以所需格式列出Maven项目的依赖项 [英] List dependencies of maven project in desired format

问题描述

我正在尝试使用以下命令在maven中生成依赖树

Am trying to generate dependency tree in maven, making use of below command

$ mvn dependency:tree -DoutputType=dot

输出如下所示

[INFO] Scanning for projects...
[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水平

It has both direct and transitive dependencies, what i am expecting is just direct one , can making use of grep or some flags -Dexcludes helps to achieve below output

我期望节点生态系统中的像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.

Am expecting something like npm ls --depth=0 as in node ecosystem, were depth flags helps to just get direct dependencies.

注意:我无法使用dependency:list，因为我需要上面的结构.

Note: i can't make use of dependency:list as i need above structure.

推荐答案

maven-dependency-plugin:list插件目标通过

The maven-dependency-plugin:list plugin goal provides such a capability with the excludeTransitive option. But since you are looking for a dot graph output format, you cannot make use of it.

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，即不是以模块工件名称开头的行.

The option would be to programatically parse the output of the maven-dependency-plugin:tree output and delete transitive dependencies, i.e. the lines not starting with your module artifact name.

可以执行以下基本操作:

Something basic as the following would work:

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
