How to use the org.json Java library with Java 7

问题

I need some simple JSON parsing in my application and the Douglas Crockford library seems exactly what I need.

However, I seem to be running into a problem. I'm getting the following error:

Exception in thread "main" java.lang.UnsupportedClassVersionError: org/json/JSONObject : Unsupported major.minor version 52.0

I Googled around a bit and I get the impression that this is due to some version incompatibility. I've tried changing Java versions but it doesn't seem to help. I'm using Java 7 and Java 7 features in my program and ultimately I want to use Java 7.

How can I resolve this issue?

PS: I looked at Jackson and GSON and definitely don't want to use either so please don't suggest as an alternative.

回答1:

Have you tried using an older version of the package?

Try: http://mvnrepository.com/artifact/org.json/json/20140107

回答2:

Since your are using JDK1.7, change to the older version will work!

<groupId>org.json</groupId>
    <artifactId>json</artifactId>
    <version>20140107</version>
</dependency>
