fatal: 'webrtmt' does not appear to be a git repository could not read from remote

Question

I have the below shell script named as fetchGitRepo.sh :

#!/bin/bash

if [ -z $1 ]; then
        echo "Missing first argument (git repository path)"
        exit 1
fi
arg=$1
CHECKOUT_DIR=$(pwd)/$arg
BASE_DIR=$(pwd)
set -euo pipefail
basename=${1##*/}

if [[ $# -lt 1 ]]; then
    printf '%s: Clone the latest tag on remote.\n' "$basename" >&2
    printf 'Usage: %s [other args] <remote>\n' "$basename" >&2
    exit 1
fi
remote=${*: -1} # Get last argument
echo BASE_DIR: $(pwd)
echo $CHECKOUT_DIR
if [ "$arg" == "webrtmt" ]; then
        echo $arg >> ${arg}.txt

 gradle -Pproduction=true build
else
        make all

fi

when I run this file passing webrtmt as the parameter like this ./fetchGitRepo.sh webrtmt , I get the below error:

Please help on how to fix this. Thanks

Answer 1

From the script in the question, when you run ./fetchGitRepo.sh webrtmt , there are some problems.

remote=${*: -1} # Get last argument

Here remote is assigned the value webrtmt . And then it's used in git ls-remote --tags --exit-code --refs $remote . It's okay to use git ls-remote outside of a git repository, but a valid url is needed. Here $remote is webrtmt . It's an unknown remote and it's not a valid url either. So git ls-remote complains and raises the fatal error.

I think it should be git ls-remote --tags --exit-code --refs $GITREPO instead. The pipeline commands retrieve the expected tags.

ls -l ${GITREPO} &> /dev/null

However, then this command is odd. ${GITREPO} is a url in ssh protocol to a remote repository, and we cannot use ls on it.

I'm afraid you don't pass the right parameters to the script, or the script needs modification.
