一行bash命令，用于将pom的Maven工件下载到指定的库

以下是我得到的信息：

mvn dependency:tree | grep ":compile" | sed 's/+//' | sed 's/-//' | sed 's/\\//' | sed 's/\|//g' | sed 's/ //g' | sed 's/:jar:/:/'| sed 's/:compile//' | sed 's/:/,/g' | sed 's/\[INFO\]//'

是的，这是初步的。我想这里有一个“cut”用法，可能是awk为

curl/wget构造一行http://central.maven.org/maven2/com/thoughtworks/xstream/xstream/1.4/xstream-1.4.jar

但我的Bash fu不在那里

显然，考虑到正在进行的所有管道，后续的curl/wget钻头是很容易的。这只是URL的结构，这是遥不可及的

这就是我所拥有的东西的结局（所以你不必理解Maven）：

因此，我无法按要求使用oneliner，但一个小的Python脚本很合适：

# pip3 install sh
from sh import mvn, grep, rm, mkdir, sed, wget
import csv

rm("-rf", "libs")
mkdir("libs")

tree = sed(sed(mvn("dependency:tree", _tty_out=False), "s/\\[INFO\\]//"), "/\\[WARNING\\]/d")
lines = sed(sed(sed(sed(sed(sed(sed(sed(tree, "s/+//"), "s/-//"), "s/\\\//"), "s/\|//g"), "s/ //g"), "s/:jar:/:/"), "s/:/,/g"), "s/\[INFO\]//")

for gav in csv.reader(lines):
    if (len(gav) is not 4):
        continue

    mkdir("-p", "libs/" + gav[3])
    try:
        wget("http://central.maven.org/maven2/" + gav[0].replace(".", "/") + "/" + gav[1] + "/" + gav[2] + "/" + gav[1] + "-" + gav[2] + ".jar", "-O", "libs/" + gav[3] + "/" + gav[1] + "-" + gav[2] + ".jar")
    except:
        pass

编辑：Maven Resolver还有一个Ant功能，我被告知：

如果您认为bash one liner仍然可行，请明确指定您的输入以及从下面工作的Python脚本的See输出中需要的确切输出，Inian:）

# pip3 install sh
from sh import mvn, grep, rm, mkdir, sed, wget
import csv

rm("-rf", "libs")
mkdir("libs")

tree = sed(sed(mvn("dependency:tree", _tty_out=False), "s/\\[INFO\\]//"), "/\\[WARNING\\]/d")
lines = sed(sed(sed(sed(sed(sed(sed(sed(tree, "s/+//"), "s/-//"), "s/\\\//"), "s/\|//g"), "s/ //g"), "s/:jar:/:/"), "s/:/,/g"), "s/\[INFO\]//")

for gav in csv.reader(lines):
    if (len(gav) is not 4):
        continue

    mkdir("-p", "libs/" + gav[3])
    try:
        wget("http://central.maven.org/maven2/" + gav[0].replace(".", "/") + "/" + gav[1] + "/" + gav[2] + "/" + gav[1] + "-" + gav[2] + ".jar", "-O", "libs/" + gav[3] + "/" + gav[1] + "-" + gav[2] + ".jar")
    except:
        pass
