why my jar build by gradle is not visible in another terminal?

Question

i got the following problem :

in a terminal linux #1, i do something like :

`

./gradlew clean 
./gradlew build

in a terminal linux #2, if i list files like..

cd my-gradle/build/libs
ls -al

i can't see the jar which has been created.

but if i do..

cd my-gradle/build/libs
cd ..
cd libs
ls -al

then i can see the jar. what is that ? !!!!

what i want is of course, getting my jar listed in my terminal #2 when i build it in a termninal #1

any propositions ?
