Add a Quarkus integration to allow running in the JVM and Native mode

[soberich]

Description

There is a repo with reproducer.

Actual behavior

dumps NPE short stacktrace to stdout

Caused by: java.lang.NullPointerException

Steps to reproduce

This commit https://github.com/soberich/marvel/commit/66e29c94071b75345b132b453c092a12575e8b0f

on this branch bigfix/blaze-fails-to-integate-with-hibernate shows how I added blaze to try it out with quarkus.

git clone -b bigfix/blaze-fails-to-integate-with-hibernate git@github.com:soberich/marvel.git;
cd marvel;
./gradlew quarkusDev -S

On startup there would be an exception.

Environment

Version: [1.3.2,1.4.1) JPA-Provider: Hibernate 5.4 DBMS: H2
Application Server: Netty/Undertow

@soberich I am receiving the following error when I run your project with gradlew.bat quarkusDev -S on Windows:

Caused by: org.gradle.internal.resolve.ArtifactNotFoundException: Could not find guice-no_aop.jar (com.google.inject:guice:4.2.0).
Searched in the following locations:
    file:/C:/Users/<User>.m2/repository/com/google/inject/guice/4.2.0/guice-4.2.0-no_aop.jar

The directory only contains guice-4.2.0.jar.

@Mobe91 This is funny because makes no sense for me. What does it have to do with Guice? this project have nothing to do with Guice. I see exception pointing to internals of Gradle which is even more confusing, and also, I rarely use local artefacts repos. Project lists a lot of repositories to lookup for dependencies, so it can get them in as many places as possible as it is a playground. Please try to check these:

1. Are you sure you are in the right folder?
2. Are you using firewall, proxy which can limit web-access?
3. Are there any Gradle specific company-wise or machine wise properties applied (e.g. in ~/.gradle/...properties
4. Are you sure you are not supplying implicitly some flags like --offline or something with similar semantics to make gradle only resolve in restricted manner.

Last two are most viable candidates. Hope I am already too late and you have figured out what was wrong. Please, let me know @Mobe91 thank you.

EDIT: As you see above I mentioned your comment in commit where I removed any bounds from mavenLocal() which is just to try, though I am 100% sure it is not the case, but just to take some action on your comment.

Below I provide as full stacktrace as I could get. The error in question, unfortunately prints to stdout in quite, so it is still trimmed no matter what.

An NPE at line 58 indicates that the Database service binding is not available. Missing services indicate a classpath problem. Java's Service Provider mechanism is described in for example this blogpost. The services are usually registered through resource files in META-INF/services/. Recently I stumbled upon a very similar issue myself, when I was creating a WildFly module for Blaze-Persist (documented on Slack). I don't know how Quarkus works, but I suppose it creates some sort of special classpath where services from libraries are hidden, or the Service Provider API is not available at all. From a simple Google search I cannot easily find examples of the Service Provider API within Quarkus.

One thing that you might want to try is to copy the contents of the META-INF/services folder of the jar dependencies to your applications META-INF/services folder.

This should at least contain the files:

com.blazebit.persistence.integration.hibernate.base.HibernateAccess
com.blazebit.persistence.spi.EntityManagerFactoryIntegrator
org.hibernate.boot.spi.MetadataContributor
org.hibernate.integrator.spi.Integrator
org.hibernate.persister.spi.PersisterClassResolver
org.hibernate.service.spi.ServiceContributor

(these are the ones from blaze-persistence-integration-hibernate-5.3:1.3.2, but the other jars probably have services too)

[jwgmeligmeyling]

@soberich were my remarks any useful?

[soberich]

@JWGmeligMeyling yes. It should be something about writing extension https://quarkus.io/guides/extension-authors-guide But does library considers that kind of support? There are some frameworks like Micronaut, Quarkus etc, which would be really nice to have.

[beikov]

At this time, I do not anticipate to work on this as there are other features I consider more important. At some point I will look into this, but the hibernate integration and entity views relies heavily on reflection, so I guess it will be a lot of work to get Blaze-Persistence fully running with Quarkus. If anyone wants to work on this, I can help with explaining what is necessary or provide guidance.

[soberich]

@beikov @JWGmeligMeyling I have raised a feature-request there as you see. Let's leave this open.

[Mobe91]

In case anyone stumbles over the issues I had with running the demo project: This is a gradle issue.

You need to delete the parent directory of the guice dependency in your local maven repository, otherwise gradle won't attempt to download the no_aop version of the dependency, i.e. delete ~/.m2/repository/com/google/inject/guice/4.2.0 and then it should work.

And you need to run it with JDK8.
