Maven NoSuchAlgorithmException when resolving dependencies

my maven installation recently started throwing a NoSuchAlgorithmException when trying to download plugins and/or dependencies. (See stacktrace below). I'm using Intellij Idea community edition, but have tried running mvn clean install from the CLI as well. Same issue.
I've tried a lot of options on SO and other websites but no success. What I've tried thus far are a few variations of the following (I'm on a Windows 10 system):
Upgrade to maven 3.5, was on 3.0
Upgrade and downgrade my java installation to Zulu 19.30.11-jdk19.0.1 and Microsoft jdk17.0.2. This included changing my JAVA_HOME and path variables.
Installed the https://repo.maven.apache.org/maven2/ SSL certificate (repo.maven.apache.org.crt) downloaded via chrome to java folder lib/security/cacerts using the KeyTool.
Add command line args: -Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true
Turn the computer off and on again :D
I have no idea why this is happening, but I hope someone can assist. If you need any further information, please let me know.
Stacktrace from CLI after running mvn clean install -X when trying to build this JavaFX project from Github source:

After searching a bit further when updating to maven 3.8.7, I inspected my Path variables and noted the following System Variable:
MAVEN_OPTS
-Xmx512m -Djavax.net.ssl.trustStore=/Library/Java/JavaVirtualMachines/jdk-11.0.8.jdk/Contents/Home/lib/security/cacerts -Djavax.net.ssl.trustStorePassword=xxxxxxxx
This pointed to a specific certificate - leading all my maven versions to use an outdated or possibly deleted certificate. I deleted this variable and the maven build worked.
I checked all the other java and maven variables and made sure they make sense.

ArtifactDescriptorException when running a clojure hello world in a docker container

I'm getting ArtifactDescriptorException: Failed to read artifact descriptor for org.clojure:clojure:jar when running a literal hello world program using the command clojure -M file.clj in a docker container. No issue doing it locally. Some googling suggests it might be a maven issue but there're no dependencies so I don't see why it's trying to get anything from a maven repo.
Full error output:

1 error
I tried to change the local-developer-group url in settings.xml of my maven installation to http://repo.spring.io/snapshot/ since the error report clearly says the required artifact cannot be found, but still I got the the same error. It seems the spring-boot-cli doesn't use the settings of my maven installation. But I couldn't think of another place where this url can be specified.

You should use the release version of spring-boot-cli instead of the cutting edge snapshot version: Manual installation.
The maven settings.xml spring-boot-cli uses is located in the .m2 directory.

Cannot start groovy application with spring cli command

I downloaded and installed the latest version of spring cli (1.5.1), i created a groovy file with #RestController and #RequestMapping but when i try to run it i have these errors.

I read to run it a couple of times and it should work but it doesn't.

Its most likely due to network or proxy related issue. Please follow the link
https://docs.spring.io/spring-boot/docs/current/reference/html/cli-maven-settings.html
Also you should set JAVA_TOOL_OPTIONS env variable:
-Dhttp.proxyHost=YOUR_PROXY_HOST -Dhttp.proxyPort=YOUR_PROXY_PORT -Dhttps.proxySet=true

Maven not working when 'mvn package' command is run

I am working on a Spring mvc using Eclipse. Until now I was using ant to create war file. But now I switched to Maven. I have copied Maven 3.3 on my system and set system variables for Maven. It works fine, when I run Maven following command from command prompt:
mvn -version
I have created a pom.xml file in my Spring mvc app's root directory. I run Maven through command prompt, not through Eclipse. When I run following command:
mvn -X package
it shows following errors:

It says connection timed out, but my internet is running fine.

199.27.79.215 is not the right IP address for repo.maven.apache.org. The right IP address is 23.235.40.215 (as of 9/10/2015 from my desktop). If I open a browser to https://199.27.79.215/, I get a web page which says unknown domain: 199.27.79.215.
The problem is that Maven is being run in an environment without a direct connection to the Internet. Maven needs to be configured to go through the HTTP Proxy. The Maven documentation for this is found here. Here's the information...
Configuring a proxy
You can configure a proxy to use for some or all of your HTTP requests
with Maven. The username and password are only required if your proxy
requires basic authentication (note that later releases may support
storing your passwords in a secured keystore - in the mean time,
please ensure your settings.xml file (usually
${user.home}/.m2/settings.xml) is secured with permissions appropriate
for your operating system).
The nonProxyHosts setting accepts wild cards, and each host not to
proxy is separated by the | character. This matches the JDK
configuration equivalent.
<settings>
.
.
<proxies>
<proxy>
<id>example-proxy</id>
<active>true</active>
<protocol>http</protocol>
<host>proxy.example.com</host>
<port>8080</port>
<username>proxyuser</username>
<password>somepassword</password>
<nonProxyHosts>www.google.com|*.example.com</nonProxyHosts>
</proxy>
</proxies>
.
.
</settings>

I found that setting my MAVEN_OPTS environment variable worked. Apparently JDK7 has some issues with it: https://issues.apache.org/jira/browse/MNG-5162
export MAVEN_OPTS="-Djava.net.preferIPv4Stack=true"

You are using the repository which is available at
repo.maven.apache.org:443 [repo.maven.apache.org/199.27.79.215]
and as the error says, maven is not able to reach that URL:

Check your internet connection and make sure you are able to reach the repo. You can test it by trying to hit the URL in browser or by using curl
