Get a whole compile_commands.json(which is used in cland and sonarlint) file with `catkin_make_isolated` of ROS. You also need to add this option `-DCMAKE_EXPORT_COMPILE_COMMANDS=1` when you run `catkin_make_islodated`

create_compile_commands.sh

#! /bin/bash

# Merge`build_isolated/*/compile_commands.json` to `build/compile_commands.json`

output_file="build/compile_commands.json"

rm -f "$output_file"

echo "[" > "$output_file"

first_file=true
for file in build_isolated/*/compile_commands.json; do
    if [ -f "$file" ]; then
        if [ "$first_file" = false ]; then
            echo "," >> "$output_file"
        fi
        
        sed -n '/\[/,/\]/p' "$file" | sed '1d;$d' >> "$output_file"
        echo "Merged $file into $output_file"
        
        first_file=false
    fi
done

echo "]" >> "$output_file"

echo "Merge process completed."
