Maven不清理子项目目标文件夹

我设置了一个示例项目,以了解当从父项目位置运行<?php namespace App\Support; use Illuminate\Pagination\LengthAwarePaginator; use Illuminate\Support\Collection as BaseCollection; class Collection extends BaseCollection { public function paginate($perPage, $total = null, $page = null, $pageName = 'page') { $page = $page ?: LengthAwarePaginator::resolveCurrentPage($pageName); return new LengthAwarePaginator( $this->forPage($page, $perPage), $total ?: $this->count(), $perPage, $page, [ 'path' => LengthAwarePaginator::resolveCurrentPath(), 'pageName' => $pageName, ] ); } } 时,maven中的clean插件如何清理子项目。我以某种方式看到maven删除了父项目的目标,而不是子项目的目标。这使我感到困惑。

这是我的项目结构:

现在项目中的Java代码很少-只是一个hello world项目。我将只显示POM文件。

父项目的POM:

mvn clean:clean

子项目的POM:

<?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">

          </configuration>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>
</project>

我只关注清洁插件,而不关注其他任何东西。 因此,POM最小。我的问题是子pom无法清除目标文件夹是怎么回事?

我也在子项目的有效pom中显示<?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> <parent> <groupId>com.practice</groupId> <artifactId>learning-maven</artifactId> <version>1.0-SNAPSHOT</version> </parent> <artifactId>child-module1</artifactId> <version>1.0-SNAPSHOT</version> </project> 标签:

您必须在父POM中指定子模块,即:

<modules>
    <module>../child-module1</module>
</modules>

正如Arnaud所说,您需要在pom父级中添加子模块。您不需要路径,只需要artifactId

<modules>
    <module>child-module1</module>
</modules>
