如何修改settings.xml，以便如果本地不存在依赖项，请从Internet获得它

Question

我已经使用maven 3.3来构建项目。在这里，我们使用本地Maven存储库。 这是settings.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<settings xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd" xmlns="http://maven.apache.org/SETTINGS/1.1.0"

        </properties>
    </profile>

  </profiles>
  <activeProfiles>
    <activeProfile>artifactory</activeProfile>
  </activeProfiles>
</settings>

现在我需要使用Maven jaxb2插件，

 <groupId>org.jvnet.jaxb2.maven2</groupId>
 <artifactId>maven-jaxb2-plugin</artifactId>
 <version>${maven-jaxb2-plugin.version}</version>

在我的本地存储库中不存在。

运行时会提示错误

Failure to find org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:jar:0.13.3 in http://10.2.2.29:8080/artifactory/mirrorOfmaven was cached in the local repository
