Does java buildpacks will download jre everytime?

[SummerLatte]

Hi:
I often use command like this to build image.
mvn clean package
pack build icede-demo-java --path target/*.jar --buildpack gcr.io/paketo-buildpacks/java --builder paketobuildpacks/builder:base --env BP_JVM_VERSION=17
When i modify my code and decide to build a new image, I notice command output will contain "Downloading from https://github.com/bell-sw/Liberica/releases/download/17.0.7+7/bellsoft-jre17.0.7+7-linux-amd64.tar.gz
". It seems like buildpacks will download jre everytime.

Is that true? If so, is there any chance to avoid download jre everytime?

Best Regards

Hard to say if it is true or not for your particular case without more information, but generally speaking, it should not download every time. If it does, then something is not working properly.

To expand, there are things you can do which will make it download every time. For example, changing the name of your application image or appending a unique build number to the name of your application image, or clearing out the cache.

Anyway, if you are seeing it download on every build, feel free to post your build logs and we can look at why it is doing that.

Hi dmikusa:
Thank you for reply. Here is my full log.

So I see things like Launch Helper: Reusing cached layer which indicate that buildpack layer level caching is happening. This is the primary way that the buildpack caches and prevents downloads from happening over and over. That said, it's not happening for your JVM.

BellSoft Liberica JRE 17.0.7: Contributing to layer

It says Contributing to layer so it either a.) doesn't see the previously cached data or b.) it thinks that cached data has changed and that it needs to fetch it again.

Please run one more build and include the -v -e BP_DEBUG=true arguments to your pack build command. That will output a whole bunch of additional information. Attach that here and I can take a closer look. It should show more details on what is happening.

Hi dmikusa:
It's quite a long log. Can't reply all of it. I cut out part of it. Hoping it contains the information you are looking for.
Best Regards

OK, it looks like there is some difference between the expected/actual metadata. It is probably a known issue where the deprecation date can cause problems. Fortunately, there is a fix for this in the latest libpak (1.66.0), and we're rolling that out here shortly (hopefully by the end of this week).

I would suggest trying again with the latest buildpacks next week, and then please report back on how that went. If it's not it, we can look at other options.
