RE: [ajdt-dev] Unable to effectively develop w/ AJDT active duetoconstan

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

I tried it out and have found three significant causes of unnecessary
incremental compilation:

1. Incremental rebuilds are happening whenever ANY file changes in an
AspectJ project, not just in a source, classpath, aspectpath or inpath
entry. For example, if I create a new text file at the top-level not in my
source path, that triggers an incremental rebuild. If my running program
appends to a log file (again not in my source path), that does it too. So
when I run a unit test that writes to a log, that results in a rebuild. 

2. Incremental rebuilds trigger when a dependent project rebuilds, even if
there were no changes when rebuilding the project

3. I also believe that recompiling that generates new output triggers a
second rebuild: the new .class files make AJDT think something changed. I
find that if I do a rebuild that creates a class file, then refresh the
project it immediately kicks off another incremental build.

It would also be good to not regenerate crosscutting symbols unless there
were changes in an incremental AJDT build (that's where all the time is
taken).

The Event Trace view with all categories turned on might offer some clues.
Presumably you perform some action which triggers a build? If it's not
the saving of a file, what is it?
