Error when testing Go code

[sh1670]

Hi,

I am getting this error when trying to test GoLang.

Exception in thread "main" java.lang.NullPointerException: Cannot invoke "de.jplag.golang.JPlagGoListener$GoBlockContext.getEnd()" because the return value of "de.jplag.golang.JPlagGoListener.getCurrentContext()" is null

Apologies if I am missing a dependency / have not read the docs properly.

Am using Jar file and same error for 4.00 and 4.10. OS is Windows 10 and I am using Java 17 JRE

Thanks,

Sion

Think it was because some of the submissions were using post 1.17 syntax

This would make sense! Sadly, we are limited by the version of our ANTLR grammar regarding what syntax we can parse. The grammars are largely taken from https://github.com/antlr/grammars-v4/.
