mvn clean install 无法解析 class

Question

我有以下maven结构

parent POM.XML
 - common/pom.xml
 - search/pom.xml

当我在 search 模块上执行 mvn clean install 时，搜索模块无法获取 common 模块类我得到 package de.test.common does not exists。我什至在父平台上运行 mvn clean install 但没有成功。 common 模块正在构建中。

我想我遇到了这里提到的同样问题

maven compilation failure

找到问题但未找到原因

我把下面的依赖去掉就一切OK了

          <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>

删除插件后，jar 以不同的结构构建。当 spring 启动插件在那里时，整个内容都在 BOOT-INF 文件夹中，我认为这是原因，但不确定...在这里需要专家意见。

Answer 1

解决这个问题的最简单方法是通过所谓的反应器项目，您可以在其中使用父 pom.xml 构建所有依赖模块。为此，将以下代码添加到您的父 POM 中：

<modules>
  <module>common</module>
  <module>search</module>
</modules>

现在，构建父 pPOM，您的整个构建应该可以正常工作。另外，不要在子项目中使用显式版本，只从父 POM 继承版本（我认为你在那里很好）。如果您引用来自同一项目反应器的依赖项，请使用版本 ${project.version}.

找到解决方案。可能有人会发现它有用。

<build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <classifier>exec</classifier>
                </configuration>
            </plugin>
        </plugins>
    </build>
