I'm encountering an issue with spring-boot-starter-test when using it in a modular Java project (Java 9+). Specifically, the transitive dependency on jsonassert includes android-json, which provides an org.json package that conflicts with the org.json package in jsonassert.This issue results in compilation errors when using module-info.java.

Issue Details

  • Spring Boot Version: 3.3.5
  • Dependency Causing Conflict: org.skyscreamer:jsonassert → com.vaadin.external.google:android-json:0.0.20131108.vaadin1
  • Module System: Java 9+ with module-info.java Since spring-boot-starter-test includes jsonassert as a transitive dependency, and jsonassert relies on android-json (which includes org.json), this leads to duplicate org.json packages in modular projects, which Java's module system does not allow.
