Here's how to use idea2021.3.

IDEA versions before 2021.3 can use retry scripts. Recently, IDEA officially released a new version of 2021.3. The original author does not maintain the upgrade reset script, so he provides a new way to use it, as follows

Download JAR Package

Address: github.com/pengzhile/ja-netfilter/releases

Writing configuration files

Specify your own directory to create this file: janf_config.txt, best practice is to just put the Jar package and this file in the same directory, do not have to specify this file twice

#janf_config.txt config file for jb [DNS]EQUAL,jetbrains.com[URL]PREFIX,https://account.jetbrains.com/lservice/rpc/validateKey.action-javaagent config

-javaagent:/your directory/ja-netfilter.jar

Complete Configuration Example

If you can open IDEA, find the following configuration

Add the last line: -javagent:/your directory/ja-netfilter.jar

If you can't open IDEA, try the following

Just now I have been messing around and looking at the project clone provided by the author to local debugging.

Found that just putting the configuration file and JAR file together causes the configuration file not to be read, as follows

Then I tested adding parameters to the command line-javaagent:/Users/user/IdeaProjects/ja-netfilter/target/ja-netfilter.jar= /Users/user/idea-agent/janf_config. txt

The results were as follows:
