I am developing a project in maven, and I have created 2 modules, one for the entities
Here the pom.xml

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;project xmlns=&quot;http://maven.apache.org/POM/4.0.0&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;
xsi:schemaLocation=&quot;http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd&quot;&gt;
&lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
&lt;parent&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-parent&lt;/artifactId&gt;
&lt;version&gt;2.3.1.RELEASE&lt;/version&gt;
&lt;relativePath/&gt; &lt;!-- lookup parent from repository --&gt;
&lt;/parent&gt;
&lt;groupId&gt;com.fakenews.commons&lt;/groupId&gt;
&lt;artifactId&gt;fakenewsCommons&lt;/artifactId&gt;
&lt;version&gt;0.0.4-SNAPSHOT&lt;/version&gt;
&lt;name&gt;fakenewsCommons&lt;/name&gt;
&lt;description&gt;Demo project for Spring Boot&lt;/description&gt;
&lt;properties&gt;
&lt;java.version&gt;11&lt;/java.version&gt;
&lt;/properties&gt;
&lt;dependencies&gt;
&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-data-jpa&lt;/artifactId&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-test&lt;/artifactId&gt;
&lt;scope&gt;test&lt;/scope&gt;
&lt;exclusions&gt;
&lt;exclusion&gt;
&lt;groupId&gt;org.junit.vintage&lt;/groupId&gt;
&lt;artifactId&gt;junit-vintage-engine&lt;/artifactId&gt;
&lt;/exclusion&gt;
&lt;/exclusions&gt;
&lt;/dependency&gt;
&lt;/dependencies&gt;
&lt;build&gt;
&lt;plugins&gt;
&lt;plugin&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
&lt;/plugin&gt;
&lt;/plugins&gt;
&lt;/build&gt;
&lt;/project&gt;

And the other module makes use of this one through dependencies in the pom

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;project xmlns=&quot;http://maven.apache.org/POM/4.0.0&quot; xmlns:xsi=&quot;http://www.w3.org/2001/XMLSchema-instance&quot;
xsi:schemaLocation=&quot;http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd&quot;&gt;
&lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt;
&lt;parent&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-parent&lt;/artifactId&gt;
&lt;version&gt;2.3.3.RELEASE&lt;/version&gt;
&lt;relativePath/&gt; &lt;!-- lookup parent from repository --&gt;
&lt;/parent&gt;
&lt;groupId&gt;com.fakenews.scraper.api&lt;/groupId&gt;
&lt;artifactId&gt;fakenewsScraperApi&lt;/artifactId&gt;
&lt;version&gt;0.0.4-SNAPSHOT&lt;/version&gt;
&lt;name&gt;fakenewsScraperApi&lt;/name&gt;
&lt;description&gt;Demo project for Spring Boot&lt;/description&gt;
&lt;properties&gt;
&lt;java.version&gt;11&lt;/java.version&gt;
&lt;/properties&gt;
&lt;dependencies&gt;
&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-data-jpa&lt;/artifactId&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-web&lt;/artifactId&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
&lt;groupId&gt;com.fakenews.commons&lt;/groupId&gt;
&lt;artifactId&gt;fakenewsCommons&lt;/artifactId&gt;
&lt;version&gt;0.0.4-SNAPSHOT&lt;/version&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-devtools&lt;/artifactId&gt;
&lt;scope&gt;runtime&lt;/scope&gt;
&lt;optional&gt;true&lt;/optional&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
&lt;groupId&gt;mysql&lt;/groupId&gt;
&lt;artifactId&gt;mysql-connector-java&lt;/artifactId&gt;
&lt;scope&gt;runtime&lt;/scope&gt;
&lt;/dependency&gt;
&lt;dependency&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-starter-test&lt;/artifactId&gt;
&lt;scope&gt;test&lt;/scope&gt;
&lt;exclusions&gt;
&lt;exclusion&gt;
&lt;groupId&gt;org.junit.vintage&lt;/groupId&gt;
&lt;artifactId&gt;junit-vintage-engine&lt;/artifactId&gt;
&lt;/exclusion&gt;
&lt;/exclusions&gt;
&lt;/dependency&gt;
&lt;/dependencies&gt;
&lt;build&gt;
&lt;plugins&gt;
&lt;plugin&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
&lt;/plugin&gt;
&lt;/plugins&gt;
&lt;/build&gt;
&lt;/project&gt;

I have already compiled the first module with the entities with

> mvn clean install

and I have verified that:

  1. the .jar has been created in the folder ~ / .m2 / repository / com / fakenews / commons / fakenewsCommons / 0.0.4-SNAPSHOT

Maven找不到包。

  1. I have decompiled the jar to check that the classes are there
    Maven找不到包。

but when i compile the main module with

> mvn clean install

maven can't find the package.

<<<<<< EDIT

I use IntelliJ and the maven module of IntelliJ Ommited the Spring-boot-starter-jpa , i don't know if it's normal.
Maven找不到包。

答案1

得分: 4

我的解决方案在这里：
https://www.baeldung.com/spring-boot-dependency

或者您可以只删除以下部分：

&lt;build&gt;
&lt;plugins&gt;
&lt;plugin&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
&lt;/plugin&gt;
&lt;/plugins&gt;
&lt;/build&gt;

在 spring-boot 项目中作为一个依赖。

英文:

My solution is here :
https://www.baeldung.com/spring-boot-dependency

or you can just delete

&lt;build&gt;
&lt;plugins&gt;
&lt;plugin&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
&lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
&lt;/plugin&gt;
&lt;/plugins&gt;
&lt;/build&gt;

On the spring-boot project as a dependency

答案2

得分: 2

据我所知，如果您使用父级 spring-boot-starter-parent 构建了一个 JAR 文件，您将无法将其用作依赖项。

英文:

AFAIK, you cannot use a jar as dependency if you build it with the parent spring-boot-starter-parent.

答案3

得分: 1

在我看来，问题出现在您的父级pom中，您应该创建一个类似于以下项目结构

application => pom.xml
- common => pom.xml
- API => pom.xml
  1. 在 application => pom.xml 中，创建一个打包为pom的模块，添加模块 common 和 api。您可能需要添加一个父级来扩展Spring Boot。别忘了添加 dependencyManagement。
  2. 在 common => pom.xml 中，创建一个打包为jar的模块，父级为 application。您可以添加用于 common 模块的依赖。
  3. 在 API => pom.xml 中，创建一个打包为jar的模块，父级为 application。您可以在这里添加 Spring JPA 依赖。
    然后将 common 作为共享库引入，与您之前的操作相同。
英文:

IMO, the problem come from your parent pom, you should create a project structure like

application =&gt; pom.xml
- common =&gt; pom.xml
- API =&gt; pom.xml
  1. application => pom.xml package pom, add modules common, api. you may add a parent to extend spring boot. Dont forget add dependencyManagement
  2. common => pom.xml package jar, parent = application. you can add dependency which used for common
  3. API => pom.xml package jar, parent = application. You can add spring JPA dependencies here
    then enjoin you common as a shared library same as what you did

答案4

得分: 1

这样做会更好，如果你创建一个父级 pom.xml，并将 commons 项目作为一个模块添加进去。
这样你可以在父级 pom 中使用公共依赖，而各个模块也可以使用它们。

英文:

It is much better if you create a parent pom.xml and add the commons project as a module.
So you can use the common dependencies in the parent pom and the modules can use them.
