maven - 有没有办法对原型(prototype)生成的项目进行后处理？

Question

假设我有一个原型(prototype)并从中生成一个项目。但是我想通过命令行传递占位符的值来解析我在生成时间之后生成的项目的属性文件中的占位符。

例如具有以下命令行:

mvn archetype:create -DarchetypeGroupId=... -DarchetypeArtifactId=... -DarchetypeVersion=1.0 -DgroupId=... -DartifactId=my-project -Dversion=1.0-SNAPSHOT -Dhello=你好!

假设原型(prototype)包含具有以下内容的 app.properties(作为正在生成的项目的一部分):

问候=${你好}

是否可以将 ${hello} 替换为“Hello!”在由于 mvn archetype:create 命令生成项目之后？

Answer 1

是的，这是可能的。来自 advanced usage guide对于 Maven 原型(prototype):

If the user wants to customize the generated project even further, a groovy script named archetype-post-generate.groovy can be added in src/main/resources/META-INF/. This script will end up in the generated archetype's META-INF folder and will be executed upon creating a project from this archetype. This groovy script has access to the ArchetypeGenerationRequest object, as well as all the System.getProperties() and all the archetype generation properties the user has specified.
