Android Eclipse - Cannot see annotation processing option

Question

I am unable to fine the option to set annotation processing in my Eclipse preferences.

Answer 1

It seems Google removed the Annotation Processor option from project properties in the ADT bundle. We are tracking the problem in this AndroidAnnotations issue. The current workaround for this is not installing the bundle, but downloading a standalone Eclipse distribution and adding the ADT plugin to that.

Answer 2

If annotations.jar is missing, it maybe ADT 23 related problems.
Check this.

Update eclipse with Android Development tools 23

Google response:
...
and copy over the following files:

tools/hprof-conv
tools/support/annotations.jar
tools/proguard

(Added) If its ADT bundle problem (part of ADT 23 related problem),
this part is for you. (Linked above)

Google response:

This is a packaging bug. The entire proguard file is missing. We'll have an update asap, but until then just copy it over from a previous version of the tools:
...
Edit: with the latest ADT release, the bundle should now work with auto-update, so install these new versions:

linux 64 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
linux 32 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip
mac: http://dl.google.com/android/adt/adt-bundle-mac-x86_64-20140702.zip
win32: http://dl.google.com/android/adt/adt-bundle-windows-x86-20140702.zip
win64: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip

Don't try to upgrade from previous version because it doensn't work at all. If you have got problems with zipalign, it's now under platform-tools and no more under tools/ so you can do a symbolic link or just copy it into the expected folder.

or use "not-bundled" Eclipse.

Answer 3

Copied APTDemo.jar from http://www.eclipse.org/jdt/apt/APTDemo.jar in the lib folder and I can see the option in my compiler preferences. I will investigate later, fixed my problem for now.
