maven-2 - mvn 全新安装、部署、发布

Question

我刚刚学习maven，最近需要走的越来越多。我想知道两者的区别

mvn 全新安装

mvn 发布

mvn 部署

请尽可能具有描述性。

Answer 1

clean、install 和 deploy 阶段有效 lifecycle phases调用它们将触发它们之前的所有阶段，以及与这些阶段绑定(bind)的目标。

mvn clean install

此命令依次调用clean 阶段和install 阶段:

• clean:删除项目目录中构建时生成的文件(默认为target)
• 安装:将包安装到本地存储库中，以用作本地其他项目的依赖项。

mvn deploy

此命令调用部署阶段:

• 部署:将最终包复制到远程存储库，以便与其他开发人员和项目共享。

mvn release

这不是一个有效的阶段，也不是一个目标，所以这不会做任何事情。但如果指的是Maven Release Plugin用于自动化发布管理。发布项目分两步完成:准备和执行。据记录:

Preparing a release goes through the following release phases:

• Check that there are no uncommitted changes in the sources
• Check that there are no SNAPSHOT dependencies
• Change the version in the POMs from x-SNAPSHOT to a new version (you will be prompted for the versions to use)
• Transform the SCM information in the POM to include the final destination of the tag
• Run the project tests against the modified POMs to confirm everything is in working order
• Commit the modified POMs
• Tag the code in the SCM with a version name (this will be prompted for)
• Bump the version in the POMs to a new value y-SNAPSHOT (these values will also be prompted for)
• Commit the modified POMs

然后:

Performing a release runs the following release phases:

• Checkout from an SCM URL with optional tag
• Run the predefined Maven goals to release the project (by default, deploy site-deploy)
