Hello, everyone

I have two version .bb recipe, sya test_1.0.bb and test_2.0.bb.
When build the `test` package  using the flowwing cmd:
    bitbake test
Always 2.0 was built.
My question is: how to let bitbake to build version 1.0 of the test package

You can add PREFERRED_VERSION_pn-test = "1.0" in local.conf
or you can add DEFAULT_PREFERENCE = "-1" to test_2.0.bb

Thanks very much.
Now I use the second option.

Hi,
I do see two options for you.
1.) As explained by the folks already you create two build directories which share download and sstate folders. Then you create one local.conf with the "Production Version" and one with the "Development Version". Depending on which build folder you utilize you get the product or development version. 
2.) If you incline to use the command line to switch, there is the option to specify a config file explicitely read by bitbake. If called with "-R product.conf" you get your product version and otherwise you stick with Yocto choice of taking newest one.

Example:
bash-4.3$ cat -> product.conf
PREFERRED_VERSION_test="1.0"
bash-4.3$ bitbake -R product.conf test
...

Option One is the most conflict free variant as your configurations are cleanly separated and your calls to bitbake are identical. At the cost of having the build directory two times and two different environments (Shell instances).
Option Two is risky if you do not tell bitbake to clean (bitbake -c cleanall test) from the former build as you may end up with a mixed sysroot.

Hope this helps.

You can't select everything from the commandline. Its for the reasons
of reproducibility that we suggest people set things in configuration
files like local.conf. You can then provide the exact configuration to
reproduce any given build by saving that configuration file.

Thanks for your repley.

Your suggested method can select any version sure.

But whenever I finish  my project. some time later I wan't rebuilt this 
project.
Then I must edit the source to select specific version. It is not 
convenient and buggy.
Is there a way to select version that no need to edit the source, e.g. 
select it on command line

You can:
1) PREFERRED_VERSION_test = "1.0" in conf file such as local.conf
Or:
2) Set DEFAULT_PREFERENCE = "-1" in test_2.0.bb.

Hello, everyone

I have two version .bb recipe, sya test_1.0.bb and test_2.0.bb.
When build the `test` package  using the flowwing cmd:
    bitbake test
Always 2.0 was built.
My question is: how to let bitbake to build version 1.0 of the test package
