Work logs, certificates invalid unable to find valid certification path to requested target

This problem was recently made a large head. Cause all uses se.transmode.gradle:gradle-docker:1.2of all projects can not start! I do not know why this is so, but other colleagues of the project can be properly packaged to run! Spent a lot of half-time finally toss well.

abnormal situation:

Exception log:

Solutions

Internet to find some solutions are added to the local post-export certificate. First I encountered this problem and did not know where to export the certificate. Log in to see the prompt Failed to list versions for com.github.jnr:jffi.. I began to suspect that is because the certificate error caused the failure, so maven repository will jffibe imported and added to the local certificate, restart IDEA, failed. Moment, confused. I began to try to import the certificate to other URLs; try another gradle docker plugin; even restart the computer use both methods. Toss for a long time, the result ended in failure.

And finally re-read it again log se.transmode.gradle:gradle-docker:1.2 > com.github.docker-java:docker-java:0.9.0 > com.github.jnr:jnr-unixsocket:0.3 > com.github.jnr:jnr-ffi:1.0.3holding a try of the mentality of try to import the jnr-ffi:1.0.3certificate, the result is successful, the mentality jumped. He jumped. A.

Specific steps

The first step: analysis of the log that lists the suspect jar certificate becomes invalid.

Step two: enter maven repository (possibly PW), find the corresponding jar page.

The third step: to export the certificate to a local

Step four: Open cmd window as an administrator, execute ./keytool -import -alias 别名 -keystore cacerts -file 证书地址the command to add certificate, suggesting that "the certificate has been added to keystore" button.

Step five: Restart IDEA

If one did not succeed, you can put other suspect objects are added.
