How Do I use correctly Java CSVtoBean

I am using Jdeveloper to create a small software which reads Weatherdata from a .csv file and proceses it .

Unfortunatelly i am stuck at the first step, reading data from file . Keep getting back the following Exception : Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/collections4/MultiValuedMap

Please see attached my progress so far , please feel free to edit or comment .

public class Main {

/**

* @param args

*

*/

@SuppressWarnings({"rawtypes", "unchecked"})

public static void main(String[] args) throws IOException {

String fileName = "C:\\JDeveloper\\mywork\\Csv reading\\Project1\\wdata1.csv";

Path myPath = Paths.get(fileName);

try (BufferedReader br = Files.newBufferedReader(myPath, StandardCharsets.UTF_8)) {

HeaderColumnNameMappingStrategy<Read> strategy = new HeaderColumnNameMappingStrategy<>();

strategy.setType(Read.class);

CsvToBean toBean = new CsvToBeanBuilder(br).withType(Read.class)

.withMappingStrategy(strategy)

.withIgnoreLeadingWhiteSpace(true)

.build();

List<Read> Data = toBean.parse();

Data.forEach(System.out::println);

}

}

Also have a different class with the column names :

public class Read {

@CsvBindByName

private String stationid;

@CsvBindByName

private String datestamp;

@CsvBindByName

private double wgust;

@CsvBindByName

private int wdir;

// get, setters here

}

I have tried to import the neccesary files, tried most of the solution i found, but none of them seems to be working . I am really new to this, i would appreciate all the helps !

The file I am using looks like this :
