我有一个多模块的项目与maven和Spring Boot 。
我的主pom.xml：

<?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">

        <relativePath/>
    </parent>

    <artifactId>kazi</artifactId>
    <version>0.1-SNAPSHOT</version>
    <packaging>pom</packaging>

    <modules>
        <module>kazi-core</module>
        <module>kazi-api</module>
        <module>kazi-service</module>
    </modules>

        <dependency>

            <configuration>
                <mainClass>com.kazi.Application</mainClass>
            </configuration>
        </plugin>
      </plugins>
    </build>
</project>

依赖于另一个模块的第一个模块导致生成失败：

[INFO] kazi ............................................... SUCCESS [  2.186 s]
[INFO] kazi-core .......................................... SUCCESS [  4.640 s]
[INFO] kazi-api ........................................... FAILURE [  1.415 s]

kazi-core是与另一个模块没有相关性的模块，kazi-api与kazi-core具有相关性，kazi-service与kazi-api具有相关性

当a跳过spring-boot-maven-plugin时，它工作正常：

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

我的Application.class主类在核心模块中。
如何在多模块项目中使用spring-boot-maven-plugin。

只在有主类的模块中使用spring-boot-maven-plugin。不要在库模块中使用该插件。
显示当前行为：当您在父pom文件中使用插件时，您将自动为每个嵌套模块应用此插件步骤。

我也遇到过类似的问题，它帮我解决了。
1.只在包含主类的模块中保留spring-boot-maven-plugin。从所有其他模块中删除它。
1.更新spring-boot-maven插件中的可执行文件配置，如下所示。

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