Maven cannot download the dependent jar whose warehouse address is https, and the configuration parameters ignore the SSL security check.

problem causes

The address used by the private server https, and the security certificate has expired or does not exist. When using the maven command, you can add the following parameters to ignore the security check.

mvn -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true -Dmaven.wagon.http.ssl.ignore.validity.dates=true

Detailed explanation of parameters

• Dmaven.wagon.http.ssl.insecure=true- Allow relaxing ssl security checks;
• Dmaven.wagon.http.ssl.allowall=true- Allow all X.509 format certificates to match. If changed to false, the same check as the browser will be performed;
• Dmaven.wagon.http.ssl.ignore.validity.dates=true- Ignore certificate expiration issues

idea configuration default parameters

Configure VM options in idea, and then you can use these parameters by default

Maven configures the setting so that it ignores security checks
