How to delete intermediate shared artifacts in Bamboo?

[Tarun Sachdeva]

We generate certain artifacts in the initial code checkout stage of the build process (compiler fetch from git) and these are used for further stages. Since, they are shared artifacts used in the next stages, we have to add them as artifacts in the initial code checkout stage. 

After the build process is over, we do not wish to retain these intermediate shared artifacts from the initial stage. Is there any way to delete them in the final stage?

If not, then is it possible to manually delete these artifacts selectively from UI/API? Right now, selective artifacts deletion is not possible for a build in UI. All artifacts get deleted together.

As a "workaround" you could create a ScriptTask and delete those artifacts by shell command. Surely not the answer you are looking for, sorry ;)

I don't think deletion of the shared artifacts on bamboo server via some shell/script is a good idea, considering that it is possible to identify the path of the shared artifact. 

As per an old post, it appears there is no way to delete the shared artifacts.

One should know the path of the artifact, since it is defined along with the artifact. It is then stored inside the <bamboo-home>/xml-data/build-dir/<JobKey> folder, where JobKey is the key of the Job where the artifact is used (ArtifactSubsription). But I don't know, if it is a good idea to delete the file on the file system, while bamboo holds a link in the Stage>Artifacts View
