Multiline expression fails: "extra token after end of expression"

[DominiqueMakowski]

This issue is a follow-up on this one, but the solutions provided there did not solve the case.

This works:

x <- julia_eval("a = 1+1; a + 2")
x

[1] 4

But this doesn't:

juliacode <- "
a = 1+1
a + 2
"

x <- julia_eval(juliacode)

Error: Error happens in Julia.
Base.Meta.ParseError("extra token after end of expression")
Stacktrace:

Trimming the string or changing the position of the opening/closing quotes did not seem to help... Any help is welcome :)

I have the same problem, and the only solution I found is to break the code in single lines julia_command("...").
