I'm begginer in Latex and I get this error when I compile my file

LaTeX Error: There's no line here to end.

following is the code that I used :

\documentclass[12pt,a4paper]{article}
  \usepackage[T1]{fontenc}
  \usepackage{array}
  \usepackage{url}
  \usepackage{hyperref}

  \input{style/packages.tex}
  \input{style/style.tex}
  \input{title/title.tex}

  \begin{document}
     \pagestyle{fancy}
     \maketitle
     \newpage
     \input{body/pages/remerciements.tex} \newpage
     \input{body/pages/abstract-fr.tex} \newpage
     \input{body/pages/abstract-en.tex} \newpage
     \renewcommand{\contentsname}{Table of Contents} 
     \tableofcontents \newpage
     \listoffigures
     \listoftables \newpage
     \input{body/pages/titre1/titre1.tex} \newpage
     \input{body/pages/titre2/titre2.tex} \newpage
     \input{body/pages/titre3/titre3.tex}   \newpage
     \input{body/pages/titre4/titre4.tex}   \newpage
     \input{body/pages/titre5/titre5.tex}   \newpage
     \input{body/pages/conclusion.tex} \newpage
     \bibliographystyle{unsrt}
     \bibliography{bibliografie}  \newpage
     \appendix
     \input{appendix/titreA.tex}
  \end{document}

This is the content of "title.tex"

Can someone tell me where is the problem ?

Best Answer

The \\ here

\vspace{\stretch{2}}
\\

is spurious and will always generate this error, simply delete it.

Note also 

{\LARGE \bf \@title\\}

should be

{\normalfont\LARGE \bfseries \@title\par}

so that the title is set with a baseline spacing appropriate for the size of the text.
