Why int type is convert to Integer?

Question

I faced to a problem I don't understand. I still use int type but code crashed because int is convert to Integer.

Can you explain me what is the problem ? Thanks.

Code

Caller

int excelIndex = 2
String number = CustomKeywords.'getInfo'('test', 'test', 'test', excelIndex)

Callee

@Keyword
public String getInfo(String dataTest, String dataSheet, String columnName, int excelIndex) {
    String cellContent = getValueToExcel(dataTest, dataSheet, columnName, excelIndex)
    ...
    return cellContent
}

@Keyword
def getValueFromExcel(String testDataFile, String sheet, String columnName, int rowNumber) {
    ExcelData data = initialiseDataDriven(testDataFile, sheet)
    return data.getValue(columnName, rowNumber)
}

Error

number = CustomKeywords.getInfo("test", "test", "test", excelIndex) FAILED.

Reason:
org.codehaus.groovy.runtime.InvokerInvocationException: groovy.lang.MissingMethodException: No signature of method: getValueFromExcel is applicable for argument types: (java.lang.String, java.lang.String, java.lang.String, java.lang.Integer) values: [test, test, test, 2]
Possible solutions: getValueFromExcel(java.lang.String, java.lang.String, java.lang.String, int)

您正在getInfo以静态样式调用成员方法

使getInfostatic：

public static String getInfo(String dataTest, String dataSheet, String columnName, int excelIndex) {

或者，创建的实例CustomKeywords，然后调用getInfo它：

int excelIndex = 2
def keywords = new CustomKeywords()
String number = keywords.getInfo('test', 'test', 'test', excelIndex)
