创建的原型没有在包下创建文件夹

Question

使用 Apache Maven 3.8.2 (ea98e05a04480131370aa0c110b8c54cf726c06f)

项目结构如下：

My-archetype
| -- pom.xml
`--src
  `--main
    `resources
      |-- META-INF
         `--maven
             `--archetype-metadata.xml
       |--archetype-resources
          |--pom.xml
          |--log4j2.xml
          `--src
             |--main
             |   `--java
             |       `--App.java
             |        `--conf 

注意：conf 是一个目录

项目pom是

    <project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
https://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>demo</groupId>
  <artifactId>my-archetype</artifactId>
  <version>1</version>
  <packaging>maven-archetype</packaging>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
  </properties>

  <build>
    <extensions>
      <extension>
        <groupId>org.apache.maven.archetype</groupId>
        <artifactId>archetype-packaging</artifactId>
        <version>3.1.1</version>
      </extension>
    </extensions>
  </build>
</project>

archetype-metadata.xml 是：

<?xml version="1.0" encoding="UTF-8"?>
<archetype-descriptor
xsi:schemaLocation="https://maven.apache.org/plugins/maven-archetype-plugin/
archetype-descriptor/1.1.0
http://maven.apache.org/xsd/archetype-descriptor-1.1.0.xsd" name="at"
xmlns="https://maven.apache.org/plugins/maven-archetype-plugin/archetype-des
criptor/1.1.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <fileSets>
    <fileSet filtered="true" encoding="UTF-8">
      <directory></directory>
      <includes>
        <include>changeme.gitignore</include>
        <include>log4j2.xml</include>
      </includes>
    </fileSet>
    <fileSet filtered="false" packaged="true" encoding="UTF-8">
      <directory>src/main/java</directory>
      <includes>
      <include>**/*.java</include>
      </includes>
    </fileSet>
    <fileSet filtered="false" packaged="false" encoding="UTF-8">
      <directory>toplevel</directory>
    </fileSet>
  </fileSets>
</archetype-descriptor>

当我构建项目时，我 (mvn install) 有一条警告消息： [警告] 没有 Archetype IT 项目：找不到根“项目”目录。

我在 windows 10 环境下批处理文件是：

mvn archetype:generate "-DarchetypeGroupId=demo"
"-DarchetypeArtifactId=my-archetype" "-DarchetypeVersion=1" "-DgroupId=demo"
"-DartifactId=at" "-Dpackage=d" "-Dversion=0.0.1-SNAPSHOT"
"-DinteractiveMode=false"

输出是：

\toplevel 的目录已创建

在\src\main\java\d 的目录被创建，文件App.java 被创建 并且包名正确放置在文件中。

问题是根本没有创建目录 conf。我期待 它在 在\src\main\java\d\conf

但它没有被创建。我做错了什么？

我确实注意到了一件事 .. 如果我放置一个像 delme.txt 这样的文件并添加 **/*.txt 到 archetype-metadata 文件夹和文件是 创建的。但是我只想要一个空文件夹。

Answer 1

我有一个创建空目录的原型。我没有在archetype-resources/src/main 中指定该目录。相反，我将它放在META-INF/maven/archetype-metadata.xml 中，如下所示：

<fileSets>
    <fileSet filtered="true" encoding="UTF-8">
        <directory>src/main/scripts</directory>
    </fileSet>
</fileSets>

在使用原型后，我得到了一个空目录，正如预期的那样。
