Make sure the class files that you are actually running are updated when you compile. share|improve this answer answered Aug 29 '08 at 20:14 Vetle 1,35311626 We recently discovered the cause of one of these and it turned out the build proc

Exception in thread "main" How to solve java.lang.NoSuchMethodError: main Exception in thread "main" java.lang.NoSucMethodError comes when Java code tries to call a method which is not existed on a class, this could be either static or http://javarevisited.blogspot.com/2012/03/javalangnosuchmethoderror-main.html non static method. most common manifestation of java.lang.NoSuchMethodError is running a class which https://docs.oracle.com/javase/7/docs/api/java/lang/NoSuchMethodError.html doesn't have main method in Java. In this article we will see what is "java.lang.NoSuchMethodError: main Exception in thread "main"" , Why does java.lang.NoSuchMethodError comes and how to solve java.lang.NoSuchMethodError in Java. What is "java.lang.NoSuchMethodError: main Exception in thread "main"" This is a manifestation of NoSuchMethodError in Java and complaining about "main" which no such is name of method JVM tries to call but doesn't find in offending class. "java.lang.NoSuchMethodError: main Exception in thread "main" can come due to various reasons like: 1) Class which you are trying to run doesn't have main method. 2) Signature of main method is not correct . See here for all possible signature of main method in Java. Example of "java.lang.NoSuchMethodError: main Exception in thread no such method "main" To better understand NoSuchMethodError in Java let's see some common examples of java.lang.NoSuchMethodError and find out how and when they come: 1) try to run a java class which doesn't have a main method: public class Loan{ public String getPersonalLoan(){ return "Personal Loan"; }; } 2) Now compile this class it should compile without any error: user@home:~/java javac Loan.java 3) Run as "java Loan" user@home:~/java java Loan java.lang.NoSuchMethodError: main Exception in thread "main" There are very few scenarios on which java.lang.NoSuchMethodError come during runtime because compiler is able to check this error and flag it if doesn't found the proper method except main which is optional method and only checked by JVM during runtime. As I said earlier Another possible cause of "java.lang.NoSuchMethodError: main Exception in thread "main" is that you have main method in class but signature of main method is not correct. to test this scenario let's add a main method in Loan.java public class Loan{ public String getPersonalLoan(){ return "Personal Loan"; }; public static void main(String args){ System.out.println("Inside main in Java"); } } Now compile and
