or you can just call javac *.java and jar cfv json-java.jar *.class

Hey, thanks for the answer!

That will work for sure, if you don't need the package (org.json) on internal directories of the .jar file. Doing exactly what you pointed will give me the following structure:

 $ jar tf json-java.jar 
META-INF/
META-INF/MANIFEST.MF
CDL.class
Cookie.class
CookieList.class
HTTP.class
HTTPTokener.class
JSONArray.class
JSONException.class
JSONML.class
JSONObject$1.class
JSONObject.class
JSONObject$Null.class
JSONPointer$Builder.class
JSONPointer.class
JSONPointerException.class
JSONString.class
JSONStringer.class
JSONTokener.class
JSONWriter.class
Property.class
XML.class
XMLTokener.class

Using the Apache Ant task provided, I get:

$ jar tf JSON-java.jar 
META-INF/
META-INF/MANIFEST.MF
org/
org/json/
org/json/CDL.class
org/json/Cookie.class
org/json/CookieList.class
org/json/HTTP.class
org/json/HTTPTokener.class
org/json/JSONArray.class
org/json/JSONException.class
org/json/JSONML.class
org/json/JSONObject$1.class
org/json/JSONObject$Null.class
org/json/JSONObject.class
org/json/JSONPointer$Builder.class
org/json/JSONPointer.class
org/json/JSONPointerException.class
org/json/JSONString.class
org/json/JSONStringer.class
org/json/JSONTokener.class
org/json/JSONWriter.class
org/json/Property.class
org/json/XML.class
org/json/XMLTokener.class

The latest seems to be the "official" way to create .jar files with package names defined on the source code [1][2][3] and make it easier to create it, of course, if you use Apache Ant. ;-)

The release project already handles the packaging paths. If you read the FAQ you will see that we don't want build tool integration in this project.

Uh, ok so. But I have a point on the internal directory structure! ;-)
You can close the pull request, I'll keep the Apache Ant build file on my fork. :-)
Thanks!

@taq, thanks for the pull request. As discussed, this project has a longstanding policy of not supporting any particular build tool, so the PR cannot be accepted. However, I think you made a valid point. Furthermore, new users may be puzzled about how to build their own jar file. Please feel free to add wiki text explaining how to correctly build the code, using whatever build tools you think appropriate. At the present time, the wiki pages should be open for editing by any interested party.

@taq, The maven version is maintained by @BGehrels and can be found in the https://github.com/BGehrels/JSON-java repository if you are interested. This is what is used to release to maven-central
