Using the JAR Packager

The IDE's JAR Packager enables you to create a single JAR (Java Archive) file from a hierarchy of files.

In the IDE, you make a JAR file by first creating a JAR Recipe file. The JAR Recipe file stores information about the JAR to be created, such as files to be included, location, manifest text, and compression level. You create the JAR file itself by calling the Compile command on the JAR Contents file.

If any of the files that the JAR file is built from change, you can recompile the JAR Contents file to update the JAR file. You can also make changes in the JAR Contents file then compile it to create the modified JAR file.
