Nexus Maven仓库迁移

Nexus Maven库迁移是开发环境迁移的重要一环，很多教程通过直接复制Nexus目录方式实现，但容器化部署Nexus时这种方式比较复杂，尤其是在公司容器平台部署的Nexus无法获取底层权限。

搜集到网上有通过shell脚本方式将Maven仓库文件一个个传到Nexus里仓库的方案，简单记录如下：

1.将所有要上传的镜像文件夹放到一个文件夹中，如/proxy

2.在文件夹内创建批量上传nexus库脚本mavenimport.sh

#!/bin/bash

# copy and run this script to the root of the repository directory containing files

# this script attempts to exclude uploading itself explicitly so the script name is important

# Get command line params

while getopts ":r:u:p:" opt; do

    case $opt in

        r) REPO_URL="$OPTARG"

        ;;

        u) USERNAME="$OPTARG"

        ;;

        p) PASSWORD="$OPTARG"

        ;;

    esac

done

  

find . -type f -not -path './mavenimport\.sh*' -not -path '*/\.*' -not -path '*/\^archetype\-catalog\.xml*' -not -path '*/\^maven\-metadata\-local*\.xml' -not -path '*/\^maven\-metadata\-deployment*\.xml' | sed "s|^\./||" | xargs -I '{}' curl -u "$USERNAME:$PASSWORD" -X PUT -v -T {} ${REPO_URL}/{} ;

3.赋予执行权限

chmod +x mavenimport.sh

4.执行，-u 用户名 -p 密码 -r 仓库地址

./mavenimport.sh -u admin -p 123 -r http://192.168.60.133:8081/repository/my_repo/

 

拓展：从Nexus某个仓库拉取所有依赖包到本地，并创建存放目录

#!/bin/bash

# 按需修改nexusurl和repository，修改要创建并存放依赖的本地目录名称
nexusurl=http://ip:port
repository=repository_name
continuationToken=""
dir=proxy

mkdir $dir
cd $dir
fetchComponents() {
    local token="$1"

    # 构建CURL命令
    local curlCmd="curl -s -X GET \"$nexusurl/service/rest/v1/components?repository=$repository"
    if [[ "$token" != "" ]]; then
        curlCmd="$curlCmd&continuationToken=$token"
    fi
    curlCmd="$curlCmd\" -H 'accept: application/json' -H 'NX-ANTI-CSRF-TOKEN: 0.028119600179752124' -H 'X-Nexus-UI: true'"

    # 执行请求
    local response=$(eval "$curlCmd")

    # 提取新continuationToken和组件信息
    local newContinuationToken=$(echo "$response" | jq -r '.continuationToken // empty')
    local components=$(echo "$response" | jq -r '.items[] | {group, name, version, path: .assets[].path}')

    # 输出组件信息并保存到文件（可按需调整输出方式）
    echo "$components" >> components_info.json

    # 如果有新的continuationToken，则递归调用
    if [[ "$newContinuationToken" != "" ]]; then
        echo "Fetching next page with continuationToken: $newContinuationToken"
        fetchComponents "$newContinuationToken"
    else
        echo "All components fetched."
    fi
}

# 初始化调用
fetchComponents "$continuationToken"

echo "All component data has been collected. Check components_info.json for details."

cat components_info.json | grep path | awk -F ':' '{print $2}' | cut -d "\"" -f 2 | sort | uniq > path1.txt
cat path1.txt | awk -F'/[^/]*$' '{print $1}' | sort | uniq > path2.txt


while IFS= read -r DIRNAME; do
    echo $DIRNAME
    if [ ! -d $DIRNAME ]; then
      mkdir -p $dir$DIRNAME
    fi
done < path2.txt

while IFS= read -r DIRNAME; do
    echo $DIRNAME
    DOWNLOAD_URL="$nexusurl/repository/$repository/$DIRNAME"
    if [ ! -f $DIRNAME ]; then
      wget $DOWNLOAD_URL -O $dir$DIRNAME
    fi
done < path1.txt

rm components_info.json
rm path2.txt
rm path1.txt
