4.0.x build issues (for use with Java 17)

[volosied]

4.0.x requires a min of Java 11, but it doesn't build with it due to error:

[ERROR] Failed to execute goal io.quarkus:quarkus-maven-plugin:3.2.9.Final:build (default) on project quarkus-myfaces-showcase:
[ERROR] The plugin io.quarkus:quarkus-maven-plugin:3.2.9.Final has unmet prerequisites:
[ERROR] Required Java version 17 is not met by current version: 11.0.32

If I use Java 17, then I get:

[ERROR] Failed to execute goal org.apache.felix:maven-bundle-plugin:4.0.0:manifest (bundle-manifest) on project myfaces-api: Execution bundle-manifest of goal org.apache.felix:maven-bundle-plugin:4.0.0:manifest failed.: ConcurrentModificationException -> [Help 1]
[ERROR]

I've updated the dependencies to use Java 17 (but still have the source/target set to 11). Inadvertently, Java 17 caused number converter errors which I've also fixed.

[tandraschko]

Why the CI on 11 builds then sucessful?

[volosied]

API/ IMPl still use Java 11:

javap -v ./target/classes/jakarta/faces/convert/ShortConverter.class | grep major
major version: 55

javap -v ./target/classes/org/apache/myfaces/renderkit/html/base/HtmlMessageRendererBase.class | grep major
major version: 55

Quarkus Extension use 17:

javap -v ./quarkus/runtime/target/classes/org/apache/myfaces/core/extensions/quarkus/runtime/exception/QuarkusExceptionHandler.class | grep major
major version: 61

[volosied]

May not be needed anymore. I could remove.

[tandraschko]

CI is working on 11
Both Apache and GitHub

[volosied]

Don't understand what's going on....? I'm only running mvn clean install.

yeah 4.0 is Java 11 i thought 4.1 was 17?

[volosied]

CI runs mvn clean deploy -Pgenerate-assembly but not mvn clean install

Please try yourself. I'm not able to get it to run with Java 11.

Edit: CI must somehow switch to Java 17, I believe.

[tandraschko]

4.0 is Java 11
So please create a PR first to change the CI, so we see errors within CI

[melloware]

The CI for 4.0.x already runs as 11? See:

myfaces/.github/workflows/myfaces-ci.yml

Lines 57 to 64 in d7f25e5

	- uses: actions/checkout@v3
	with:
	persist-credentials: false
	- name: Set up JDK 11

[tandraschko]

I mean the mvn clean Install before the deploy?

[melloware]

OK added PR: #1060

[melloware]

OK confirmed it says Quarkus 3.2 supports JDK 11 but let me try 3.2.12 its the last version of 3.2.X

[melloware]

ahh it looks like 2.16.12.Final is the last Quarkus to support Java 11.

[melloware]

crap this looks like a bigger change than we want. @tandraschko should we just commetn out the Quarkus Extension in this 4.0.X branch? Or build with 17 which should set the MyFaces to 11 and allow Quarkus Extension to build with 17 fine?

[tandraschko]

No Idea
We have 3 Options:

• move to java17, spec is java 11
• release without quarkus
• move quarkus to a own project

[tandraschko]

TBH i would Release without quarkus, Just remove it from root pom. Quarkus user are more bleeding edge, they can just go to 4.1?!

[tandraschko]

Can you add it to your PR @melloware?

[melloware]

yep i totally agree @tandraschko fixing my PR now

[melloware]

@volosied all fixed! Closing this PR
