maven，通过命令行客户端浏览中央存储库

Question

是否可以通过常规 mvn 命令行客户端浏览中央存储库，并可能执行特定搜索？

例如：我想获取其工件 ID 中包含“log4j”的所有工件的列表。

Answer 1

我编写了一个 Groovy 小脚本来执行此操作：

import groovyx.net.http.URIBuilder
import groovy.json.JsonSlurper

class Fun {
    public static void main(String[] args) {
        def uri = new URIBuilder("http://search.maven.org/solrsearch/select")
        uri.addQueryParam 'rows', 20
        uri.addQueryParam 'wt', 'json'
        uri.addQueryParam 'q', args[0]

        def text = uri.toURL().getText()

        def json = new JsonSlurper()

        def result = json.parseText( text )

        result.response.docs.each { doc ->
            println "$doc.id:$doc.latestVersion"
        }
    }
}

这是一个 Ruby 脚本，它可以做同样的事情（使用

httparty

gem）：

require 'httparty'

query = ARGV[0]

class MavenCentral
    include HTTParty
    base_uri 'search.maven.org'

    def initialize(query, rows=20)
        @options = { query: {rows: rows, wt: 'json', q: query} }
    end 

    def artifacts
       self.class.get('/solrsearch/select', @options)
    end 
end

maven_central = MavenCentral.new(query)
maven_central.artifacts['response']['docs'].each do |doc|
    puts "#{doc['id']}:#{doc['latestVersion']}"
end

有一个 SBT 插件：sbt-search-maven-plugin

Answer 3

mvn -q com.jarcasting:search-maven-plugin:search -Dq="com google guava"

搜索-maven-插件

Answer 4

询问“mvn命令行客户端”。没有任何脚本！仅 mvn 命令行客户端。
