I have followed the https://helpx.adobe.com/experience-manager/using/aem63_htl_youtube.html#SetupMaveninyourdevelopmente...
I have followed the same steps it is working file
but now is how i can get the logs for the same component which i developed.
you may check error.log of AEM server, search for the package/class name of java code.
for sightly logs - AEM-Tools/sightly-log-filter at master · SixDimensions/AEM-Tools · GitHub
HTL - Sightly console log filter · GitHub
If you have a Java part of your component - you an setup a log by following this article. T His is very handy as it allows you log out messages from a given Java package:
Creating a custom log file for an Adobe Experience Manager project
So you can map a custom log file to com.aem.community.core.
Hope this helps...
PS -- we will update this article to AEM 6.4 soon.
