Answer 1

I guess I replied to your question on answers.atlassian.com and here the answer will be the same: https://maven.atlassian.com is not trusted by your Java.
Here is what you need to make ti trusted:
Download the certificate manually
This depends on what browser you are using. For IE7, you need to browse to the website (eg. https://maven.atlassian.com) then:
Right click on the page and access its Properties menu
Click on the Certificates button
Click on the Details Tab
Choose Copy to File
You will be taken to the Certificate Export Wizard, click next
Choose a format of the certificate that you would like to choose then
save the certificate to a directory of your choice.
Install the certificate to your keystore
You can use Java's keytool command to import it to your keystore, for example:
keytool -import -file myCertificate.cer -keystore myKeystor
