PKIX path building failed when doing mvn install

Question

I tried to do mvn install on my Maven project. But I get the error:

[ERROR] Plugin org.apache.maven.plugins:maven-clean-plugin:3.1.0 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-clean-plugin:jar:3.1.0: Could not transfer artifact org.apache.maven.plugins:maven-clean-plugin:pom:3.1.0 from/to central (https://repo.maven.apache.org/maven2): Transfer failed for https://repo.maven.apache.org/maven2/org/apache/maven/plugins/maven-clean-plugin/3.1.0/maven-clean-plugin-3.1.0.pom ProxyInfo{host='MYCOMPANYPROXYHOST', userName='null', port=8080, type='https', nonProxyHosts='null'}: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target -> [Help 1]

I get an error telling me that Maven couldn't find the certificate, I searched almost every website to find a solution.

What I have tried :

I changed the Maven settings file, my settings.xml file is like below:

 <proxies>
     <proxy>
         <active>true</active>
         <protocol>https</protocol>
         <host>MY_COMPANY_HOST</host>
         <port>8080</port>
         <username>MY_USERNAME</username>
         <password>MY_PASSWORD</password>
         <nonProxyHosts>localhost</nonProxyHosts>
     </proxy>
     <proxy>
         <active>true</active>
         <protocol>http</protocol>
         <host>MY_COMPANY_HOST</host>
         <port>8080</port>
         <username>MY_USERNAME</username>
         <password>MY_PASSWORD</password>
         <nonProxyHosts>localhost</nonProxyHosts>
     </proxy>
 </proxies>

I went to https://repo.maven.apache.org/maven2 and downloaded the certificate, then I added it to the cacerts, with the command:
```
keytool -import -alias example -keystore  .\cacerts -file example.cer
```

Details :

The cacerts file is in %JAVA_HOME%\lib\security.
I could obviously go to https://repo.maven.apache.org/maven2 on my Web Browser, since I've downloaded the certificate.
I am on Windows 10, 64 bits

EDIT:

The command mvn -version show gives:

Picked up JAVA_TOOL_OPTIONS: -Djava.vendor="Sun Microsystems inc."
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: C:\Users\MYUSER\Desktop\Code\apache-maven-3.6.3\bin\..
Java version: 1.8.0_73, vendor: Sun Microsystems inc., runtime: C:\Users\MYUSER\Desktop\TEST\05-Environnement_dev\Tools\Java\jdk-8u73-windows-x64\jre

OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"

EDIT 2:

I tried to use Eclipse, instead of the Maven command. And I could verify this:
When I change the username or the password I get the error Failed to authenticate with proxy, and modifying the proxy host changes the error message. I can now guarantee that the proxy settings are correct.
(This step actually has cost me half an hour with the IT service, because I failed to authenticate with the proxy multiple times).

what does mvn -version show. Is it the same java where you have installed the certificate ? — SKumar, Oct 01 '20 at 13:21
I assume the java path is different from %JAVA_HOME%. Have you tried this ? https://stackoverflow.com/a/17620644/11244881 — SKumar, Oct 01 '20 at 13:29
Really intersting, I htink ir's actually my problem, I'll write the solution when I find it. Thank you — Junior, Oct 01 '20 at 13:36
Sadly the problem wasn't from that, Maven is using the jre that I want. — Junior, Oct 01 '20 at 14:31

Try adding -Djavax.net.ssl.trustStoreType=WINDOWS-ROOT to the maven JVM options so it uses the root certificates from Windows
