Looking at your pom.xml seems the problem is the dependecy:

<dependency>
     <groupId>org.springframework.batch</groupId>
     <artifactId>spring-batch-core</artifactId>
     <version>4.3.8</version>
</dependency>

Starting from spring-batch 5.0 in class ItemWriter the method signature for write changed from this:

void write(List<? extends T> items) throws Exception;

Spring batch 4.3.x -> https://github.com/spring-projects/spring-batch/blob/4.3.x/spring-batch-infrastructure/src/main/java/org/springframework/batch/item/ItemWriter.java

to this:

void write(@NonNull Chunk<? extends T> chunk) throws Exception;

Spring batch 5.0.x -> https://github.com/spring-projects/spring-batch/blob/5.0.x/spring-batch-infrastructure/src/main/java/org/springframework/batch/item/ItemWriter.java

Maybe you are using a spring-boot 3.x+ which have spring-batch dependecy 5.x+, forcing into pom.xml version 4.3.8 you are causing a conflict. Try to remove version forced like other dependecies.

NOTE: you can remove the entire dependency because spring-boot-starter-batch import spring-batch-core
