The JSON license is not approved for use by Eclipse projects
The pom.xml file lists org.json:json
as a dependency. This content is distributed under the terms of the JSON license which includes a field of use restriction and so is not approved for use by Eclipse projects.
I recommend org.glassfish:jakarta.json
as an alternative.
Note that you can use the Eclipse Dash License Tool to vet the dependencies described by your Maven build, and request reviews for content that requires review.
While I have your attention, the repository also needs the standard legal documentation files (LICENSE, CONTRIBUTING).
