How to force re-build of external jar on run of android app? [message #760940]

This might be a fairly general Eclipse question but since I've run into some Android-related specifics in my development before, I am asking my question here. I am fairly new to both Android dev and Eclipse so I suspect this q might be fairly basic.

I have an Android project (let's call it pA) that depends on an external JAR exported in a regular Java project (let's call it pE). Right now, when I change something in pE's source and then want to run the pA app, I follow these steps:

1. Modify source in pE
2. Delete its existing JAR
3. Export pE
4. Do a refresh of pA
5. Run/debug pA

I am probably doing extra work here. What's the easiest way to force a re-build/re-export of pE when I run/debug pA? Can I do steps #2-4 automatically by performing a single operation within pA?

Thanks!

I don't know if it will be different with Android development, but with normal java projects, one generally adds the pE project as a dependency of pA and that should work.

I tried that by going to Properties of pA -> Project references and checking pE. However, when I tried to run pA, I got this:

java.lang.IllegalArgumentException: already added...
...
Conversion to Dalvik format failed with error 1

Any idea why?

Thx
