maven - Maven执行计划

Question

我有一个很长的构建，其中包含大量步骤、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 列出我在不执行它的情况下会经历的所有步骤。就像是：

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

有没有办法在我不挖掘几兆的日志文件的情况下获得这样的信息？

由于显然没有 OOTB 方法可以做到这一点，我最终编写了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
