src is undefined

Issue Type

• [x] Bug Fix

Current/Missing Behaviour

I'm getting the error: "Fatal error: Expected src to be a string or an array of strings. Got undefined instead.", when running nwjs:src.

Expected/Proposed Behaviour

src is set to the string, which is set in the code.

nwjs: {
    options: {
            xxx
    },
    src: "./build/src_<%= packageconfig.language %>/**/*",
    },

Additional Info

I get the same error from version 4.6.1 to 4.7.7. Version 4.6.0 gives a totally different error.

The grunt-file works in version 3.7.1 without problems.

• Operating System: docker build linux/amd64
• Node version: 22
• NW.js version: 0.88.0

@missma19 What version of grunt-nw-builder did you upgrade from? If you have glob enabled, then wrap the src string in an array:

src: [ "./path/to/package.json", "./build/src_<%= packageconfig.language %>/**/*" ]

Also copy of the stack trace would help.

Hi, I upgraded from 3.6.0. Glob is not enabled. (There is a mistake in the readme. It says twice "when glob is enabled")

I don't know exactly what you mean with stack trace, but i guess this is what you want.
