Maven执行计划

Question

我有一个很长的构建，其中包含许多步骤、插件和执行，这些步骤、插件和执行配置在大约 30 个 pom 中，属于一个复杂的模块化项目。由于构建花费了太多（2h），我想对其进行一些简化，为此我希望 maven 列出它在不执行它的情况下会经历的所有步骤。比如：

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

[INFO] ------------------------------------------------------------------------
[INFO] Building Main Project
[INFO] ------------------------------------------------------------------------
[INFO]

[INFO] 
[INFO]                                                                         
[INFO] ------------------------------------------------------------------------
[INFO] Building Module#1
[INFO] ------------------------------------------------------------------------
[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] ------------------------------------------------------------------------

有没有什么方法可以在不挖掘几兆的日志文件的情况下获得这些信息？

由于显然没有 OOTB 方法可以做到这一点，我最终写了 plan-maven-plugin。它允许您展开提供goals 参数的计划：

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

或将其作为正常构建的一部分执行：

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

样本输出：

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