源服務(wù)器:
系統(tǒng): win
nexus版本: nexus-3.70.1-02-java8-win64

目標(biāo)服務(wù)器:
系統(tǒng): linux
nexus版本: 最新版
jdk: 17

這里有坑,
1, nexus-3.70.x最高支持jdk11 ,但是我們的環(huán)境是jdk17, 所以運(yùn)行不了,
2, 另外nexus-3.70.x之前是OrientDB, 之后是h2

剛開始各種辦法都試過(guò)了, 什么覆蓋,什么cli工具, 反正沒(méi)一個(gè)成功的, 后來(lái)采用同bat腳本直接遍歷上傳, 將bat放在私庫(kù)目錄, 然后運(yùn)行就可以
