Classes.jar and classes-header.jar with same module name

[Pranitha Reddy]

Hello

Say there is module 'X' writtern twice in Android.mk

include $(CLEAR_VARS)

LOCAL_MODULE               := X

LOCAL_MODULE_CLASS         := JAVA_LIBRARIES

LOCAL_SRC_FILES            := same_path/classes-header.jar

include $(CLEAR_VARS)

LOCAL_MODULE               := X

LOCAL_MODULE_CLASS         := JAVA_LIBRARIES

LOCAL_SRC_FILES            := same_path/classes.jar

Is there any way to install X such that both classes.jar and classes-header.jar will be in out folder?

At present with above Android.mk, the rule that is writtern first is being compiled and the rest is being ingnored and so Im seeing only classes-header.jar in out folder

Thanks in advance

That generally should be an error, as we normally require modules to be unique based on the combination of LOCAL_MODULE / LOCAL_IS_HOST_MODULE / LOCAL_MODULE_CLASS (this is in build/make/core/base_rules.mk)

If that isn't triggering, you may be making two rules to create the same /system/frameworks/X.jar, and you should be getting a warning like this:

build/make/core/....mk:LLL: warning: overriding commands for target `out/target/product/mydevice/system/frameworks/X.jar'
build/make/core/...mk:LLL: warning: ignoring old commands for target `out/target/product/mydevice/system/frameworks/X.jar'

That should be an error by default unless you've got BUILD_BROKEN_DUP_RULES set (at least as of Android-Q iirc). That means you're getting one of the two, or sometimes a mix, but we don't really even guarantee which one you'll get (it's fairly stable, but can change based on ordering/etc).

What did you intend for the snippet to do? How would we install both classes.jar and classes-header.jar onto the device? Same filenames? Different filenames? Why do they share the same module name?

Yes they share the same module name,  but different srcs, one source is classes.jar and other is classes-header.jar, however we r not facing module duplication here, Is there any possible way to install the module such both classes.jar and classes-header.jar are compiled. The present scenario one override other.

 

Note that one rule is to make classes.jar and other rule is to make classes-header.jar

Thank you:)
