When you touch code in a module then you can use "make <module>" to
just
rebuild that module. If you use "make" then it will rebuild that module
and all other modules that directly or transitively depend on it. There
are some tricks with sjavac but that is essentially it.
So which module are you changing? Is this Windows? Are you re-building
images each time?
My changes are in java.desktop and jdk.accessibility, split between
Java, Win, and Mac code. I typically run "make images". If I do "make
java.desktop" will that recreate files in images/jdk(jre)/bin? At some
point soon I'll also be working in the JavaFX space but I think that's a
whole different story.
"make java.desktop" will only update the files in <outputdir>/jdk/bin,
the "exploded image". For some usecases that image works well enough and
saves you some time.
The complete images step is, as has been pointed out by others in this
thread, quite slow these days. There are some improvements incoming but
it will likely never be considered fast in comparison.
So what build target will ensure the exploded image is created and up to
date?
Thanks,

If you are re-building images every time then you'll see it creates the
jmods (packaged modules too). It is a bit expensive at moment, partly
because each package module generates hashes of the module artifact of
each dependency. This has been changed in an upcoming refresh so that
the hashes are generated and recorded once, this in turn allows for
more
concurrency when generating the packaged modules. This may help you,
but
hard to say.
Just to add my concerns here, I was changing the launcher and building
images and that caused the jmods to be rebuilt as well. I would not
expect that so do we have missing dependency information in the build?
