HowTo BUILD jar?

Failed within local: ./gradle build
java -jar build/libs/ModeratorElection.jar -> localhost:6333 "White Label..."-Error

=> ./gradlew clean build -Pvaadin.productionMode
..in ide dev: ./gradlew clean vaadinPrepareFrontend

-x processTestAot - exclude, skip tests

https://docs.spring.io/spring-boot/gradle-plugin/aot.html
Processing Tests
The AOT engine can be applied to JUnit 5 tests that use Spring’s Test Context Framework. 
Suitable tests are processed by the 'processTestAot' task to generate 
'ApplicationContextInitializer' code. As with application AOT processing, the 'BeanFactory' 
is fully prepared at build-time. As with 'processAot', the 'processTestAot' task is 'JavaExec' 
subclass and can be configured as needed to influence this processing.
The 'nativeTest' task of the GraalVM Native Image plugin is automatically configured to 
use the output of the 'processAot' and 'processTestAot' tasks.

For production:
* install.sh 
    git clone --single-branch --branch main https://repo.prod.meissa.de/meissa/ModeratorElection.git /usr/local/src/ModeratorElection
     

build graalvm binary
1. First build jar locally, and get META-INF with   
    ./gradlew clean build -Pvaadin.productionMode -x processTestAot
    MEMBERNAMES=er,sie,es java -agentlib:native-image-agent=config-output-dir=src/main/resources/META-INF/native-image -jar build/libs/ModeratorElection-0.0.1-SNAPSHOT.jar 
    curl -X GET localhost:8080 
2. graalvm native-image compilation
    ./gradlew nativeCompile -Dvaadin.productionMode=true //-H:ConfigurationFileDirectories=/path/to/config-dir/ notwendig falls nicht in src/main/resources/META-INF/native-image/

vaadin 24.3.3, after npm audit fix during image build: 
npm warn deprecated workbox-google-analytics@7.0.0: It is not compatible with newer versions of GA starting with v4, as long as you are using GAv3 it should be ok, but the package is not longer being maintained  
npm warn deprecated sourcemap-codec@1.4.8: Please use @jridgewell/sourcemap-codec instead  
npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.  
npm warn deprecated rollup-plugin-terser@7.0.2: This package has been deprecated and is no longer maintained. Please use @rollup/plugin-terser  
npm warn deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported
