无法解析 Maven 多模块项目中的依赖项

Question

我发布了这个问题，尽管还有其他问题。但是，到目前为止我还没有找到任何解决方案，因此发布了这个问题。

我收到这个错误：

Could not resolve dependencies for project vehicle-tracker:vehicle-simulator:jar:0.0.1-SNAPSHOT: Failed to collect dependencies at vehicle-tracker:common-libs:jar:0.0.1-SNAPSHOT: Failed to read artifact descriptor for vehicle-tracker:common-libs:jar:0.0.1-SNAPSHOT: Could not find artifact vehicle-tracker:vehicle-tracker:pom:0.0.1-SNAPSHOT

common-libs jar 在

下可用

.m2\repository\vehicle-tracker\common-libs[=11=].0.1-SNAPSHOT

我试图构建的项目依赖于 common-libs jar，但在本地 maven 存储库中找不到 maven。

我正在关注POM.xml

我无法找到我在 POM 中做错的地方或其他地方......所以无法构建项目车辆跟踪器。

Answer 1

我解决了构建错误。实际上我是在下面 common-libs 模块的 POM.xml :

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

这应该在 commons-lib 模块的 POM.xml 中，因为它正在创建 spring-boot jar。因此，依赖项不适用于依赖模块。从 commons-lib 模块中删除 POM.xml 中的配置块后，我可以毫无问题地构建项目。

感谢大家的关注。如果有人有意或无意地面对这个问题，请分享这个。
