Programatic way to check if a property is build time

[shawkins]

Keycloak for several reasons captures whether a given option is build time or not - however after adding some stricter logic about the handling of build time properties we've noticed several of our options were marked incorrectly as run time. If we have a set of quarkus property names, is there a way that we can programatically check which ones are build time?

see keycloak/keycloak#26175

There is nothing ready made OOTB, but it is theoretically possible (a good idea of how it could be done it follow the logic of how Quarkus warns about a build time property being overridden at runtime).

In any case, cc @radcortez

Yes, it is possible.

Check

quarkus/core/deployment/src/main/java/io/quarkus/deployment/builditem/ConfigurationBuildItem.java

Line 10 in 9dd3919

private final BuildTimeConfigurationReader.ReadResult readResult;

And then:

quarkus/core/deployment/src/main/java/io/quarkus/deployment/configuration/BuildTimeConfigurationReader.java

Line 1221 in 6053da3

public Map<String, String> getAllBuildTimeValues() {

Thank you @radcortez let me see how far I can get with that.
