tar: .: file changed as we read

https://stackoverflow.com/questions/20318852/tar-file-changed-as-we-read-it

因为压缩过程中压缩文件已经创建，压缩当前目录会包含压缩文件自己，导致了这个警告

解决方法1

mkdir artefacts
tar -zcvf artefacts/archive.tar.gz --exclude=./artefacts .
echo $?
0

解决方法2

touch archive.tar.gz
tar --exclude=archive.tar.gz -zcvf archive.tar.gz .
echo $?
0
