Gitlab CI runner 如何知道构建失败

Question

CI runner - Ubuntu
Executor - shell

somebody just asked me
How could the Gitlab CI runner knows the build failed ?

I mean
like my java project, sometimes the CI runner failed caused by compile error.
But how did the runner know there was an error happened ?

Is that because runner caught some exception from the shell ?

thanks

我想.gitlab-ci.yml脚本中的 build 命令返回的退出状态不是零。
