`answer build --output` with relative path doesn't work

[davispuh]

Describe the bug

Using answer build --output name option binary is not actually created.

To Reproduce

Download and unpack https://github.com/apache/answer/releases/download/v1.4.2/apache-answer-1.4.2-bin-linux-amd64.tar.gz

$ ./answer build --output myanswer --with github.com/apache/answer-plugins/connector-basic
try to build a new answer with plugins:
[...]
[go build -ldflags -X github.com/apache/answer/cmd.Version=1.4.2 -X github.com/apache/answer/cmd.Revision=0fd7e81 -X github.com/apache/answer/cmd.Time=2025-02-06T08:31:57Z -o myanswer .]
build new answer successfully myanswer
$ ls -la
// there is no `myanswer`

If I don't specify --output parameter or if I specify full path --output /tmp/myanswer then it works.

Expected behavior

myanswer to exist

Platform

• Device: Desktop
• OS: Arch Linux
• Browser and version: N/A

Let me explain it. When build new answer with plugin, it will create a dir firstly, such like answer_build1980106637. All following command will be execute in this temp dir. So if you use the relative path, such as ./new_answer, the new binary will be put to answer_build1980106637/new_answer. After building the temp dir will be removed, so the binary will be clean too. In order not to cause misunderstanding, it is better to use the absolute path directly to ensure the correct output of the product.

BTW, A simpler way is as follows

./answer build --output ${PWD}/new_answer

That's totally unintuitive, no one would use absolute path without knowing about this issue. At first I thought that --output didn't work at all and only later I realized it works with absolute path.
So I would say that's just workaround to this issue.

I created a PR for this. Feel free to let me know if it's by design and I can close that PR.
