記錄一次發(fā)布jar包到maven中央倉庫的經(jīng)歷

1.注冊JIRA賬號

注冊地址：https://issues.sonatype.org/secure/Dashboard.jspa
注：這里密碼要設置規(guī)則有點麻煩俱两，看它的提示設置

2.創(chuàng)建 issue

image.png

參考已經(jīng)審核通過的

image.png

這些都是要填寫的卒茬！Project URL 和SCM url 可以填寫自己github項目的地址
創(chuàng)建好以后 sonatype的工作人員審核處理焕议，速度還是很快的，一般一個工作日以內(nèi)就有回復

比如：

image.png

讓你驗證下是否是你自己填寫的冻河，一般有幾種方式原环，常用選擇第一種

• Add a TXT record to your DNS referencing this JIRA ticket: OSSRH-54313 (Fastest)

自己添加好DNS后坝锰，再次點擊回應按鈕，一般還是一個工作日內(nèi)會回復你：

image.png

這個就代表好了今魔，可以繼續(xù)操作了

3.配置maven Setting.xml文件

image.png

id要和pom中的id對應勺像，配置過私服的應該都知道

image.png

用戶名密碼是注冊jira的用戶名密碼

4.windows環(huán)境安裝gpg4win

下載地址：https://www.gpg4win.org/download.html
安裝成功后障贸，進入cmd，輸入命令：
gpg --gen-key

中間提示你要設置名字+郵箱吟宦，其他可以使用默認值篮洁，記住輸入的passphrase，后面mvn deploy會用到

image.png

5.上傳密鑰

上傳剛剛生成的秘鑰
gpg --keyserver hkp://keyserver.ubuntu.com:11371 --send-keys 公鑰ID

image.png

常用gpg命令如下：

查看是否安裝成功
gpg --version

生成密鑰對
gpg --gen-key

查看公鑰
gpg --list-keys

將公鑰發(fā)布到PGP密鑰服務器
gpg --keyserver hkp://keyserver.ubuntu.com:11371 --send-keys 公鑰ID

查詢公鑰是否發(fā)布成功
gpg --keyserver hkp://keyserver.ubuntu.com:11371 --recv-keys 公鑰ID

下面是上傳好的效果圖

6.配置pom.xml（重點）

這里有好多坑殃姓，所以直接copy操作好的pom出來

嚴格來說這些<licenses> <scm><>plugin都要配置袁波，甚至name,description,url都要配置

如果不配置，deploy的時候會報錯

7.maven deploy

和操作私服一樣

image.png

build過程中會讓你輸入之前填寫的passphrase

image.png

最后看到BUILD SUCCESS，就代表成功了叫倍，如果有錯誤偷卧，按照上面列的3種，解決掉再點一次deploy即可

8.發(fā)布到中央倉庫

登陸https://oss.sonatype.org/#stagingRepositories
用戶名密碼和注冊的jira賬號一樣

image.png

jira那邊也回復了

image.png

不過我這邊是需要搜索下才顯示
https://search.maven.org

image.png

image.png

注：如果沒有通過配置自動發(fā)布插件nexus-staging-maven-plugin听诸，進行mvn deploy，是看不到的蚕泽，而且需要手動drop掉晌梨，比如：
