SSL sync error

[edmundlaugasson]

used latest 0.0.3 version of mnIMAPSync with different Java versions OpenJDK 17; Oracle JRE 17 and 8: java -jar mnIMAPSync.jar --host1 imap.gmail.com --port1 993 --user1 [email protected] --password1 password --ssl1 --host2 other.server.com --port2 993 --user2 [email protected] --password2 password2 --ssl2

Without SSL it starts but no sync follows and numbers remain as zero.

Error message:

SEVERE: null

Hello @edmundlaugasson ,

I compiled from source using gradle and seems that with newer version of JDKs doesn't work. It requires gradle < 7 and JDK 8 for build the project.

I m preparing a pull request for add a new functionality for extract the parameters for sync with a properties file.
