Note that the unit tests were successfully run in the pipeline. Just suddenly stop working on my local machine. Any clue?

The answer is in your stack trace: Could not find a valid Docker environment. Please see logs and check configuration.
The class not found is misleading, it is attempting to create the instance but the native code in the constructor is failing, so it considers it a NoClassDefFoundError error. Errors indicate that there are JVM problems, in this case the foreign JNI code is failing.
Make sure that you have docker installed and that your user has all the required rights to start a test container.

I bet Bill's answer must be correct in most cases. However, for my case, I did have Docker started. The issue is somehow my jdk was suddenly updated from 1.8 to 11. Not sure how did that happen. But once I reinstall 1.8 and set it as my java_home, everything works fine.

Reactor - RxJava - "Duplicate found in causal chain so cropping to prevent loop" When Using Flux

When running the code snippet at the bottom, a failure occurs inside the CompositeException. The underlying cause of the failure is
Caused by: java.lang.RuntimeException: Duplicate found in causal chain so cropping to prevent loop ...
It would seem that the instance of CompositeException is being reused by each invocation of flatMap which is why it is seeing the same exception twice.
The expected behaviour is that first element emitted from the flux will be transformed into an error signal, causing the remaining elements to be cancelled and a Flux with an error signal being propagated down the signal chain.
Flux.just(1, 2, 3)
.flatMap(i -> RxReactiveStreams.toPublisher(Observable.error(new NullPointerException())))
.subscribe();
Can anyone explain why this behaviour is occurring and what can be done to mitigate it?

I think using RxReactiveStreams.toPublisher() is wrong here. If you want to experiment with error happening in the stream, you should map it to Observable.error() and see how it goes.
From this similar thread with the same exception:
What's happening is that your onError implementation in a Subscriber is throwing an unchecked exception which is against the Observable contract and this aborts the observable processing throwing an OnErrorFailedException in the observeOn scheduler.
This can be seen in your stack trace:
rx.exceptions.OnErrorFailedException: Error occurred when trying to propagate error to Observer.onError
at rx.observers.SafeSubscriber._onError(SafeSubscriber.java:187)
As a sidenote, RxJava 1 was end-of-lifed in 2018 and it shouldn't be used anymore anyway.

java.lang.UnsupportedOperationException: This feature requires ASM8_EXPERIMENTAL

I try to run the application using spring boot + jdk14(records) + junit5 + maven, but unfortunately, I cannot address an issue with asm. In the internet I only could find this asm GitLab commit. Afaik this is an experimental feature and there is no official build. So, then what is the way to run project on jdk14?
Find below a stacktrace:

Looks like ASM changes were merged to Spring Core 5.2.4. You can rollback to Spring Boot 2.3.0.M2 which uses Spring Core 5.2.3

This is now fixed in Spring Framework 5.2.5, and Spring Boot 2.3 M4 (the next release due in about a week) is already using this version so it should be solved.

How to fix the error Caused by: java.net.BindException: Address already in use: bind in Quarkus?

I've created a quarkus quick start project with
mvn io.quarkus:quarkus-maven-plugin:0.13.1:create \
-DprojectGroupId=com.demo.quarkus \
-DprojectArtifactId=quarkus-project \
-DclassName="com.demo.quarkus.HelloResource" \
-Dpath="/hello"
And afterwards when I run:
mvn clean package
I get the following error:

The origin of the error seems to be coming from
#QuarkusTest
public class HelloResourceTest {
#Test
public void testHelloEndpoint() {
given()
.when().get("/hello/filipe")
.then()
.statusCode(200)
.body(is("hello"));
}
}
I'm not sure which port it is trying to bind to. I suppose 8080.
Any ideas how to override the default port using the application.properties?
I'm on windows.
Thanks!

It seems that besides the normal HTTP port, there is also a default port used during tests. So in order to override the default port used in tests, the following property needs to be overridden:
quarkus.http.test-port=8888
This will run the rests using port 8888.
The answer for this question pointed me in the right direction:
How can I configure the port a Quarkus application runs on?
As well as the comment pointing to
https://github.com/quarkusio/quarkus/blob/0.14.0/extensions/undertow/runtime/src/main/java/io/quarkus/undertow/runtime/HttpConfig.java
More info here:
https://quarkus.io/guides/getting-started-testing#controlling-the-test-port

It seems to use 8080 by default.
Quarkus itself is configured via the same mechanism as your application. Quarkus reserves the quarkus. namespace for its own configuration. For example to configure the HTTP server port you can set quarkus.http.port in application.properties.
