以所需格式列出maven项目的依赖关系

Question

我试图在maven中生成依赖树，利用下面的命令

$ mvn dependency:tree -DoutputType=dot

输出如下所示

[INFO] Scanning for projects...
[INFO]                                                                         
[INFO] ------------------------------------------------------------------------

[INFO]  "com.a:test:jar:1.0" -> "info.picocli:picocli:jar:2.3.0:compile" ;

[INFO]  } 
[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS
[INFO] ------------------------------------------------------------------------

它有直接和传递依赖，我期待的只是直接的，可以利用grep或一些标志-Dexcludes有助于实现以下输出

[INFO] Scanning for projects...
[INFO]

我希望在节点生态系统中像npm ls --depth=0这样的东西，深度标志有助于获得直接的依赖关系。

注意：我不能使用dependency:list，因为我需要上面的结构。

maven-dependency-plugin:list插件目标使用excludeTransitive选项提供了这样的功能。但是，由于您正在寻找点图输出格式，因此无法使用它。

选项是以编程方式解析qazxsw poi输出的输出并删除传递依赖项，即不以模块工件名称开头的行。

以下基本功能：

maven-dependency-plugin:tree
