Dear colleagues -
If you've updated to Java 11 and would like to get rid of the error messages you get from maven 3.6.0 during a build, then it may be time to upgrade to
maven 3.6.3. Most of the error messages you have been seeing will go away. If the maven upgrade is too complicated, then don't worry about it, the error messages seem harmless enough.
We plan to deploy the updated 1.7.0-SNAPSHOT the week of 9 December, and we plan to release 1.7.0 in late January or early February. These versions require Java 11, and the 2020 tournament will be run with 1.7.x. So it's time to get your Java environment updated and make sure you can run the updated server and that your broker works in this environment. If you encounter difficulties, please don't hesitate to ask for help.
Best of luck in the upcoming tournament -
John
