Question

我创建了一个具有以下结构

的多模块maven项目

我打算将RestService（我计划保留我的控制器的模块）部署为战争，将所有其他模块部署为jar。

请找到下面的poms：

            </plugin>
        </plugins>
    </build>


</project>

RestService：

<?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"

        <version>1.0.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>RestService</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <packaging>war</packaging>

    <dependencies>
        <dependency>
            <groupId>com.myproject</groupId>
            <artifactId>CacheEngine</artifactId>
            <version>1.0.0-SNAPSHOT</version>
        </dependency>
    </dependencies>

</project>

CacheEngine：

<?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">
    <parent>
        <artifactId>MyProject</artifactId>
        <groupId>com.myproject</groupId>
        <version>1.0.0-SNAPSHOT</version>
    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>CacheEngine</artifactId>
    <packaging>jar</packaging>
    <version>1.0.0-SNAPSHOT</version>

</project>

类似于其他模块。

当我尝试使用mvn clean install -DskipTests

进行构建时

它给我一个错误，说明在CacheEngineModule

中找不到主类

移动部分

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

到要构建为可执行文件的模块的pom。（在你的情况下可能是RestService pom）。当它位于项目的父pom中时，spring-boot-maven-plugin将尝试从每个子模块生成一个可执行jar。
