"JDK_1.8" platform could not be found

Question

I searched on google and found this :
https://stackoverflow.com/questions/16887253/netbeans-broken-platform

platform.active=default_platform
platforms.default_platform.home=${java.home}/../

I replace :
platform.active=JDK_1.8

I changed the text to be like this :
platform.active=default_platform

I don't understand what this means:
platforms.default_platform.home=${java.home}/../

Do I have to add that text under platform.active=default_platform ?

I don't understand the meaning of /. . / What should I write there?

Answer 1

Having /../ in the path indicates that the next location in the hierarchy is relatively up one level from the current folder. In other words, the folder is one level back (or up) from wherever the environment variable ${java.home} points to. It is a way to navigate to the folder that contains ${java.home} without knowing where it is.
