataSourceBuilder.build()
}
}

taking out your customisation for jar seems to resolve the issue.
//tasks.withType<Jar> {
// manifest {
// attributes["Main-Class"] = "url.shortener.UrlShortenerApplicationKt"
// }
// duplicatesStrategy = DuplicatesStrategy.EXCLUDE
// from({
// configurations.runtimeClasspath.get().filter { it.name.endsWith("jar") }.map { zipTree(it) }
// })
//
//}
