问题
I'm using Ubuntu 12.04, and to install Eclipse Juno I downloaded it from the official site (I don't use apt-get nor software center)
After updating it from help > check for updates menu, my Eclipse cannot make new project. When I hover File > New, there isn't any menu to select (as the usual Java Project, C++ Project etc.), only an unselectable text like this:
< No Applicable Items >
Anyone know what causes this?

nitind's answer above helped solve my problem. I was using eclipse java ide juno on windows and i could not see any items under File -> New or under Window -> Show View. I noticed eclipse had defaulted to using the Java-EE perspective. Following nitind's suggestion I changed it to the Java perspective and can now see all the menu items. thank you!

I had the same error when i first started the program, but i looked into it, and I saw that the workspace already had .cpp and compiled files in it which i had compiled earlier with a different program. To fix the error, I just changed the workspace to the default, and it worked fine.
I was using eclipse CDT Kepler with java 1.6.0_27. I then tried it with java 1.7.0_25 and eclipse Juno and this method resolved the error in any of these instances.
Try using the default workspace and it should work.
