DS 1.4 mysterious case on deploying component

Hello,

i try to create a new SDK Extension, see Chapter 3.2 in Dev Guide.

the deployment of the colored box was successfull, i created a Feature .zip and installed it on DS.

Now, i got a problem with the copy of the project, sample Company box, it don´t appear in DS after installtion. I deployed it the same way.

I checked all strings 5 times, no errors or warnings. I created new copies and also checked the strings, same problem.

all .jar files are on the right place.

Has anybody the same mysterious case???

my config:

win8.1 64bit

eclipse Luna 64bit

jre 1.7.0.75
