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 after fixing merge conflicts getting "Unknown error" in pom.xml.
Except me, none of my teammates are facing this issue. I also changed the workspace, deleted cache but still no luck.
I am using the h2 database for this project, in spite of inserting values in data.sql, it is not picking up any values and inserting into h2 DB tables. Before this issue, it was working fine. I feel its due to the issue in pom.xml, I am not sure though. Please help
I deleted the existing project and took the latest code from master. After that deleted .m2 folder under users including the repository folder. I did update project and enabled Forced update of snapshots/releases, maven clean and maven build. But nothing helps.

Should remove unknown error in pom.xml and also I must be able to populate values in H2 db.
answer according to current status
This issue got fixed:
Please install the m2e connector for mavenarchiver plugin 0.17.3 from https://download.eclipse.org/m2e-wtp/releases/1.4/
obsolete answer
A less profound change than a downgrade from Spring Boot 2.1.5.RELEASE to 2.1.4.RELEASE would be downgrading only the affected Maven JAR Plugin from 3.1.2 to 3.1.1 as long as this bug exists:
<properties>
<!-- ... -->
<maven-jar-plugin.version>3.1.1</maven-jar-plugin.version>
</properties>
