Versions impacted by the bug

v5.x

What went wrong?

When calling the following line NetcdfFormatWriter.createNetNetcdfX a no such method would occur. It happened if called using "createNewNetcdf3" : NetcdfFormatWriter.Builder nc4builder = NetcdfFormatWriter.createNewNetcdf3("temp.nc");

or with "createNewNetcdf4" NetcdfFormatWriter.Builder nc4builder = NetcdfFormatWriter.createNewNetcdf4(NetcdfFileFormat.NETCDF4, "temp.nc", null);

Below are the relevant imports called:

import ucar.nc2.write.NetcdfFormatWriter.Builder;
import ucar.nc2.write.NetcdfFormatWriter;
import ucar.nc2.Dimension;
import ucar.nc2.write.NetcdfFileFormat;
import ucar.nc2.*;

The jar file that is in my lib directory is: netcdfAll-5.5.3,jar which I downloaded from here https://downloads.unidata.ucar.edu/netcdf-java/

Current build is using Ant but have also build using Maven and ran into the same issue.

Hello, I ran a quick test and I'm having a hard time reproducing the error that your seeing. I did a cursory google search of the java.lang.NoSuchMethodError and found that it's possible that there is a version mismatch between the compile time and runtime dependancies. Is it possible that you have another version of the jar file hanging around somewhere that's causing the error?
