Maven 原型:修改 artifactId [英] Maven archetype: Modify artifactId

问题描述

在做项目时，我的要求是创建一个模块.

While working on project, my requirement is to create a module.

命令如下:

mvn archetype:generate \
  -DarchetypeCatalog=local \
  -DartifactId=test-module

并且目标应该具有以下文件结构

And the target should have following file structure

test-module
|--pom.xml
`--src
   `--main
      |--install
      |  `--install.sh
      `--scripts
         `--test_module.sh

我的整个目标是创建另一个从 artifactId 派生的变量(比如 artifactIdWithUnderscore)，用 underscope _ 替换所有连字符 -.这样我就可以使用更新的变量来创建文件.

My whole goal is to create another variable derived from artifactId (say artifactIdWithUnderscore) replacing all hyphens - by underscope _. So that I can use the updated variable to create file(s).

示例:

+------------------+---------------------------------+
|INPUT - artifactId|OUTPUT - artifactIdWithUnderscore|
+------------------+---------------------------------+
|    test-module   |          test_module            |
|       temp       |             temp                |
| test-temp-module |       test_temp_module          |
+------------------+---------------------------------+

我尝试通过在 archetype-metadata.xml

选项 1:

<requiredProperty key="artifactIdWithUnderscore" >
  <defaultValue>${StringUtils.replace(${artifactId}, "-", "_")}</defaultValue>
</requiredProperty>

输出:

${StringUtils.replace(${artifactId}, "-", "_")}

选项 2:

<requiredProperty key="artifactIdWithUnderscore" >
  <defaultValue>${artifactId.replaceAll("-", "_")}</defaultValue>
</requiredProperty>

输出:

maven_archetype_script

上述 artifactId 的值来自于原型项目本身的 POM.

The above value of artifactId is coming from the POM of archetype project itself.

选项 3:

<requiredProperty key="artifactIdWithUnderscore" >
  <defaultValue>${artifactId}.replaceAll("-", "_")</defaultValue>
</requiredProperty>

输出:

test-module.replaceAll("-", "_")

请告诉我如何实现这一目标.

Please let me know how I can achieve this.

编辑:

选项 4:

<requiredProperty key="artifactIdWithUnderscore" >
    <defaultValue>${__artifactId__.replaceAll("-", "_")}</defaultValue>
</requiredProperty>

输出:

INFO: Null reference [template 'artifactIdWithUnderscore', line 1, column 1] : ${__artifactId__.replaceAll("-", "_")} cannot be resolved. 
Define value for property 'artifactIdWithUnderscore': ${__artifactId__.replaceAll("-", "_")}: :

推荐答案

选项 2 对我有用:

<requiredProperty key="artifactIdWithoutDash">
  <defaultValue>${artifactId.replaceAll("-", ".")}</defaultValue>
</requiredProperty>

我可以使用 __artifactIdWithoutDash__.sh 有一个文件名来创建文件(在我的例子中是:some.letters.__artifactIdWithoutDash__.cfg)

I can use __artifactIdWithoutDash__.sh has a file name to create the file (in my case it was: some.letters.__artifactIdWithoutDash__.cfg)
