Question

我正在尝试使用以下命令在maven中生成依赖树

$ mvn dependency:tree -DoutputType=dot

输出如下所示

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

[INFO]  } 
[INFO] ------------------------------------------------------------------------

它既具有直接依赖关系，又具有传递依赖关系，我希望它只是直接依赖关系，可以利用grep或某些标志-Dexcludes来帮助实现低于输出的效果

我期望像节点生态系统中的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。

请注意：我无法使用dependency:list，因为我需要上面的结构。

maven-dependency-plugin:list插件目标通过excludeTransitive选项提供了这种功能。但是，由于要查找 dot 图形输出格式，因此无法使用它。

该选项将以编程方式解析maven-dependency-plugin:tree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。

可以执行以下基本操作：

mvn org.apache.maven.plugins:maven-dependency-plugin:2.8:tree -DoutputType=dot -DoutputFile=out_temp & grep "com.a:test:jar:1.0" out_temp > out_final.gv & echo } >> out_final.gv & rm out_temp

以所需格式列出Maven项目的依赖项
