i using jenkins on both windows local machine , ubuntu server

contents of shell script :

echo 'asklytics-commons-test: cleaning ...' ./gradlew clean || { echo 'gradlew clean --refresh-dependencies failed!!' ; exit 1; }  echo 'asklytics-commons-test: building ...' ./gradlew build || { echo 'gradlew building failed!!' ; exit 1; }  echo 'asklytics-commons-test: jarring...' ./gradlew jar || { echo 'gradlew jarring failed!!' ; exit 1; }  echo 'asklytics-commons-test: publishing ...' ./gradlew publish || { echo 'gradlew publish failed!!' ; exit 1; } 

the shebang line must first thing in file. since use bash features, first line of file must be

#!/bin/bash or #!/usr/bin/env bash.
