RASCAL.MF generated by newRascalProject triggers an error in VS Code

[sungshik]

Describe the bug

Function newRascalProject in module util::Reflective produces a META-INF/RASCAL.MF that triggers an error in VS Code when a Rascal terminal is opened.

To Reproduce

1. Create a new Rascal project using function newRascalProject in module util::Reflective
2. Open the new project in VS Code
3. Open a new Rascal terminal (not necessarily using a code lens in a module)

Possible fix

This seems to be the code to generate RASCAL.MF:

rascal/src/org/rascalmpl/library/util/Reflective.rsc

Lines 407 to 412 in 42cf801

	private str rascalMF(str name)
	= "Manifest-Version: 0.0.1
	'Project-Name: <name>
	'Source: src/main/rascal
	'Require-Libraries:
	";

Adding a single quote to line 412 might be enough (but I'm not sure):

    '";

I think adding '\n" would fix this. I have the feeling we fixed this one before.. but who knows. Good catch!

[DavyLandman]

I think @sungshik proposed fix is right, as indeed, a .MF file has to end with a blank newline. no spaces no nothing.

[jurgenvinju]

Right! Let's do it.

Isn't it strange that there is no parse error in the original buggy template? Doesn't every non-escaped newline inside a string come with a single quote?

[sungshik]

Right! Let's do it.

Ok, doing this now Done. See #2080.
