Latex 无法计算\cvitem上的填充

我对乳胶很陌生。我试图缩小

\newenvironments{cvitems1}

上方和下方的间距。我不确定这样做是否正确，但简历中所有项目符号列表都命名为

\cvitems

，我只想修改一个项目符号列表。我将

Skills.tex

部分中的项目列表重命名为

\cvitems1

，尝试只调整间距。没用

% Define an environment for cvskill
\newenvironment{cvskills}{
  \begin{cente1
    \setlength\tabcolsep{1ex}
    \setlength{\extrarowheight}{0pt}
    \begin{tabular*}{\textwidth}{@{\extracolsep{\fill}} r L{15.2cm}}
}{
    \end{tabular*}
  \end{center}
}
% Define a line of cv information(skill)
% Usage: \cvskill{<type>}{<skillset>}
\newcommand*{\cvskill}[2]{
    \skilltypestyle{#1} & \skillsetstyle{#2} 
  \\
}

% Define an environment for cvitems(for cventry)
\newenvironment{cvitems}{
  \vspace{-4mm}
  \begin{justify}
  \begin{itemize}[leftmargin=2ex, nosep, noitemsep]
    \setlength{\parskip}{0pt}
    \renewcommand{\labelitemi}{\bullet}
}{
  \end{itemize}
  \end{justify}
  \vspace{-4mm}
}

% Define an environment for cvitems1(for cventry)
\newenvironment{cvitems1}{
    \vspace{-8mm}
    \begin{justify}
    \begin{itemize}[leftmargin=2ex, nosep, noitemsep]
        \setlength{\parskip}{0pt}
        \renewcommand{\labelitemi}{\bullet}
}{
    \end{itemize}
    \end{justify}
    \vspace{-8mm}
}

请制作一个可编译的

\cvsection{Skills}
\begin{cventries}
  \cventry
    {}
    {}
    {}
    {}
    {
      \begin{cvitems1}
        \item {C++, Java, VB.net, Python, HTML}
        \item {Linux, Windows, SSH, working in CLI}
        \item {Wireshark, Nmap, VMware, VirtualBox, Adobe Premiere, Adobe Photoshop}
        \item {Eclipse, Visual Studio, IntelliJ}
      \end{cvitems1}
    }
\end{cventries}
