Errai 2.0 and compilation error

[superfis]

I develope a project with Errai 1.3.1-SNAPSHOT and today I've switched to 2.0-SNAPSHOT. This is a maven based project. During the building (maven build), I receive such error:

...

[INFO] INFO [RpcProxyLoaderGenerator] generating rpc proxy loader class.

[INFO]    [ERROR] Errors in 'd:\workspace371\dms\target\.generated\org\jboss\errai\marshalling\client\api\MarshallerFactoryImpl.java'

[INFO]       [ERROR] Line 1898: Unresolvable native reference to field 'suppressedExceptions' in type 'java.lang.Throwable'

[INFO]       [ERROR] Line 1902: Unresolvable native reference to field 'suppressedExceptions' in type 'java.lang.Throwable'

[INFO]    [ERROR] Cannot proceed due to previous errors

[INFO] ------------------------------------------------------------------------

[INFO] BUILD FAILURE

...

and below mentioned by compiler code snippets

-> org\jboss\errai\marshalling\client\api\MarshallerFactoryImpl.java:1898):

  private native static void java_lang_Throwable_suppressedExceptions(Throwable instance, List value) /*-{

    [e-mail]::suppressedExceptions = value;

  }-*/;

-> org\jboss\errai\marshalling\client\api\MarshallerFactoryImpl.java:1902):

  private native static List java_lang_Throwable_suppressedExceptions(Throwable instance) /*-{

    return [e-mail]::suppressedExceptions;

  }-*/;

Is there a way to avoid this compilation error?

What version of the JDK are you using?

[superfis]

C:\Users\slawek>java -version

java version "1.7.0"

Java(TM) SE Runtime Environment (build 1.7.0-b147)

Java HotSpot(TM) Client VM (build 21.0-b17, mixed mode, sharing)

Compilation of project with Errai 1.3.1-SNAPSHOT libs never finished with such error. I haven't change anything in my project except libs (changed to 2.0-SNAPSHOT) and after that the compilation error appeared.

Hi Mike,

Do you have any idea what I did wrong or what I can change to have 2.0-SNAPSHOT working? I really want to switch to newest Errai implementation.

We will be publishing new snapshots for 2.0 in about an hour which fix this problem.

Hi,

I tried it once again and this time I receive the error:

At first I thought that it was compiled under java jdk1.6 but the I removed old (not used) jdk1.6 and the only remaining java is jdk1.7 (and jre7) - unfortunatelly, the error still appears. What's wrong?

Can you try again after deleting the code generation cache (the .errai subdirectory)? Alternatively, you can pass -Derrai.devel.nocache=true as parameter to the build. This is only necessary after upgrading to a new version.

[superfis]

After I deleted .errai folder and added -Derrai.devel.nocache=true to the build, I receive the same kind of errors but a bit different locations for them in generated java source file:

[INFO] INFO [RpcProxyLoaderGenerator] generating rpc proxy loader class.

[INFO]    [ERROR] Errors in 'D:\workspace371\dms\target\.generated\org\jboss\errai\marshalling\client\api\MarshallerFactoryImpl.java'

Yes, we are still working through getting the new marshalling implemented. I believe the SNAPSHOT which will be going out in a few hours will fix this problem.

The latest changes you have made solved the problem and now the compilation finishes with no errors.
