Is there a way to force Eclipse to automatically clean every run?

Question

I am developing for Android and use Eclipse to create an apk that also has a .so file with C++ code in it. My problem is that when I only change the C++ code and recompile that outside of Eclipse, Eclipse doesn't really always see that it's changed and I have to clean the project and rebuild it before I can reliably start it. This behaviour has cost me lots of time because Eclipse is not using the new .so file.

Is there a way to force Eclipse to always rebuild the project before its being run ?

Answer 1

In Project Options, go to "C/C++ Build.

Select "Builder Settings" tab.

Uncheck "Use default build command" and in the field Build command, just add the target "clean" as the first target.

E.g. assuming you have

> make -j2 settings

change it to

> make clean -j2 settings

I'm not sure how familiar you are with ant, but if you are compiling your c++ files through command line, one thought is to create an ant build script that will:

• recompile your c++ files
• clean and build your apk
• install your apk onto your device

Then you can be sure the generated apk is always built using the latest compiled code.
