[cbi-dev] CBI "clean" build and SWT
|
Hi,
while trying to understand why my SWT source changes are not reflected in
the CBI build, I think I found a problem with the "clean" build.
In my expectation (I'm not maven user at all) if I say "mvn clean install"
it should do the "clean" build in the sense that all previously generated
build artifacts are first deleted, and then the full source build starts
from scratch.
At least for SWT build it seems to be not true.
SWT builds different Linux platform flavors from the generated java code,
which uses same source files as common origin. SWT build do some
pre-processing and generates plattform specific sources before starting
compiler. This way SWT can build x86 and x86_64 java code from "same"
original java file.
So if I understood how CBI build works, it takes SWT "origin" from
/eclipse.platform.swt/bundles/org.eclipse.swt/Eclipse SWT/gtk
and generates two "children":
/eclipse.platform.swt.binaries/bundles/org.eclipse.swt.gtk.linux.x86/src
/eclipse.platform.swt.binaries/bundles/org.eclipse.swt.gtk.linux.x86_64/src
from which is then generates .class and .jar artifacts.
So my naive approach to patch some SWT code was to change files located
under the "origin" path and expectation was that the modified code will be
properly re-generated to the "children" directories.
This works only the first time I'm starting the CBI build.
Each consequent CBI build (which calls "mvn clean install") seem to ignore
any changes on "origin" files and generates binaries from the out-of-date
"children" directories.
I'm using the original CBI wiki build commands to run the build with
binary pieces, no extras at all except modified SWT code.
Can you confirm my observations?
Do I miss some extra steps for "maven clean build" executed second time?
Can it be that maven is not aware of that extra SWT generated source
folders, so it doesn't properly perform cleanup? Should I report a bug for
that then?
Thank you!
