Introduce --link-at-build-time flag for GraalVM 22.1 and later #24213
Conversation
oracle/graal#4305 makes `--allow-incomplete-classpath` the default behavior (removing the flag) and introduces a new flag `--link-at-build-time` which enables us to set which classes/packages we require to be resolvable at build time. Passing `--link-at-build-time` without arguments to `native-image` requires all classes/packages to be resolvable at build time, essentially bringing the pre-22.1 behavior back.

No please don't enable it "blanket": it will break some extensions, such as the oracle JDBC driver.
The global enablement flag needs to take into account exceptions; I suspect a new build item needs to be introduced to control the flag explicitly on each jar.
It is not enabled "blanket", it is disabled if any
That would be an optimization. This PR aims to reproduce the current behavior with 22.1 and later while also avoiding getting warnings. |

oh, missed that! sorry - my mind is elsewhere as I'm actually on PTO but this PR got my attention :) Many thanks @zakkak :) |
