覆盖Maven中的原型

Question

我在使用Maven的原型时遇到了一些麻烦，因此我需要覆盖一些原型。我启动一个执行原型的指令：在原型已经存在的目录中生成。

是否有一个参数让我覆盖现有的原型？

我有搜索行家definitve指导，但它指出，唯一接受的参数是： -DgroupId -DartifactId -Dversion -DpackageName -DarchetypeGroupId -DarchetypeArtifactId -DarchetypeVersion -DinteractiveMode

我可以只搜索目录并删除文件，但这个过程会自动完成（所以没有人参与，不涉及大脑），我不希望他的机器删除周围的东西。

谢谢大家！

编辑：我差点忘了，这里是一些行家跟踪：

Answer 1

我猜你会检查出原型的来源。例如

http://svn.apache.org/viewvc/maven/archetype/tags/maven-archetype-quickstart-1.1

应用更改并运行mvn安装

这么说，你应该通常不会做进一步的参考这样

Answer 2

我想在重新生成时覆盖文件一个原型 - 类似于你的要求，用户可以用不同的参数重新生成一个项目。在我的情况下，我从模型生成一个完整的REST堆栈，当我对原型本身进行更改时，我想迭代地重新生成所有代码。

我想这样做的部分原因是让IntelliJ项目文件在regens之间保持完整 - 这样我就不必将生成的项目重新导入到IntelliJ中。

maven原型插件不会覆盖文件，也没有启用该选项的选项。

我找到的解决方案是删除生成的项目下的所有文件，除了IntelliJ.iml项目文件，并保留.idea和所有目录完好无损。然后，原型插件将工作。我从脚本中调用原型插件并在其中执行删除操作。如果“PP”是包含该项目重新生成目录的名称：

# This should leave IntelliJ project files intact accross regens. 
find pp -type d -name 'target' -exec rm -fR {} \; 
find pp -type d -name 'generated' -exec rm -fR {} \; 
find pp -type f -not -path '*/.idea/*' -not -name '*.iml' -exec rm {} \; 

您应该能够拿出一些这方面的变化，以达到你想要的东西。
