I posted this question to Developers forum without any reply. So, I posted here to see if anyone could point me to a solution.
I tried to import GN 2.10.3 into Eclipse. At the step "Setup Maven Plugin connectors", I encountered an error "yuicompressor-maven-plugin:0.9:compress (1 error)" (with "Action" Resolve Later). The error description shows "No marketplace entries found to handle yuicompressor-maven-plugin:0.9:compress in Eclipse. Please see Help for more information.".
Went to "Help" --> "Eclipse Marketplace", and did not find any "yuicompressor-maven-plugin". Though I found "Yui compressor" and installed it as a plugin, but did not solve the problem.
So, How to resolve this issue?
By the way, I use "Eclipse Luna RC3 Release" on a Linux box.
Thank you very much.
