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

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
