intellij-idea - 如何在 Ubuntu 的 IntelliJ 项目中修复这些警告 "External file changes sync may be slow"和 "The current inotify(7) watch limit is too low"

Question

当我打开我的项目时，我在 IntelliJ IDEA 中收到两条警告消息。

1. IntelliJ IDEA cannot receive filesystem event notifications
for the project. Is it on a network drive?

2. The current inotify(7) watch limit is too low.

注意:我使用的是 UBUNTU 20.04 LTS

正如在 this link 中分享的那样:
添加新的conf文件..

$ sudo touch /etc/sysctl.d/60-jetbrains.conf

打开文件并添加这些行

# Set inotify watch limit high enough for IntelliJ IDEA (PhpStorm, PyCharm, RubyMine, WebStorm).
# Create this file as /etc/sysctl.d/60-jetbrains.conf (Debian, Ubuntu), and
# run `sudo service procps start` or reboot.
# Source: https://confluence.jetbrains.com/display/IDEADEV/Inotify+Watches+Limit
# 
# More information resources:
# -$ man inotify # manpage
# -$ man sysctl.conf # manpage
# -$ cat /proc/sys/fs/inotify/max_user_watches # print current value in use

fs.inotify.max_user_watches = 524288

让我们重新启动系统

$ sudo sysctl -p --system
