Run Time Error in SchemaJson.toMap()

[santpandey]

I am using 1.6.0 version of the jar. I have created a sample schema and when I run my JSON against this schema, I get the following Run Time Exception:

Exception in thread "main" java.lang.NoSuchMethodError: org.json.JSONObject.toMap()Ljava/util/Map;
at org.everit.json.schema.loader.SchemaLoader$SchemaLoaderBuilder.schemaJson(SchemaLoader.java:160)

Please check if there is an other dependency in your project which uses an older version of org.json. There was a similar issue recently here: #98

It worked. My issue was exactly the same as #98. Thanks

Similar issue.
Found multiple occurrences of org.json.JSONObject on the class path:

    jar:file:/C:/Users/user/.m2/repository/com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class
    jar:file:/C:/Users/user/.m2/repository/org/json/json/20180130/json-20180130.jar!/org/json/JSONObject.class

The jar:file:/C:/Users/user/.m2/repository/com/vaadin/external/google/android-json/0.0.20131108.vaadin1/android-json-0.0.20131108.vaadin1.jar!/org/json/JSONObject.class comes from Spring Boot 1.5.10. There is no toMap() method.

Solution: spring-projects/spring-boot#9248

@santpandey How do you solve this problem?

[santpandey]

@zhjobs When I encountered the problem, I made sure that I was using 20170516 of org.json by manually adding it to pom. After this run mvn dependency:tree -Dverbose command and see whether are you getting old jars of org.json or not. If yes, you must exclude them. Let me know if this helps.

@santpandey Brilliant！It did work! Thanks for your answer!
