Non-parseable POM SpringBoot - maven

Question

My Project was working fine then I needed to add a dependency, After
adding the dependency I was not able to Import class file from newly
added dependency so I Updated the project Maven, Update Project after
that I started facing this issue.
I have tried these options.
1: Deleted .m2 directory
2: Deleted workspace
3: Re-Installed Maven
pom.xml:

Answer 1

I am able to solved the issue by these steps.
Updated SpringBoot version 1.4.3.RELEASE to 1.5.14.RELEASE.
Closed the eclipse.
Deleted .m2 directory.
Open project in eclipse.
Maven Update Project.

Answer 2

Not sure why you added javaxt as repository, but it is giving you the wrong content for the spring-boot-starter-parent.
just click on http://www.javaxt.com/maven/org/springframework/boot/spring-boot-starter-parent/1.4.3.RELEASE/spring-boot-starter-parent-1.4.3.RELEASE.pom and you'll see the content. It should be a pom, but it is not.
I'd suggest removing or replacing the repository.

Answer 3

If the XML is well formed and there are no issues with the repositories, try using the previous version of Spring boot starter. Example -
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.2.2.RELEASE</version>
<relativePath/> <!-- lookup parent from repository -->
</parent>
And do a maven update, it should work.
