This is The Exception

You need to have the right runtime for your class files installed. In your case are you using java 17 to compile it but are trying to run it on java 15. So you can change your pom.xmlfile or install the right JRE

All I have done is changing the java.version to 15
What you are trying is like write an app and build it for Windows 11 but then run it on Windows XP
Change The version of Spring 2.7.7 like below, it will work
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.7.7</version>

I expect my app to serve login module by default but base href
<base href='/'></base>
property is "/" for all so I am getting 404 error for my styles and Js files.
Also it would be of great help if some one helps me to figure out how to achieve this in a micro-services architecture.
I know there seems to be a lot of discussion on StackOverflow about the error I am getting, but I don't see exactly the same situation and I'd like to better understand the issue I am having.
I am getting the following failed to start error "Caused by: org.apache.catalina.LifecycleException: A child container failed during start"
After doing some research it seems like this is a WEB-INF/lib and/or a pom.xml dependency issue. It looks like people have been able to solve their issues by removing a variety of jar files or updating their pom file/removing a variety of certain dependencies.
When I look at my WEB-INF/lib jar files, it seems that mine are duplicating... Does any one know why I am getting double/2 versions of the same jar files, and could they tell me which dependency they are coming from in my pom.xml file? I think my project wont start on Tomcat & is getting this issue due to the duplicates, as things are already running once when it tries to start the other duplicate jar files.

Here's a snip of my WEB-INF/lib jars, showing some duplicates.
I have deployed a spring boot project on open shift stater gen 3. It was perfectly a few days ago. But yesterday I rebuilt it and it gave me this "Application is not available".I deployed it through this.

The build and deployment is working just fine no error at all
When I'm trying to install Maven dependencies using mvn install or build project with mvn clean package, Maven starts to download files from the central repository, but at some point, downloanding hangs. Here is the output:
[INFO] Scanning for projects...
Downloading from central:
https://repo.maven.apache.org/maven2/org/springframework/boot/spring-
boot-starter-parent/1.5.9.RELEASE/spring-boot-starter-parent-
1.5.9.RELEASE.pom
Progress (1): 7.5 kB
and nothing happens next.
In this case, downloading hangs at first dependency, but when I'm creating new Maven project and write nvm install some things downloads correctly and suspension takes place later.
I tried to remove all things from ~/.m2 directory, but still the same. No firewall is used.
The environment I working with is Java 9.0.1, Maven 3.5.2 on Ubuntu 16.04. I'm a total beginner in Java, not using any IDE, just on terminal to starts a local server with REST API.
