總的來說,Source Release是Apache關注的重點,也是發布的必須內容;而Binary Release是可選項,Dubbo可以選擇是否發布二進制包到Apache倉庫或者發布到Maven中央倉庫。
請參考以下鏈接,找到更多關于ASF的發布指南:
Apache Release Guide
Apache Release Policy
Maven Release Info
主要包括簽名工具、Maven倉庫認證相關準備
安裝GPG,參見 https://www.gnupg.org/download/index.html
如Mac OS
$ brew install gpg $ gpg --version #檢查版本,應該為2.x
用gpg生成key

查看key id
$ gpg --list-keys pub rsa4096/28681CB1 2018-04-26 # 28681CB1就是key iduid [ultimate] liujun (apache-dubbo) <liujun@apache.org> sub rsa4096/D3D6984B 2018-04-26# 通過key id發送public key到keyserver$ gpg --keyserver pgpkeys.mit.edu --send-key 28681CB1# 其中,pgpkeys.mit.edu為隨意挑選的keyserver,keyserver列表為:https://sks-keyservers.net/status/,因為相互之間是自動同步的,選任意一個都可以。
如果有多個public key,設置默認key
~/.gnupg/gpg.conf
# If you have more than 1 secret key in your keyring, you may want to# uncomment the following option and set your preferred keyid.default-key 28681CB1
根據提示,生成key
設置Apache中央倉庫
<settings>... <servers> <!-- To publish a snapshot of some part of Maven --> <server> <id>apache.snapshots.https</id> <username> <!-- YOUR APACHE LDAP USERNAME --> </username> <password> <!-- YOUR APACHE LDAP PASSWORD (encrypted) --> </password> </server> <!-- To stage a release of some part of Maven --> <server> <id>apache.releases.https</id> <username> <!-- YOUR APACHE LDAP USERNAME --> </username> <password> <!-- YOUR APACHE LDAP PASSWORD (encrypted) --> </password> </server> ... <!-- gpg passphrase used when generate key --> <server> <id>gpg.passphrase</id> <passphrase><!-- yourKeyPassword --></passphrase> </server> </servers></settings>
Dubbo項目的父pom為apache pom
<parent> <groupId>org.apache</groupId> <artifactId>apache</artifactId> <version>19</version></parent>
添加以下內容到.m2/settings.xml
所有密碼請使用[maven-encryption-plugin](http://maven.apache.org/guides/mini/guide-encryption.html)加密后再填入
從主干分支拉取新分支作為發布分支,如現在要發布2.6.4版本,則從2.6.x拉出新分支2.6.4-release,此后2.6.4 Release Candidates涉及的修改及打標簽等都在2.6.4-release分支進行,最終發布完成后合入主干分支。
首先,在2.6.4-release分支驗證maven組件打包、source源碼打包、簽名等是否都正常工作
$ mvn clean install -Papache-release $ mvn deploy# 將snapshot包推送到maven中央倉庫,處于staging狀態
用maven-release-plugin發布
$ mvn release:clean $ mvn release:prepare -Papache-release -Darguments="-DskipTests" -DautoVersionSubmodules=true -Dusername=YOUR GITHUB ID# 執行完成后:1.生成source.zip包; 2.打出tag,并推送到github倉庫; 3.分支版本自動升級為2.6.4-SNAPSHOT,并將修改推送到github倉庫
執行release:perform,做正式發布
$ mvn -Prelease release:perform -Darguments="-DskipTests" -DautoVersionSubmodules=true -Dusername=YOUR GITHUB ID# 所有artifacts發布到配置的遠程maven中央倉庫,處于staging狀態
先用dryRun驗證是否ok
$ mvn release:prepare -Papache-release -Darguments="-DskipTests" -DautoVersionSubmodules=true -Dusername=YOUR GITHUB ID -DdryRun=true
驗證通過后,執行release:prepare
準備svn本機環境(Apache使用svn托管項目的發布內容)
將dubbo checkout到本地目錄
$ svn checkout https://dist.apache.org/repos/dist/dev/incubator/dubbo# 假定本地目錄為 ~/apache/incubator/dubbo
當前發布版本為2.6.4,新建目錄
$ cd ~/apache/incubator/dubbo # dubbo svn根目錄$ mkdir 2.6.4
添加public key到 KEYS 文件。KEYS主要是讓參與投票的人在本地導入,用來校驗sign的正確性
拷貝Dubbo根目錄下的source.zip包到svn本地倉庫dubbo/2.6.4
生成sha512簽名
$ shasum -a 512 dubbo-incubating-2.6.4-source-release.zip >> dubbo-incubating-2.6.4-source-release.zip.sha512
如果有binary release要同時發布
# 到dubbo項目distribution的module下,執行:$ mvn install# target目錄下,拷貝bin-release.zip以及bin-release.zip.asc到svn本地倉庫dubbo/2.6.4# 參考第6步,生成sha512簽名
提交到Apache svn
$ svn status $ svn commit -m 'prepare for 2.6.4 RC1'
證環節包含但不限于以下內容和形式:
Check signatures and hashes are good
sha512 dubbo-incubating-${release_version}-bin-release.zip.sha512 sha512 dubbo-incubating-${release_version}-source-release.zip.sha512
unzip dubbo-incubating-${release_version}-source-release.zip to the default directory and check the following:
Directory with
incubator
in name
dubbo-incubating-${release_version}-bin-release
DISCLAIMER file exists
LICENSE and NOTICE file exists and contents are good
All files and no binary files exist
All files has standard ASF License header
Can compile from source
All unit tests can pass
mvn clean test # This will run all unit tests# you can also open rat and style plugin to check if every file meets requirements.mvn clean install -Drat.skip=false -Dcheckstyle.skip=false
Release candidates match with corresponding tags, you can find tag link and hash in vote email.
投票分兩個階段:
Dubbo社區投票,發起投票郵件到dev@dubbo.apache.org。在社區開發者Review,并統計到3個同意發版的binding票后,即可進入下一階段的投票。
Apache社區投票,發起投票郵件到general@apache.org。在Apache PMC Review,并統計到3個統一發版的binding票后,即可進行正式發布。
