Unable to have a Value argument-provider for a string parameter in spoofax.cfg

[arnoudvanderleer]

Summary

Adding a Value argument-provider for a string parameter in spoofax.cfg gives an error.

What you did

I added the following piece of code to spoofax.cfg (inside command-def -> parameters)

    asdf = parameter {
      type = java String
      argument-providers = [Value("Hello")]
    }

What you expected to happen

I expected the program to not give an error, and pass the string parameter to the command/task.

What actually happened

I got an error:

'CFG editor update' has encountered a problem. An internal error occurred during "CFG editor update".

An internal error occurred during: "CFG editor update".
