Why am I getting Unknown error in line 1 of pom.xml?

Question

Getting unknown error at Line 1 in pom.xml in Eclipse IDE. It was working fine till yesterday, but all of a sudden after updating my project from master and aft

Answer 1

As per the suggestion from @Shravani, in my pom.xml file, I changed my version number in the area from this:

    org.springframework.boot
    spring-boot-starter-parent
    2.1.5.RELEASE
     

to this:

    org.springframework.boot
    spring-boot-starter-parent
    2.1.4.RELEASE
     

I then right clicked on the project and did a 'Maven -> Update project...'. This made the problem go away for me.
