Cannot deploy artifact to Nexus repository ,status: 401 Unauthorized

I have checked forums and I see that this question was asked before but a very long time ago.
I have a basic application and I am able to create artifacts with mvn package command.

Then I am trying to deploy it to remote Nexus Repo via mvn deploy command ,then I am facing with following error.

I have to mention that I don't have those java.util.List errors on my localhost.
I have no idea where I am doing wrong.

I suggest you to create a file named system.properties in project directory and write java.runtime.version=11. I hope it should work as because this had worked for me.

thx to read.

I finally can...
I had to read those dependencies for project with conflicts, then I download manually, for a weird reason my project cannot access to PrimeFace repository
If org.primefaces.themes fail I just download those files from here:
https://search.maven.org/search?q=g:org.primefaces
then I had to join with my maven2 folder
/Users/$user/.m2/repository/org
Also, I changed the versions of the dependencies.

gwt-maven-plugin can't compile because of "No source code is available for type org.hibernate.validator.constraints.impl.SizeValidatorForString;"

I'm using client-side validation in my GWT web app, and Maven as a build tool. Running in dev mode doesn't cause any problems. Now I want to build the project with Maven, but get multiple errors such as follows:
[ERROR] Line 52: No source code is available for type org.hibernate.validator.constraints.impl.SizeValidatorForString; did you forget to inherit a required module?
[INFO] [ERROR] Line 52: No source code is available for type org.hibernate.validator.constraints.impl.SizeValidatorForCollection; did you forget to inherit a required module?
[INFO] [ERROR] Line 52: No source code is available for type org.hibernate.validator.constraints.impl.SizeValidatorForMap; did you forget to inherit a required module?
[INFO] [ERROR] Line 75: No source code is available for type org.hibernate.validator.constraints.impl.NotNullValidator; did you forget to inherit a required module?
[INFO] [ERROR] Line 83: No source code is available for type org.hibernate.validator.constraints.NotEmpty; did you forget to inherit a required module?
I wish gwt-maven-plugin could see jar source file hibernate-validator-4.2.0.Final-sources.jar while compiling the project. How to manage this resource to make it work? I've tried to put hibernate-validator-4.2.0.Final-sources.jar into src/main/resources directory, but it doesn't seem to work.

Without seeing your pom.xml it's a little difficult to say but my first assumption is that you forgot to add a dependency for hibernate-validator-4.2.0.Final-sources.jar in your pom or there is a versioning problem. Could you post your pom?
Got it:
You have this dependency
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<scope>system</scope>
<systemPath>${basedir}/war/WEB-INF/lib/hibernate-validator-4.2.0.Final.jar</systemPath>
</dependency>
which is the 4.2.0.Final jar BUT you do not have the 4.2.0.Final-sources.jar
Add the dependency for final-sources and you should have your answer.

You need Hibernate Validator 4.1 (not 4.0, not 4.2).
See https://code.google.com/p/google-web-toolkit/issues/detail?id=7661
Note: obviously, for server-side validation, you could use whichever version of Hibernate Validator you want.

you need to have in your classpath both:hibernate-validator-4.2.0.Final-sources.jar and hibernate-validator-4.2.0.Final.jar
just add following to your pom.xml:
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
<classifier>sources</classifier>
<scope>compile</scope>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-validator</artifactId>
<version>4.2.0.Final</version>
</dependency>
