How to checkout other Android versions using repo

[Frank]

Hi all,

I "repo sync" Android source code according to the guide on
http://source.android.com/source/downloading.html.

I executed below repo init command:
repo init -u https://android.googlesource.com/platform/manifest

This will using master branch for manifest, right?

Then, "repo sync" complete, and I can build master successfully
using ". build/envsetup.sh && lunch full-eng && make -j 8".

However, currently I want to build android-2.3.4_r1 .
1). repo forall -c git checkout android-2.3.4_r1
2). . build/envsetup.sh && lunch

Below error occured:

---------------------------------------------------------

You're building on Linux

Lunch menu... pick a combo:
     1. generic-eng
     2. simulator
     3. aosp_deb-userdebug
     4. aosp_flo-userdebug
     5. full_grouper-userdebug
     6. full_tilapia-userdebug
     7. mini_armv7a_neon-userdebug
     8. mini_mips-userdebug
     9. mini_x86-userdebug
     10. full_mako-userdebug
     11. full_maguro-userdebug
     12. full_manta-userdebug
     13. full_arndale-userdebug
     14. full_toroplus-userdebug
     15. full_toro-userdebug
     16. full_panda-userdebug

Which would you like? [generic-eng] 1
build/core/product_config.mk:194: *** _nic.PRODUCTS.[[device/asus/deb/aosp_deb.mk]]: "build/target/product/aosp_base.mk" does not exist.  Stop.

** Don't have a product spec for: 'generic'
** Do you have the right repo manifest?
---------------------------------------------------------

Then, My question is HOW to checkout a pure and buildable android-2.3.4_r1 branch with my repo ?

Any advice is welcome !
Thanks in advance !

To switch to 2.3.4_r1:

repo init -b android-2.3.4_r1 ; repo sync

OK, thanks JBQ.

I have executed below command previously, and all project's git bare repositories
have fetched to my local PC.
repo init -u https://android.googlesource.com/platform/manifest; repo sync

Then, if I execute the command "repo init -b android-2.3.4_r1 ; repo sync",
my previous git bare repos will be removed and re-sync to android-2.3.4_r1 ?

I mean, is all the git repos being re-synced to that version ?

Thanks!

I don't think Repo actually removes any gits from disk, but if it does
it'll only be the gits that exist on the master branch but not in
android-2.3.4_r1. The other way around, i.e. gits in the 2.3.4 manifest
but not on the master branch will be synced from scratch. Remaining gits
will just be updated with the latest state from the server.

Yes. The source workspace will be Android 2.3.4 and equivalent to what
you'd gotten had you passed '-b android-2.3.4_r1' to 'repo init' in the
first place.
