   As far as I remember, the Embedded C/C++ Eclipse plug-ins do not deal with ssh, I guess the issue is in Eclipse core.

   Unable to negotiate with x.x.x.x port 48694: no matching key exchange method found. Their offer: diffie-hellman-group1-sha1,diffie-hellman-group14-s]

   Above algorithms are used in com.jcraft.jsch_0.1.55.v20230916-1400.jar but same alog's are not supported in sshd10.3
   now how can i update this plugin in eclipse ?

   or is there any plan updating eclipse with jsch-0.2.21.jar plugin which supports algorithms which are present in sshd 10.3 ?

   Can you point where exactly in the Embed CDT plug-ins is this jar used?

   Ok, but what makes you think that they have anything to do with Embed CDT plug-ins?
