Piano di esecuzione Maven

Question

Ho una lunga build con numerosi passaggi, plugin ed esecuzioni configurati in circa 30 poms appartenenti a un complesso progetto modulare. Dato che la build sta prendendo troppo (2h) mi piacerebbe razionalizzarlo un po ', per il quale mi piacerebbe che Maven mi elencasse tutti i passi che avrebbe compiuto senza eseguirlo. Qualcosa di simile:

$ mvn --dry-run clean 
[INFO] Reactor Build Order: 
[INFO] 
[INFO] Main project 
[INFO] Module#1 
[INFO] Module#2 
[..]

[INFO] 
[INFO] --- maven-clean-plugin:2.4.1:clean (default-clean) @ module1 --- 
[INFO] 
[INFO] ------------------------------------------------------------------------ 
[INFO] BUILD SUCCESS 
[INFO] ------------------------------------------------------------------------ 
[INFO] Total time: 0:01.020s 
[INFO] Finished at: Thu Apr 26 09:56:14 CEST 2012 
[INFO] Final Memory: 198M/379M 
[INFO] ------------------------------------------------------------------------ 

C'è un modo per avere queste informazioni senza di me scavare in un paio di mega di un file di log?

Answer 1

Poiché non c'è apparentemente alcun modo OOTB per farlo, ho finito per scrivere il plan-maven-plugin. Esso consente di srotolare il piano che fornisce il parametro goals:

mvn plan:plan -Dgoals=clean,javadoc:jar,sources:jar,package,gpg:sign,install 

o di eseguirlo come parte della corporatura normale:

mvn plan:plan clean javadoc:jar sources:jar package gpg:sign install 

Esempio di output:

$ mvn plan:plan clean javadoc:javadoc package install site:site
