如何从包括库的Eclipse项目制作jar文件？

Question

I want to make my project into a jar executable.

That much I can do but I need my external library as well.

How do you specify the location of an external library? Right now I have added it to my eclipse project,but later on I need it to execute my program outside of eclipse on a server.

The Library is the postgres-jdbc driver to connect to database.

Answer 1

Do you mean Fat Jar or Runnable Jar ie a single jar which will contain all it's dependent jars in it.

If yes, it can be generated in eclipse using File -> Export -> Java -> Runnable Jar

Optionally you can specify the start-class having the main method.

If you don't want as a Runnable jar , you've to add all your dependent jars in classpath before starting your application.

java -cp <add all lib> -jar <jar-file-name>.jar
