我已经使用 spring roo 1.2.3 提供的 multimodule.roo 建立了一个项目。

但是，当我运行“mvn tomcat:run”时，会出现以下错误：

Missing:
----------
1) com.example.petclinic:core:jar:0.1.0.BUILD-SNAPSHOT

  Try downloading the file manually from the project website.

  Then, install it using the command: 
      mvn install:install-file -DgroupId=com.example.petclinic -DartifactId=core -Dversion=0.1.0.BUILD-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file

  Alternatively, if you host your own repository you can deploy the file there: 
      mvn deploy:deploy-file -DgroupId=com.example.petclinic -DartifactId=core -Dversion=0.1.0.BUILD-SNAPSHOT -Dpackaging=jar -Dfile=/path/to/file -Durl=[url] -DrepositoryId=[id]

  Path to dependency: 
    1) com.example.petclinic.ui.mvc:mvc:war:0.1.0.BUILD-SNAPSHOT
    2) com.example.petclinic:core:jar:0.1.0.BUILD-SNAPSHOT

----------
1 required artifact is missing.

for artifact: 
  com.example.petclinic.ui.mvc:mvc:war:0.1.0.BUILD-SNAPSHOT

from the specified remote repositories:
  spring-maven-milestone (http://maven.springframework.org/milestone),
  central (http://repo1.maven.org/maven2),
  spring-roo-repository (http://spring-roo-repository.springsource.org/release),
  spring-maven-release (http://maven.springframework.org/release)

这是我的根 pom.xml 的一部分

<modules>
        <module>core</module>
    <module>ui</module>
    </modules>

现在，在 ui 模块中，还有另一个名为 mvc 的模块，其 pom.xml 包含：

<dependency>
            <groupId>com.example.petclinic</groupId>
            <artifactId>core</artifactId>
            <version>0.1.0.BUILD-SNAPSHOT</version>
        </dependency>

核心模块的包装是jar。

现在，据我了解，Maven 正试图在偏远地区定位本地工件“核心”。这就是为什么它得到这个错误。

如何防止 maven 在偏远地区搜索这个本地工件？还是我遇到了其他问题？

RE：我找到了一篇很棒的博客文章，我的问题似乎已经消失了

尝试通过运行 mvc 模块时遇到同样的错误

mvn jetty:run

我得到的错误是

找不到工件 com.example.petclinic:core:jar:0.1.0.BUILD-SNAPSHOT

问题是我没有在我的 Maven 存储库中安装工件核心。所以我回到了项目根目录和一个简单的

mvn install

安装了工件。

之后，我能够启动码头服务器。
