### Delimited File Import Job
## About
The goal is to demonstrate a typical scenario of reading data
from a delimited file, processing it and writing it to another file.
## Run the sample
You can run the sample from the command line as following:
```
$>cd spring-batch-samples
# Launch the sample using the XML configuration
$>../mvnw -Dtest=DelimitedFunctionalTests#testLaunchJobWithXmlConfig test
# Launch the sample using the Java configuration
$>../mvnw -Dtest=DelimitedFunctionalTests#testLaunchJobWithJavaConfig test
```
