Plugin SCN Maven - Nie generowanie folderu OSGI-INF

Question

Mam problemy z uruchomieniem wtyczki SCR. Szukałem tyle, ile mogłem, tylko znalazłem przykłady, które nie były podobne do struktury, której mam użyć. Snippets of POMs below. Są to raczej wartości domyślne generowane przez archetyp projektu CQ. Istnieją wszystkie zależności, więc prawdopodobnie tak nie jest. Oto wyjściowy produkcji:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". 
SLF4J: Defaulting to no-operation (NOP) logger implementation 
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

Kluczową część produkcji jest [INFO] --- maven-scr-plugin:1.7.4:scr (generate-scr-descriptor) @ project-bundle ---. Wygląda na to, że nic nie generuje, mimo że adnotacje istnieją w klasie.

Każda pomoc jest bardzo doceniana.

Answer 1

Zgaduję używasz <packaging>bundle</packaging>, jeśli więc mam tej pracy poprzez modernizację maven-SCR-plugin do 1.9.0, z org.apache.felix.scr.annotations @ 1.7.0

Umieszczam tu plik wersji roboczej: https://dl.dropboxusercontent.com/u/2465717/com.stackoverflow.osgi.scr.tgz

Uwaga: można włączyć mapowanie cyklu życia Eclipse m2e - działa dobrze (Juno SR2), generując błędy komponentu SCR w normalnej konsoli problemów. Zmiana action <ignore/> do:

<action> 
     <execute> 
       <runOnIncremental>true</runOnIncremental> 
       <runOnConfiguration>true</runOnConfiguration> 
     </execute> 
</action> 

Również podczas spec wskazuje czas pracy SCR będą wyszukiwania dla przeciążonej de/aktywować metody - jak osobiste preferencje użyłbym @Activate, @Deactive i @Modified na odpowiednich metod, aby intent explicite (w kodzie i wygenerowany XML). Ale każdy do własnego.

Answer 2

sugeruję

• upgrade do najnowszej wersji maven-scr-plugin
• generować debug z -X, na przykład mvn -X compile

Answer 3

Ulepszono do wersji 1.9.0. Czy mówimy, że plugin v1.7.4 nie generuje deskryptorów. Dlaczego tak się dzieje, nie jest to główne zadanie dodatku do maven-scr-plug.
