Maven不会生成"persistence.xml"消息.文件 [英] Maven doesn't generate the "persistence.xml" file

问题描述

我阅读了本文在列出了不同目录布局的maven项目网页上(例如:src/main/resources用于应用程序/库资源).

I read this article on the maven project web page that lists the different directory layouts (like: src/main/resources which is for Application/Library resources).

问题是，当我运行以下命令时(在这里找到):

The problem is that when I run the following command (found here):

mvn archetype:generate -DgroupId=com.mycompany.app -DartifactId=my-app -DarchetypeArtifactId=maven-archetype-quickstart -DinteractiveMode=false

未创建src/main/resources/META-INF目录.这对我很重要，因为我想访问该目录中的"persistence.xml".

the src/main/resources/META-INF directory isn't created. It's important for me because I'd like to reach the "persistence.xml" that is found in that directory.

我应该在mvn命令中添加一个选项吗?如何自动生成包含"META-INF/persistence.xml"文件的"src/main/resources"?

Should I add an option in the mvn command? How can I automatically generate the "src/main/resources" that contains the "META-INF/persistence.xml" file?

谢谢你， 问候

问题是，当我运行以下命令(...)时，未创建src/main/resources/META-INF目录.这对我很重要，因为我想访问该目录中的"persistence.xml".

Maven快速入门原型不会创建src/main/resources或src/test/resources.有几种解释:

The maven quickstart archetype does NOT create src/main/resources nor src/test/resources. There are several explanations:

• 如其名称所述，此原型允许快速启动项目，具体取决于您的形状.
• 为什么这个原型应该创建src/main/resources而不能创建src/main/assembly?
• 长时间以来，实际上不可能创建空目录(请参阅 ARCHETYPE-57 ).

• As stated by its name, this archetype allows to quickstart a project, it's up to you to shape it.
• Why should this archetype create src/main/resources and not, say, src/main/assembly?
• Creating empty directories was actually not possible during a long time (see ARCHETYPE-57).

换句话说，如果使用此原型，只需手动添加src/main/resources/META-INF/persistence.xml.

In other words, just add src/main/resources/META-INF/persistence.xml manually if you use this archetype.

我应该在mvn命令中添加一个选项吗?如何自动生成包含"META-INF/persistence.xml"文件的"src/main/resources"?

Should I add an option in the mvn command? How can I automatically generate the "src/main/resources" that contains the "META-INF/persistence.xml" file?

您不能拥有这种原型-我真的不明白为什么这是一个如此大的问题.

You can't with this archetype - and I don't really understand why this is a such big issue.

虽然有一个JPA原型:

There is a JPA archetype though:

mvn archetype:create \
  -DgroupId=com.mycompany.project \
  -DartifactId=my-project-domain \
  -DpackageName=com.company.project.domain \
  -DarchetypeGroupId=com.rfc.maven.archetypes \
  -DarchetypeArtifactId=jpa-maven-archetype  \
  -DarchetypeVersion=1.0.0  \
  -DremoteRepositories=http://maven.rodcoffin.com/repo

这将创建以下引导JPA项目:

That creates the following bootstrap JPA project:

$ tree my-project-domain/
my-project-domain/
├── pom.xml
└── src
    ├── main
    │   ├── java
    │   │   └── com
    │   │       └── company
    │   │           └── project
    │   │               └── domain
    │   │                   └── User.java
    │   └── resources
    │       └── META-INF
    │           └── persistence.xml
    └── test
        ├── java
        │   └── com
        │       └── company
        │           └── project
        │               └── domain
        │                   ├── DbUnitDataLoader.java
        │                   └── UserTest.java
        └── resources
            └── user.db.xml
