Question

我想知道：有没有办法使用Maven Dependency plug-in（或其他在命令行上），从存储库列出工件的传递依赖关系（即pom.xml中的不）？

我知道可以使用mvn dependency:tree列出我本地项目的依赖项，但我想知道之前的某些内容的依赖关系我将它添加到我的项目中（即做出明智的决定），并将依赖项添加到本地pom.xml，唯一的目的是依赖插件似乎是hackish。

我希望我可以运行类似的东西：

mvn dependency:tree "-DgroupId=net.jawr" "-DartifactId=jawr-core" "-Dversion=3.5"

我提出的最好的是：

删除我的本地存储库（即~/.m2/repository）
运行mvn dependency:get "-DgroupId=net.jawr" "-DartifactId=jawr-core" "-Dversion=3.5"
检查输出

但这似乎非常 hackish and wasteful。

PS - 我不在乎它是否是树形格式。

我不知道有任何本机方式使用Maven，但是，我想出了以下shell脚本，它似乎可以完成这项工作：

#!/bin/sh
if [ "$#" -ne 3 ]; then
  echo "Usage: $0 <groupId> <artifactId> <version>"
  exit
fi

POM_DIR="`echo "$1" | tr . /`/$2/$3"
POM_PATH="$POM_DIR/$2-$3.pom"

mkdir -p "$HOME/.m2/repository/$POM_DIR"
wget -q -O "$HOME/.m2/repository/$POM_PATH" "http://repo.maven.apache.org/maven2/$POM_PATH"
mvn -f "$HOME/.m2/repository/$POM_PATH" dependency:tree

此脚本从Maven Central Repository下载您指定的工件的POM，然后为该POM运行dependency:tree目标。例如：

izstas@izstas-PC:~$ ./deptree net.jawr jawr-core 3.5

（如果我愿意，我可能会剥离不必要的Maven输出）

然而，这似乎下载.jar文件的依赖项，所以我不能说它是一个干净的解决方案。但至少它不需要您清除本地存储库。

如何从存储库列出工件的传递依赖性？
