Parse error on functions without return

[waeller]

Hi!

I think I found a bug in this plugin. This test (I added it to LuaAstScannerTest)

@Test
public void noReturn() {
  SourceFile file = LuaAstScanner.scanSingleFile(new File("src/test/resources/bugs/noreturn.lua"));
  assertThat(file.getInt(LuaMetric.LINES)).isEqualTo(7);
}

executed with this Lua file:

function doNothing()
end

function noReturn()
  doNothing()

end

fails with this console output about a parse error:

[main] ERROR org.sonar.squidbridge.AstScanner - Parse error at line 7 column 1:
1: function doNothing()
2: end
3: 
4: function noReturn()
5:   doNothing()
6: end
7: 
   ^

It is sufficient to add a return to function noReturn() and the test will succeed:

function doNothing()
end

function noReturn()
  return doNothing()
end

Regards,
Juergen
