Question

我使用mvn clean package编译项目，但package does not exist失败。

详细命令：

通过在源项目中运行target/xxxx.jar来获取jar文件mvn clean package。
运行mvn install:install-file -Dfile=lib/xxxx.jar -DgroupId=com.company -DartifactId=source-package-name -Dversion=1.0.0 -Dpackaging=jar
将代码添加到目标项目，该项目将使用源项目中的一些功能
通过运行mvn clean package来编译目标项目，它刚刚以package does not exist

这是源项目pom.xml

理想情况下，不应将Spring Boot应用程序（已重新打包的东西）用作依赖项。来自the documentation：

与war文件类似，Spring Boot应用程序不能用作依赖项。如果您的应用程序包含要与其他项目共享的类，建议的方法是将该代码移动到单独的模块中。然后，您的应用程序和其他项目可以依赖单独的模块。

如果在您的情况下无法提出建议的解决方案，那么文档将继续描述替代方案：

如果您无法按照上面的建议重新安排代码，则必须配置Spring Boot的Maven和Gradle插件，以生成适合用作依赖项的单独工件。可执行存档不能用作依赖项，因为可执行jar格式打包BOOT-INF / classes中的应用程序类。这意味着当可执行jar用作依赖项时，无法找到它们。

要生成两个工件，一个可以用作依赖项，另一个可执行，必须指定一个分类器。此分类器应用于可执行归档的名称，保留默认归档以用作依赖项。

要在Maven中配置exec的分类器，可以使用以下配置：
<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
            <configuration>
                <classifier>exec</classifier>
            </configuration>
        </plugin>
    </plugins>
</build>

spring boot包不存在错误
