I am trying to add Log4j.jar in plugin project for logging purpose. I add the log4j jar by using build path->add external jar. After that I am trying to run the plugin project I get error
java.lang.NoClassDefFoundError: org/apache/log4j/PropertyConfigurator.
if I run the same code by using java main method it will working fine.
public HHLogger(Object className) {
DateTimeFormatter df = DateTimeFormatter.ofPattern("ddMMYYYY");
System.setProperty("filename", df.format(LocalDate.now()));
PropertyConfigurator.configure(".\\resources\\log4j.properties");
logger = Logger.getLogger(className.getClass());
}
public static void main(String args[]) {
DateTimeFormatter df = DateTimeFormatter.ofPattern("ddMMYYYY");
System.setProperty("filename", df.format(LocalDate.now()));
PropertyConfigurator.configure(".\\resources\\log4j.properties");
logger = Logger.getLogger(HHLogger.class);
logger.info(" 999 Welcom");
}
