How do I bypass certificate verification errors with Apache HttpComponents HttpClient 5.1?

I've found a working solution to bypass such errors in HttpClient 4.5 that suggests customizing HttpClient instance:

We are using the official Jenkins docker image to run Jenkins serverless. The docker image contains a install-plugins.sh script that can be fed with a list of plugins and their versions, and is run during the image build.

Although Jenkins warns about outdated plugins in the admin backend, is there any way to update that list (format) easily?

The plugin list format looks like

I'm tring to copy from my Ansible server (Ansible 2.11.2 on Oracle Linux 8.4) to remote host (CentOS 7) some files from a list (set in my variable file).
Now I need to check after copy if all are copied correctly, and check the checksum for each files.

My main task used to copy the files from Ansible to remote host is:
tasks/main.yum:

For a Stack Exchange project, I'm downloading various links from all over the internet with a Java program that uses Apache HttpClient. It checks for expired SSL certificates, which can be one of the reasons images aren't visible anymore.

I noticed that sometimes, the Java program thinks an SSL certificate is expired, while my browser thinks it's not. An example is the following URL: https://www.dewharvest.com/uploads/3/4/5/4/34546214/oak-from-seed_orig.jpg

My browser (Firefox on macOS) thinks it's valid:

• Certificate chain
• dewharvest.com (end entity)
• Sectigo RSA Domain Validation Secure Server CA (intermediate)
• USERTrust RSA Certification Authority (root)

but when I run the stripped Java program below, this is what I get:

Ok. So I'm using maven (which honestly just giving me a headache because of reasons like this).

Put this in my pom file:

maven started doing something... you know, Percentage increasing, progress bar etc lower right corner of Eclipse.

Tried to paste in code from this site so I can try out the library: https://github.com/apache/httpcomponents-client/blob/5.0.x/httpclient5/src/test/java/org/apache/hc/client5/http/examples/ClientMultipartFormPost.java

But I get

Cannot be resolved to a type

It ended up here in build path window.

I tried run maven clean. Did not help. I am using Maven project. There is even a small little "M" on my project folder :)

I also found where the jars where and added them manually to webapp/WEB-INF/lib folder. That's why you see them in Classpath in picture above. I'm Using Tomcat. I believe this worked before with gson etc.

It is not often that I need to mess with Maven, so I forget in between, and then each time I spend hours, when in fact I believe it should be a simple thing to add a jar.

Surely I must be missing some common practice of how to simply add a dependency using maven in Eclipse.

I have been struggling for 2,5 hours now.

First of all, There is no comment in source code.

org.apache.hc.core5.ssl.SSLContextBuilder#loadTrustMaterial(org.apache.hc.core5.ssl.TrustStrategy)

my Spring Boot application needs to call RESTful services and I would like to use the apache HttpClient to do so. I added the depency to the pom.xml (tried differenct versions)

I need help with apache http 5 client example described here. My goal is to do exactly the same as CURL:

I've added following task in gradles's rootProject build.gradle file as below. I'm planning to weave AspectJ to compiled classes.
