why execute script in codeql workflow like that way

[taojintianxia]

hi dear community, I was reading the codeql workflow and I found following script makes me curious

- run: ./mvnw -q -Dmaven.test.skip=true clean install || ./mvnw -q -Dmaven.test.skip=true clean install

what does this script mean ? why not just run one command ?

@taojintianxia Not sure but I guess it's meant for a redundancy for flaky builds. IDK if its still relevant.

Bingo, xxx || xxx retries the command xxx it fails. I guess it can be removed as the build looks to be stable for a long time, but leaving it as is does no harm tho.
