java Intellij：如何从现有进程更新运行配置环境？

Question

我想从现有/正在运行的进程（从PID中选择）中更新给定运行/调试配置的环境变量

有插件吗？我在jetbrain仓库里找不到这样的东西

有什么足够方便的解决方案（没有变量、值对、手动复制；没有intellij重启）来更新这些环境变量

为了获得功能，我写了一个在Linux上运行的bash函数

idea_run_env()
{
  typeset rcf=${1}
  if ! [ -f "$rcf" ]; then
      echo "Can not find run configuration file '$rcf'" 1>&2*
      return 2
  fi
  typeset rcf_back=${rcf}.bak
  if (( $# > 1 )); then
    typeset pid=${2}
    # no Esc in attr value, I may/should escape/encode such values but I won't use them
    typeset to_be_bloc=$(xargs -n 1 -0 printf "%s\n" < /proc/$pid/environ | grep -a -v -E $'\e' | while IFS='=' read k v; do echo '<env name="'$k'" value="'$v'" />'; done)
    if [ -z "$to_be_bloc" ] ; then
      echo "Can not find environment for given PID '$pid'" 1>&2*
      return 2
    fi
    #typeset was_block=$(sed -e '/<envs>/,/<\/envs>/{//!b};d' "$rcf")
    typeset prefix=$(sed -e '/<envs>/q' "$rcf")
    typeset postfix=$(sed -n -e '/<\/envs>/,$p' "$rcf")
    [ -f "$rcf_back" ] || mv "$rcf" "$rcf_back"
    echo "${prefix}" > "$rcf"
    echo "${to_be_bloc}" >> "$rcf"
    echo "${postfix}" >> "$rcf"
  elif [ -f "$rcf_back" ]; then
    mv -f  "$rcf_back" "$rcf"
  else
    echo "Can not find backup to restore" 1>&2
    return 1
  fi
}
