Migration Guide 1.8

Datasource configuration

This is the last call to migrate your deprecated datasource configuration to the new one before it gets removed in Quarkus 1.9 - the new datasource configuration was introduced in Quarkus 1.3.

So if you are still using quarkus.datasource.url or quarkus.datasource.driver, please refer to the datasource guide to migrate your configuration.

Hibernate ORM

If you are using a persistence.xml to define your persistence units and want to enable entity class scanning, you need to add:

<property name="hibernate.archive.autodetection" value="class" />

to your persistence.xml.

Quartz

The configuration for Quartz extension points (job listeners, trigger listeners, plugins) has changed.

If you are using this advanced feature, please refer to the updated Quarz configuration reference to migrate your existing configuration.

Hibernate Search + Elasticsearch (Preview)

• Configuration properties for index defaults can no longer include the .index-defaults component. For example, quarkus.hibernate-search.elasticsearch.index-defaults.schema-management.required-status should now be written simply as quarkus.hibernate-search.elasticsearch.schema-management.required-status.
• query.explain() now expects to be passed an entity ID instead of a document ID. In short, if your entity has an ID of type Long, you need to pass a Long (previously you had to pass a String).
• @IndexedEmbedded.storage/ObjectFieldStorage have been renamed to @IndexedEmbedded.structure/ObjectStructure. The older syntax is deprecated and will eventually be removed.
• quarkus.hibernate-search.elasticsearch.default-backend no longer exists. You can either configure a default backend (quarkus.hibernate-search.elasticsearch.someProperty someValue) or named backends (quarkus.hibernate-search.elasticsearch.backends."backend-name".someProperty someValue), but a named backend can no longer be considered as the default backend.

Kubernetes Config

• When setting quarkus.kubernetes-config.secrets.enabled=true, it is now no longer necessary to also set quarkus.kubernetes-config.enabled=true in order to read Secrets.

Jib

• The quarkus-container-image-jib extension no longer sets the quarkus.http.host System Property to 0.0.0.0 because Quarkus defaults to 0.0.0.0 (which has been the case for a very long time). This change means that if quarkus.http.host is set in application.properties, then the container image created by Jib will honor the value - as opposed the previous behavior, which was that value being overriden by the quarkus.http.host System Property.
