Maven 自定义原型无法生成项目

Question

我正在尝试创建新的 Maven 原型来根据我的需要生成自定义项目。我的项目如下所示

我的原型 pom 如下所示：

<?xml version="1.0" encoding="UTF-8"?>
<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 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.tarkshala</groupId>
    <artifactId>maven-archetype-tarkshala-service-models</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>

    <name>tarkshala-service-models-archetype</name>

    <!-- Used to point local artifacts to the hosted repo , Starts  -->
    <distributionManagement>
        <repository>
            <id>nexus</id>
            <name>maven-releases</name>
            <url>http://maven.tarkshala.com:10081/repository/maven-releases/</url>
        </repository>
        <snapshotRepository>
            <id>nexus</id>
            <name>maven-snapshots</name>
            <url>http://maven.tarkshala.com:10081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>
    <!--  Ends  -->

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>18</source>
                    <target>18</target>
                    <compilerArgs>--enable-preview</compilerArgs>
                </configuration>
            </plugin>
        </plugins>
    </build>

    <!--    Check we can delete compiler properties-->
    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
    </properties>

</project>

我的 archetype.xml 如下所示

<archetype-descriptor xmlns="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-descriptor/1.0.0"
                      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
                      xsi:schemaLocation="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-descriptor/1.0.0 http://maven.apache.org/xsd/archetype-descriptor-1.0.0.xsd"
                      name="maven-archetype-sample" partial="false">

    <requiredProperties>
        <!-- This is used in pom.xml of the future app. -->
        <requiredProperty key="projectName">
            <defaultValue>TarkshalaService</defaultValue>
        </requiredProperty>
    </requiredProperties>


    <fileSets>
        <fileSet filtered="true" packaged="true">
            <directory>src/main/java</directory>
            <includes>
                <include>**/**.java</include>
            </includes>
        </fileSet>

        <fileSet filtered="true">
            <directory/>
            <includes>
                <include>*.yml</include>
                <include>.gitignore</include>
                <include>*.md</include>
                <include>*.xml</include>
            </includes>
        </fileSet>
    </fileSets>


</archetype-descriptor>

在原型上完成时，mvn clean install 成功，但 mvngenerate 失败，如下

~/W/r/maven-archetype-tarkshala-service-models (master|✚1) [1]$ mvn archetype:generate                                  \

有人可以帮忙指出我到底做错了什么吗？

我不知道你是否解决了这个问题，但也许对其他人有帮助。您必须将 archetype.xml 文件重命名为 archetype-metadata.xml。这就是为我解决的问题。
