Command runs from terminal without error but fails from bash script

Below command runs without any error from terminal but fails from bash script.

/usr/local/go/bin/go build -o bin/adapter -ldflags="-X main.level=info" cmd/adapter/*

My bash script is as shown below :-

#!/bin/bash

export GO=/usr/local/go/bin/go
export ldflags="-ldflags=\"-X main.level=info\""

CMD="$GO build -o bin/adapter $ldflags cmd/adapter/*"
echo $CMD
${CMD}

Bash debug using "bash -x" produces following output :-

+ export GO=/usr/local/go/bin/go
+ GO=/usr/local/go/bin/go
+ export 'ldflags=-ldflags="-X main.level=info"'
+ ldflags='-ldflags="-X main.level=info"'
+ CMD='/usr/local/go/bin/go build -o bin/adapter -ldflags="-X main.level=info" cmd/adapter/*'
+ echo /usr/local/go/bin/go build -o bin/adapter '-ldflags="-X' 'main.level=info"' 'cmd/adapter/*'
/usr/local/go/bin/go build -o bin/adapter -ldflags="-X main.level=info" cmd/adapter/*
+ /usr/local/go/bin/go build -o bin/adapter '-ldflags="-X' 'main.level=info"' 'cmd/adapter/*'
invalid value "\"-X" for flag -ldflags: missing =<value> in <pattern>=<value>
usage: go build [-o output] [build flags] [packages]
Run 'go help build' for details.

Am I doing something wrong?

Until now I tried using different double quote(") escaping techniques also tried $ldflags and "$ldflags" but gets the same output.

Update 1 :-
Tried below option but still not working :-

ldflags=(-ldflags="-X main.level=info")
${ldflags[@]}

Debug output for above trial is as follow :-

+ mkdir -p bin
+ export GO=/usr/local/go/bin/go
+ GO=/usr/local/go/bin/go
+ ldflags=(-ldflags="-X main.level=info")
+ export ldflags
+ CMD='/usr/local/go/bin/go build -o bin/adapter -ldflags=-X main.level=info cmd/adapter/*'
+ echo /usr/local/go/bin/go build -o bin/adapter -ldflags=-X main.level=info 'cmd/adapter/*'
/usr/local/go/bin/go build -o bin/adapter -ldflags=-X main.level=info cmd/adapter/*
+ /usr/local/go/bin/go build -o bin/adapter -ldflags=-X main.level=info 'cmd/adapter/*'
malformed import path "main.level=info": invalid char '='
malformed import path "cmd/adapter/*": invalid char '*'

but fails from bash script ....

Your commands are not identical. In the first version (which you claim to work), you write

/usr/local/go/bin/go build -o bin/adapter -ldflags="-X main.level=info" cmd/adapter/*

which means that the 4th parameter to go (argv[4] in C-terminology) becomes (after the shell deals with the quotes)

> -ldflags=-X main.level=info

In your script, we can see from the trace that this parameter is pased as

> -ldflags="-X

which means that we have an undesired double quote, and main.level=info is missing (this goes into the next parameter).

I would in your case define the parameters in an array
the way go wants to see them, i.e.

pars=(build -o bin/adapter '-ldflags=-X main.level=info' cmd/adapter/*)

and run them like this:

echo Running $GO "${pars[@]}" ...
"$GO" "${pars[@]}"
