Dukascopy Support Board • View topic - Custom plugins with @Library() got broken in 3.2.9

mtnfx

After recent automatic update of JForex to 3.2.9 i'm not able to use my plugin with annotation @Library("external.jar").

I notice 2 problems there (from JForex\logs\*.log):

1. If a class with plugin code already appears in "external.jar" i receive that error
(note: NO error messages are displayed in UI - i just silently not able nor open MyPlugin.java nor activate plugin compiled earlier)

2. After fixing problem #1 (i.e. removed MyPlugin.class from "external.jar"), i'm able to compile it, but plugin fails to start - it seems that class loader does not see classes from "external.jar" (the 'stub/IAccountStub' mentioned below)

Please fix this ASAP because plugins became not usable

To access, I had to delete all the jfx files that use the libraries from the Strategies folder, but then they can not compile them.

With the previous version everything worked properly, can you check it out?

Thank you.

Thank you for having restored the 3.2.6 version, now everything works.
