<div>Hi all,</div>
<div><br>
</div>
<div>Our team, made of various Eclipse JDT contributors, is
currently looking at allowing Eclipse JDT to directly use
Javac instead of ECJ for Java code parsing and resolution
and code generation. The goal is to keep the higher levels
of Eclipse JDT and its ecosystem/plugins working, and allow
to plug a Javac-based backend under the hood as an
alternative.<br>
</div>
<div>We've already made significant progress on this topic,
and despite various remaining glitches, a proof of concept
is already kind of usable, with all typical IDE features
(code analysis, error reporting, selection, completion,
indexing...) provided by javac backend. We are then
confident that this is a viable approach on the mid to long
term.</div>
<div>Ongoing work is happening at <a href="https://github.com/eclipse-jdtls/eclipse-jdt-core-incubator" moz-do-not-send="true" class="moz-txt-link-freetext">https://github.com/eclipse-jdtls/eclipse-jdt-core-incubator</a></div>
<div><br>
</div>
<div>While working on it, we've identified some interesting
features of ECJ that are missing in Javac and that would be
in our opinion extremely profitable to IDE integration, but
also could be profitable to other integrations as they can
shorten the feedback look tremendously in some cases.<br>
</div>
<div>The main feature we're missing from ECJ would be
something equivalent to its `-proceedOnError` flag.
Basically, it makes that the compiler, when it faces a
compilation error, replaces the DOM/AST and the generated
code with `throw new
CompilationError(compilationErrorMessage)`. This is
extremely convenient when debugging as it allows to hotswap
some not-yet-complete-but-already-interesting-to-debug code
into a running application.</div>
<div>Do you think Javac could some day provide such a feature
too? This is not (yet?) a request for enhancement, at this
stage, we're just evaluating our hopes of getting our
integration supporting this important enough case in the
future. If there is no technical reason why not, then we may
investigate contributing it (of course, if someone wants to
implement it in the meantime, don't hesitate in coding it
before us ;)</div>

<div>Cheers,<br>
