Question

我目前正在使用Maven 3.3.3，已删除mvn.bat文件。现在，推荐的唯一运行Maven的方法是通过mvn.cmd文件。

我正在使用一个自定义原型来调用maven-invoker插件进行某些操作。 Note that the invoker plugin is a dependency of the Maven archetype plugin。

在archetype:generate上，调用调用者并抛出错误：

Error configuring command-line. Reason: Maven executable not found at: <MAVEN_PATH>\bin\mvn.bat

此问题似乎已在调用者的2.2版本中修复，但maven-archetype-plugin的最新版本仍然使用旧版本。

如何在我的原型POM中指定要使用的调用程序插件的版本？

目前，我已尝试通过将此代码添加到原型的POM文件中来配置插件，但它没有效果，并且没有修复错误。

<plugin>
    <groupId>org.apache.maven.archetype</groupId>
    <artifactId>maven-archetype</artifactId>
    <version>2.4</version>
    <dependencies>
        <dependency>
            <groupId>org.apache.maven.shared</groupId>
            <artifactId>maven-invoker</artifactId>
            <version>2.2</version>
        </dependency>
    </dependencies>
</plugin>

Answer 1

这是Maven Archetype插件的错误：JIRA问题是ARCHETYPE-488。它会影响插件的所有版本≤2.4并使用3.0.0版解析。

在链接问题中引用Jörg Hohwiller（日期为2016年1月8日13:47）：

是否有解决方法？


是的。只需创建一个“mvn.cmd”的副本，在MAVEN_HOME / bin中调用“mvn.bat”。

因此，2.4或更早版本的可能解决方法就是使用其他名称复制mvn可执行文件。

Answer 2

@Tunaki引用的错误已修复（发布以供参考）和pom.xml需求：

<plugin>
    <artifactId>maven-archetype-plugin</artifactId>
     <version>2.4</version>
     <dependencies>
     <dependency>
          <groupId>org.apache.maven.shared</groupId>
          <artifactId>maven-invoker</artifactId>
          <version>2.2</version>
     </dependency>
     </dependencies>
</plugin>

为Maven Archetype插件指定依赖项版本
