我有三个Maven项目,一个是pom软件包,另外两个是jar包装,这里是admin-aggreagator pom

并且我没有得到admin-rest pom.xml及其主类,因为ctrl-click导航到相应的项目并且类型搜索可以在admin-rest中找到主类项目ctrl + shift + T也变得静止不动,

主类AdminRestApp.java,我正在尝试使用
运行admin-aggregatormvn clean spring-boot:run
mvnw.cmd clean spring-boot:run
./mvnw spring-boot:run
但没有一个起作用
package com.sounds.bvs;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class AdminRestApp {
public static void main(String[] args) {
SpringApplication.run(AdminRestApp.class, args);
}
}
and the exception i see class not found exception i tried all which were from similar topic none helped, the start-class tag is also place and hard code the full path com.sounds.bvs.AdminRestApp in mainClass still that also did not help,
我已经尝试过更改Spring Boot版本以及Mint编译器插件版本,这也帮助了我们,请非常需要。
之前的软件包路径是大的com.sounds.bvs.admin.rest,那时候同样的问题更改了软件包名称,这对dint也有帮助
请提前让我知道我想念的东西。

添加 spring boot 版本解决了我的问题。
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<version>2.4.1</version>
</plugin>
</plugins>
在 Maven Tab ->plugins 中替换为您的 spring boot 版本

对我有用。
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</pluginManagement>

答案 2 :(得分:0)
您必须从包含Spring Boot应用程序(mvn spring-boot:run
)的模块Maven中执行admin-rest
命令,而不是从父模块(admin-aggregator
)中执行。
但是您可以从父模块执行它。

我删除了.m2文件夹并重新安装pom.xml文件,问题已解决。
答案 4 :(得分:0)
我在这里https://docs.spring.io/spring-android/docs/2.0.0.M3/reference/html/maven.html读过。 然后点击链接:https://search.maven.org/-输入搜索内容:spring-boot-maven-plugin ..
得到我的依赖。 它对我有用。
