Prepare for the removal of artifacts directories next

[JohnNiang]

I removed artifacts/m2 folder according to this instruction: https://docs.github.com/en/github/authenticating-to-github/removing-sensitive-data-from-a-repository.

This PR is aimed to prepare for the removal of artifacts directories next.

What needs to be noted here is what needs to be done after the merge:

1. Clone devops-java-sample with mirror flag.

git clone --mirror [email protected]:kubesphere/devops-java-sample.git

2. Download https://repo1.maven.org/maven2/com/madgag/bfg/1.14.0/bfg-1.14.0.jar

wget -c https://repo1.maven.org/maven2/com/madgag/bfg/1.14.0/bfg-1.14.0.jar -P ~/Downloads

3. Go into devops-java-sample repo
4. Delete artifacts folder

java -jar ~/Downloads/bfg-1.14.0.jar --delete-folders artifacts --delete-files artifacts --no-blob-protection .

5. Garbage collection

git reflog expire --expire=now --all && git gc --prune=now --aggressive

6. Push and update all refs on remote server

git push

I left some comments. And please fix the conflicts.

[LinuxSuRen]

Why using wildcards here?

[LinuxSuRen]

I'd recommend that providing some description about the purpose of this file here.

[LinuxSuRen]

Where does the base image harbor.devops.kubesphere.local:30280/library/java:openjdk-8-jre-alpine comes from?

[JohnNiang]

I think we should make a tutorial about devops hand's lab in offline mode.

[LinuxSuRen]

Why using wildcards here?

[JohnNiang]

Cause we couldn't know the specific jar name directly. If you have any better suggestions, you can come up with them.

[JohnNiang]

Thanks for your review. I'll fix them as soon as possible.

[LinuxSuRen]

There're too many people who are creating PRs for test purposes. I'm going to close all PRs. And try to disable the PR feature.

And we can maintain the sample project in another ways.
