Use generic cachi2 artifact paths in konflux.Dockerfile

[fbladilo]

Summary

• Update konflux.Dockerfile to copy cachi2 artifacts using stable generic filenames, matching the existing release-0.9 / MTA 8.1 pattern
• Version-specific URLs remain in ocp-build-data artifact lockfile entries; only the lockfile filename field and Dockerfile cp paths stay constant

Motivation

main currently hard-codes versioned cachi2 paths (e.g. jdt-language-server-1.51.0-...tar.gz), so every JDTLS or Maven coord bump requires a Dockerfile change. The 1.51.0 Eclipse milestone was also removed, breaking prefetch/rebase.

MTA 8.1 already uses generic lockfile filenames (ocp-build-data mta-8.1) and generic cp paths on release-0.9. MTA 8.2 ocp-build-data is aligned in openshift-eng/ocp-build-data#11596.

Changes

cachi2 path (before)	cachi2 path (after)
fernflower-8.1.0.GA-redhat-00001.jar	fernflower.jar
java-analyzer-bundle.core-8.1.0.CR1-redhat-00003.jar	java-analyzer-bundle.core.jar
maven-index-data-v20251112021242.zip	maven-index-data.zip
jdt-language-server-1.51.0-202510022025.tar.gz	jdtls-product.tar.gz

Test plan

• Merge with ocp-build-data mta-8.2 artifact lockfile generic filenames
• Jenkins layered-products rebuild: mta-jdtls-server-base, mta-java-external-provider, mta-cli

Summary by CodeRabbit

• Bug Fixes
  • Updated the build to use standardized artifact names during packaging, helping ensure the correct files are picked up reliably.
  • Kept the existing extraction and placement behavior intact while aligning it with the newer artifact naming format.

📝 Walkthrough

Walkthrough

Updated konflux.Dockerfile to reference generic artifact filenames (fernflower.jar, java-analyzer-bundle.core.jar, maven-index-data.zip, jdtls-product.tar.gz) copied from cachi2 output paths, replacing previous version-specific filenames. Unpacking and copy logic remains unchanged.

Changes

Generic Artifact Filename Update

Layer / File(s)	Summary
Generic filename substitution for build artifacts konflux.Dockerfile	Source filenames for fernflower, java-analyzer-bundle, maven-index-data, and jdtls artifacts are updated to generic names copied from the cachi2 generic output paths, with existing unpack/copy flows unchanged.
