在没有根项目的情况下，如何在Maven3中执行反应堆构建? [英] How do you perform a reactor build in Maven3 without a root project?

问题描述

在没有根项目的情况下，如何在多个Maven项目上执行临时反应堆?

How does one perform an ad-hoc reactor build over multiple maven projects without a root project?

过去在maven2中可以通过使用带有-r选项的mvn命令来实现，该选项将从工作目录中递归搜索项目，并在反应堆中组织它们以正确的顺序进行构建，即使项目没有共享一个共同的父pom.xml.可以选择使用maven.reactor.includes和maven.reactor.excludes选项专门包括或排除某些项目.

This used to be possible in maven2 by invoking the mvn command with the '-r' option which would search recursively from the working directory for projects and organize them in the reactor to build in the correct order even if the projects did not share a common parent pom.xml. Optionally one could specifically include or exclude certain projects using maven.reactor.includes and maven.reactor.excludes option.

我意识到从maven3中删除了传统的反应堆模式，但是我不知道如何使用类似make"的反应堆模式来实现此功能.

I realize that the legacy reactor mode was removed from maven3 but I can't figure out how to achieve this functionality using the 'make-like' reactor mode.

推荐答案

在 MNG-4260 .

The "Maven 2"-style reactor feature has been removed following this discussion on the mailing list. The relevant JIRA issue is MNG-4260.

如上面的评论所述，最好使用<modules>部分创建一个顶级pom，其中列出了包含项目的目录. (如果您不总是同时构建所有项目，则可以在配置文件中放置单独的modules部分.)

As mentioned in the comments above, it's best to create a top-level pom with a <modules> section that lists the directories containing projects. (If you don't always build all of your projects at the same time, you can put separate modules sections in profiles).
