/tmp/jenkins7873117652666079835.sh: line 6: la: command not found

Commands which I gave in command shell
#!/bin/bash
java -version
ls -al
rm -rf *.war
./build.sh
la -al

Facing something like this now where the command la "can't be found" if it is used inside $(...) while in a Bash script, but ls -al works. Both work just fine in shell (with and without $(...)).
