After our warm-up release 0.7.0 M1, I have uploaded the second
milestone release to the Eclipse server. In contrast to the
cautionary words accompanying M1, the new Milestone 2 brings
the OTDT back to the maturity and quality it had before the
big move to Eclipse.org.

Milestone 2 passes a total of 49267 unit tests:
- 42654 JDT regression tests
- 6613 OT/J specific tests.

Milestone 2 is based on Eclipse SDK 3.6.0 M7 and should also
be compatible with other Eclipse Packages due today.

More on downloading/installing:
http://www.eclipse.org/objectteams/download.php

Migrating existing projects from OTDT 1.x to 0.7.x is supported
by a set of special errors & quickfixes. Read more at:
http://wiki.eclipse.org/OTHowtos/Migrating_Projects_To_0.7

Here is the list of issues resolved in Milestone 2:

310621 [compiler] should warn when after callin ignores return value of its role method
310995 [hierarchy] Support quick hierarchy for role methods
311201 [compiler] hasRole(Object, Class) call in inner teams ends up in NoSuchMethodError
311339 [dom] Quickfix "Add Return Statement" inserts invalid code
311432 [rewrite] Inferred callouts to private static fields make OrganizeImports to import private fields
308029 Automatically migrate OT-projects to new namespace
311109 nested teams must be specified using their internal name with "$__OT__"
311206 Adding InnerTeam for aspectBinding with the PDE Extension Editor results in wrong code

Happy downloading
Stephan

PS: Don't you think the OTDT could gather more than 20 votes
on the new Eclipse Marketplace so it would make it into the
top 10 list? Smile

When released OT/J command line compiler?

Thanks for asking, I actually forgot the command line compiler
when migrating the build process to Eclipse.org.

For now I have uploaded a snapshot to
http://download.eclipse.org/objectteams/ecotj/ecotj-I2010051 90940.jar

I should mention that this version already contains the
change from https://bugs.eclipse.org/310917
which changes the way precedences affect "after" callin bindings.

hope this helps, next build should again include a matching
command line compiler.

best,
Stephan

There is another problem. lombok Not working. Please refer to the following contents.

You mean you want to use the OT/J compiler together with lombok?
This will most certainly require some extra work.
Please file a bug (enhancement) for this issue.

From briefly browsing lombok I couldn't clearly see how it integrates into
the compile-and-run cycle. Do they
- replace / wrap the compiler?
- add an annotation processor?
- perform bytecode transformations (compile time / load time?)

With a basic understanding of lombok's working I could estimate how much
effort it would cost to support combining OT/J with lombok.

Lombok use annotation on build-time, like apt (http://java.sun.com/j2se/1.5.0/docs/guide/apt/).Run-time don't need lombok.jar.

Lombok use annotation : @Retention(RetentionPolicy.SOURCE). annotations are to be discarded by the compiler.

1 write source:
@setter private String myfiled;

2 compile(javac classpath: lombok.jar)
2.1auto generate source:
private String myfiled;
public void setMyfield(String myfiled){
this.myfield=myfield
}

2.2 generate bytecode class

in addition:
eclipse and javac compiler working properly

pinghe,
could you give some more info what exactly breaks when using lombok
together with the OTDT?

- Will lombok's annotation processor be invoked as it should?
(I couldn't find how that is configured)
- Does the annotation processor throw any exceptions?
- Does the annotation processor create any code? Is that code broken?

I also saw that lombok for Eclipse uses some very low level byte code transformations.
That may or may not conflict with OT/Equinox.

As I currently don't have the time to try it myself, I'd be grateful if you could
describe the problem a little more.

thanks,
Stephan

Hi again,

skimming through old messages, I found this issue unresolved:

http://www.ibm.com/developerworks/opensource/library/os-lomb ok/index.html

Is this still relevant?

If so I'd appreciate if you file a bug.
Thanks,
Stephan
