logback | SpringBootSpring Security基本配置 | Security library

Spring boot 2.6.1 supports logback 1.2.7

I've added the following dependencies in project

I'm making plugin for Minecraft - 'Paper' exactly. And it uses JDA for Discord bot function.

The problem is, Minecraft(Paper) uses log4j as its logging library. JDA uses slf4j as its logging library. I want JDA to use log4j so that error message of JDA would be shown in console as plugin's error message. (See EDIT2 for actual logs)

No System.out.println() because Minecraft(Paper) will complain about using it.
No Logback because I think it is another logging library, thus it cannot work well with Minecraft(Paper)'s logging system (no JDA logs in Minecraft log etc.). I don't want to implement another logging library when there is already logging system provided by Minecraft, which is log4j.

JDA wiki only describes about Logback so I have to find my own way for making JDA with Minecraft's logging system, but it was no success.

For example:

This worked fine for me be building under Java 8. Now under Java 17.01 I get this when I do mvn deploy.

mvn install works fine. I tried 3.6.3 and 3.8.4 and updated (I think) all my plugins to the newest versions.

Any ideas?

I'm parsing a XML string to convert it to a JsonNode in Scala using a XmlMapper from the Jackson library. I code on a Databricks notebook, so compilation is done on a cloud cluster. When compiling my code I got this error java.lang.NoSuchMethodError: com.fasterxml.jackson.dataformat.xml.XmlMapper.coercionConfigDefaults()Lcom/fasterxml/jackson/databind/cfg/MutableCoercionConfig; with a hundred lines of "at com.databricks. ..."

I maybe forget to import something but for me this is ok (tell me if I'm wrong) :

I am trying to compile an existing Spring Boot project using JDK 17 and Maven 3.8.4 and I keep getting this error.

Unable to make field private com.sun.tools.javac.processing.JavacProcessingEnvironment$DiscoveredProcessors com.sun.tools.javac.processing.JavacProcessingEnvironment.discoveredProcs accessible: module jdk.compiler does not "opens com.sun.tools.javac.processing" to unnamed module @521e3470

The problem also occurs with older versions of Maven like 3.6. It also happens with JDK 16. It does not matter what version of Java is configured in the pom.xml via the java.version, maven.compiler.source, and maven.compiler.target. only the JDK version being used to do the compiling... displayed in the mvn -v command.

The project compiles fine using JDK 15. The error happens immediately when compiling starts, right after the INFO message stating how many classes are being compiled. Happens in both my Windows laptop and Ubuntu CI server.

Any ideas what this could be?

EDIT: adding more of the POM file.

Calling mvn clean compile -X

shows the following (few dependencies omitted to stay in question max char size):

My question: when building a minimal JRE, how can one make sure that no required module is missing?

To illustrate the question, here is an example where I want to build a minimal JRE for my project. Let's assume for this example that logback is my only dependency.

I run the following command to see what modules are required:

I am building a Spring Boot application with a MongoDB database and I am running into an issue when the application is deployed to the server and starts logging. I have done some digging on the internet and all the answer I am getting is that I need the following maven dependency and to do an install. I have done that and unfortunately the issue still remains.

I am currently using MongoDB version 4.4.11 and Spring-boot version 2.6.1

pom.xml

We are using spring boot 2.1.5 and starter parent as pom dependency.

Spring boot is using default logback for logging and we haven't explicitly switched to Log4j2 or changes any configurations. Below is our project dependency tree.

We have lot of lombok @log4j2 annotations in our project. But, we find in dependency tree we do not have any log4j2-core jar dependency (that has been found vulnerable to recent issues with log4j).
