Recently, when I was developing a strategy with NetBeasIDE, I got the following error when compiling:
[INFO] -------------------------------- [ jar ]---------------------------------

Hello,

Please note that a month ago we updated SDK version, so make sure you have up to date one set up in your IDE. You can download new version here: https://www.dukascopy.com/wiki/en/devel ... jforex-sdk

settings.xml is not required.

It will be enough pom.xml and I attached file to this email.
Also I recommend you to try other solutions from stackoverflow if this settings do not work for you.

Please also note that you need to choose Java 8 in settings of your IDE too.
Personally I always used, Inteliji IDEA and did not face any issues with set up, but still we do not advise this or another application. Its up to you.
Hope it helps!

Yours sincerely,
