我试图将依赖项添加到一个模块。这是代码:
<dependency>
<groupId>com.messagedna.dlp</groupId>
<artifactId>producer</artifactId>
<version>1.0</version>
</dependency>
以下是模块producer
的pom文件的一部分:
<parent>
<artifactId>DLP</artifactId>
<groupId>com.messagedna.dlp</groupId>
<version>1.0</version>
</parent>
<groupId>com.messagedna.dlp</groupId>
<artifactId>producer</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
<name>producer</name>
但是当我尝试编译第一个模块时,我得到以下内容:
