Question

I am working on a Hadoop project in Eclipse that depends on another one of my projects; I’ve included the other project in my build path, but when I export the dependent project, it only contains the classes from that same project.

Ordinarily, this would not be a problem, as I could just link the other project with the -cp flag, but Hadoop requires you to pass the jar as an argument, meaning that all of my dependencies must be inside that jar.

Is there a way, in Eclipse, to automatically build and include classes from projects that you depend on?

Thanks.

You can export a project as a Runnable jar, which can be useful if you want a single jar, with dependencies included.

Select the Project. File > Export. Select the Java section. Select Runnable JAR file.
