调试：java.lang.NoSuchMethodError

Question

I encountered a java.lang.NoSuchMethodError when running a program.

This link explained the error very clearly.

I am trying to debug this exception in Eclipse Kepler. The link recommends setting the JVM options -Dibm.cl.verbose=[class name] , and -verbose:dynload .

I set these options under Run As -> Run Configurations -> Arguments -> VM arguments. However, after setting the options the JVM is not outputting any additional debug information.

Exception in thread "main" java.lang.NoSuchMethodError: [package].Argument.getConsole()Lcom/beust/jcommander/internal/Console;

Why is the JVM not outputting the expected debug information?

Answer 1

According to the code on this page : https://github.com/cbeust/jcommander/blob/master/src/main/java/com/beust/jcommander/WrappedParameter.java

Jcommander can throw a NoSuchMethodException itself if you've led it to expect a list (that should have a 'put' method) but give it a type that doesn't have that method.

[SOLVED]

So it was a conflict with some dependency issue. Basically I had Maven version 1.17 and 1.30 somehow. I deleted the older one and the problem was resolved.
