Maven Compile failed, cannot find symbol-CodePudding

I don't know how to set `ref-model` as a dependency of other-service...

below is part of my code, and you can also get it in my source code

Constant class in web-common-enums

package com.wwstation.common.constants;

import lombok.AllArgsConstructor;
import lombok.Getter;

/**
 * 常量值
 *
 * @author william
 * @description
 * @Date: 2021-02-17 11:56
 */
@Getter
@AllArgsConstructor
public class Constants {
    public static final String commonString="commonString";
}

a simple class in ref-model

package com.wwstation.common;

import com.wwstation.common.constants.Constants;

/**
 * @author william
 * @description
 * @Date: 2022-01-28 12:04
 */
public class TestClass {
    public static void test() {
        System.out.println(Constants.commonString);
    }
}

main class in other-service

package com.wwstation.other_service;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

/**
 * @author william
 * @description
 * @Date: 2022-01-28 14:09
 */
@SpringBootApplication(scanBasePackages = {"com.wwstation","com.wwstation.common"})
public class OtherServiceApplication {
    public static void main(String[] args) {
        SpringApplication.run(OtherServiceApplication.class, args);
    }
}

test component in other-service

package com.wwstation.other_service.components;


import com.wwstation.common.TestClass;
import org.springframework.stereotype.Component;

import javax.annotation.PostConstruct;

/**
 * @author william
 * @description
 * @Date: 2022-01-28 14:12
 */
@Component
public class TestComponent {

    @PostConstruct
    public void initAndPrint() {
        TestClass.test();
    }
}

And this is the error console:

CodePudding user response：

I removed the relationship between 'web-common' module and 'web-common-enums' module on pom.xml file:

<?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">
<groupId>com.wwstation</groupId>
<modelVersion>4.0.0</modelVersion>
<version>1.0-SNAPSHOT</version>
<artifactId>web-common-enums</artifactId>
</project>

located in '${root}/web-common/web-common-enums/pom.xml'.

Secondly, execute

mvn install

on web-common-enums module.

Finally, execute

mvn compile

on ref-model module. It worked.

OMG! just remove all the plugins in web-common and it's child modules.....
