incremental support on the command-line
I'm not sure of the historical reasons for that
limitation (expediency of implementation?), but I can't immediately see any
reason why we couldn't support incremental compilation using a list of source
files as opposed to sourceroots (by the time we get to actually compile, the
origin of the source files is lost anyway). A full ".lst" file
has more implications - it can contain a whole host of compiler directives. We
also don't say in the docs (that I could find) whether we support injars,
inpath and aspectpath with incremental compilation. They currently don't work
(any changes in resources on these paths will be ignored I believe), but the
compiler accepts them. Copying of resources (only an issue if inxxx is
allowed) is also broken under incremental (no changes detected again). We also
allow the user to specify -outjar, but that's broken too.
[Just
to qualify - when I say 'broken', I don't mean it all falls down in a heap,
just that not all cases are handled correctly.]
All
of these things will be needed by AJDT, and I propose to extend our incremental
capability to cover them (even if in the very simplest case we simply revert
back to a batch build on change detection). Once that is done and the tests are
in place, I see no reason to continue to limit the command line (or ant)
incremental compiles. AJDT has to cope with classpath etc. changes between
compiles, and will follow the JDT rule - if any path element changes, then do a
full build.
I
raised bugs 54618, 54621, 54622, and 54625 last week to cover these issues. The
next challenge is supporting tests of this nature in the test harness...

incremental support on the command-line
|
We
used to say -sourceroots is required to support incremental on
the command-line, but we seem to be able to
implement incremental
using .lst files in AJDT. True? Will
there be a continued
need for this limitation on the command-line
compiler in 1.2?
Thanks -
Wes
