I couldn't find any solution for this problem after searching a lot.

This is the output of my java -version :

openjdk version "1.8.0_91"
OpenJDK Runtime Environment (build 1.8.0_91-8u91-b14-2-b14)
OpenJDK 64-Bit Server VM (build 25.91-b14, mixed mode)

Please help!

Answer 1

I had a similar situation, and fixed it by creating an environment variable called http_proxy and setting it to a meaningful value.

Fresh environment, but failed:

$ ~/Downloads/eclipse-installer/eclipse-inst

Fresh environment, but worked (I fired up Fiddler as a proxy):

$ export http_proxy=127.0.0.1:8888
$ ~/Downloads/eclipse-installer/eclipse-inst

I noticed that the proxy was never used, but simply checked for existence.
