使用Eclipse将具有外部依赖项的Java项目导出到jar

Question

Is there an easy way to export a Java project including all of its external dependencies to a standard .jar file?

I have developed an SDK that uses several Apache libraries and I would like to be able to ship this project as a single jar. The answers I have found thus far to this question require the project to be packaged as a Runnable jar, and does not apply to this project which has no main class.

The rest of the answers I have found assume familiarity with Ant or Maven to accomplish this task, and I have no background with either. There are several scripts out there but I don't understand how I would use/modify them, or what I would to run the script and get a result.

Any answer that can provide more background into how exactly a user with no background with Ant or Maven would do these tasks is greatly appreciated.

For more background information I have trying to combine the following libraries into one called JetstreamSDK.jar

commons-codec-1.6.jar
commons-configuration-1.9.jar
commons-io-2.4.jar
commons-lang-2.6.jar
commons-lang3-3.1.jar
commons-logging-1.1.1.jar
httpclient-4.2.5.jar
httpcore-4.2.4.jar
JetstreamSDK-Java.jar
jibx-bind.jar
jibx-extras.jar
jibx-run.jar
xpp3.jar

Answer 1

jar file is like zip compressed file. Usually Eclipse (default) java project will be organized like following directory structure:

some_project
       |____ src/ <--- your java source files
       |____ bin/ <--- compiled class files
       |____ lib/ <--- 3rd party libs e.g. commons*.jar

To package above structure and distribute as a single jar (zip) file- go inside bin/ directory and select everything inside and just right click (assuming you are working on windows) and send to compressed (zipped) folder. Give a suitable name to the generated zip file eg your-sdk.jar then right click on lib/ and compress into a another zip together with your-sdk.jar and you are done. This can be accomplished using jar command line tool also- but, you have to read the jar options/help on how to do this.

Answer 2

1.) First compile your project

2.) Right click on your PROJECT -> Export -> Java -> Runnable jar

3.) You will get a Dialog box, there select the class name (in which your main method resides)

4.) Give the export destination

5.) In library handling(radio button): select your desired option(all are self descriptive)
