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
<https://cs.android.com/android/platform/superproject/+/master:build/make/core/base_rules.mk;drc=fca369e4e3694b0f549613362f056ffff8c88f67;l=322>
)


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?
