• com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class
• org/json/json/20140107/json-20140107.jar!/org/json/JSONObject.class

exclude掉android-json，就可以了

        
            org.springframework.boot
            spring-boot-starter-test
            test
            
                
                    com.vaadin.external.google
                    android-json
