An SSL handshake problem happens when SSL is forced in one of the ends, in an environment where SSL was not configured.
ソリューション
A way to avoid this problem is by telling Bamboo to not use SSL explicitly. To do this:
- Stop Bamboo.
Edit the
<bamboo_home>/bamboo.cfg.xmlfile and look for the following line:<property name="hibernate.connection.url">YOUR_DB_URL</property>Add the "
useSSL=false" flag so it looks like this:<property name="hibernate.connection.url">YOUR_DB_URL?useSSL=false</property>
If you have more than one parameter, separate them with a semicolon.- Start Bamboo again.
