I have started writing this. I was
stepping through ajc weaving and had the “what’s happening – how did I miss the
weaving step” question. Then I set a break point on the point where weaving
happens and saw there was an aspect advising after compilation, kick off
weaving. Definitely a case where if you don’t know there’s advice (and I didn’t
see it in Eclipse), it can be surprising. But it is good to see the core tools
are using aspects themselves!
I have a simple version working that
creates a weaver & world and basically does these things:
weaver.addLibraryJarFile(new
File(aspectPathLoc));
unwovenClasses = weaver.addJarFile(inJar,
null, false);
binarySourceFiles.put(inJar.getPath(),
unwovenClasses);
copyResourcesFromJarFile(inJar);
weaver.prepareForWeave();
private class WeavingClassFileProvider implements
IClassFileProvider {
…
public
IWeaveRequestor getRequestor() {
return
new IWeaveRequestor() {
public void
acceptResult(UnwovenClassFile result) {
try {
writeZipEntry(result.getClassName(),
result.getBytes());
…
By the way, I saw you had put this idea
forward about a year ago in the bugzilla report about aspectjweaver.jar Wes.

Slimmed down jar for just command line weaving?
You should be able to avoid jar
repackaging. If you use ant to build the module you want, you'll get all that's
required for that module. aspectjweaver.jar is just an alias for the
loadtime5 module, so that should work standalone. To get
ajc, you need only build org.aspectj.ajdt.core
(4.7MB). aspectjtools.jar includes other stuff.
We don't have a weaver-only command-line
or ant interface. You could probably just stick a command-line interface
on WeavingAdaptor, with basic and logging options, in which case you'd only
need to build the weaver module (775K). We've always considered that, but
have had no reason to surface a CLI apart from ajc. Code for parsing
classpaths, etc. should be in util, included by weaver.

Subject: [aspectj-users] Slimmed down jar
for just command line weaving?
I am looking for a way to package a
smaller sized jar to do binary-only weaving of jars. We want to distribute as
small a jar file as possible, and have decided to use a weave on install
approach for this project. Clearly most of what we need is in
aspectjweaver.jar, but not all. It’s pretty important for our needs to have
something more like the 1.5 megabyte aspectjweaver jar rather than the nearly 8
megabyte aspectjtools.jar
Has anyone packaged such a thing? Is
there a small set of jars from the raw aj-build/jars that could be put together
to support this requirement?
