Pubsubhubbub – an extension to Atom (and RSS)

Create Runnable Jar - Eclipse Options

So, the runnable JAR will not only contain the .class files of your application, but also the .class files of all the libraries your application uses. Package required libraries into JAR - Puts the actual JAR files of the libraries into your runnable JAR. Normally, a JAR file within a JAR file cannot be loaded by the JVM. But Eclipse adds special classes to the runnable JAR to make this possible. Copy required libraries into sub folder next to JAR - Keeps the library JARs completely separate from the runnable JAR, so the runnable JAR will only contain the .class files of your application. Option #2 is convenient be…
