Java object to JSON jar package configuration __java

In fact, there has been done to the Java object to the JSON array, JSON object, but at that time already provided the jar package, and today need to turn Java to JSON, but no jar bag, had to find their own online, looking for the time encountered a lot of pits AH. Remember, it also prevents me from coming across this kind of thing again.

We'll need these bags altogether.

The version of these packages is very fastidious, some version of the package, directly to the package name changed, such as the collections package, 4.x version, the package name directly into the Collection4 what, the other jar bag or old bag name, There will still be classnotfoundexception. So the version is important.

Anyway, according to my version is available.
