理解Apache发布的内容和流程
总的来说，Source Release是Apache关注的重点，也是发布的必须内容；而Binary Release是可选项，Dubbo可以选择是否发布二进制包到Apache仓库或者发布到Maven中央仓库。

Maven Release Info
本地构建环境准备
主要包括签名工具、Maven仓库认证相关准备
安装GPG，参见 https://www.gnupg.org/download/index.html
如Mac OS
$ brew install gpg
$ gpg --version #检查版本，应该为2.x
用gpg生成key
根据提示，生成key
$ gpg2 --full-gen-key

Please select what kind of key you want:
(1) RSA and RSA (default)
(2) DSA and Elgamal
(3) DSA (sign only)
(4) RSA (sign only)
Your selection? 1
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048) 4096
Requested keysize is 4096 bits
Please specify how long the key should be valid.
0 = key does not expire
<n> = key expires in n days
<n>w = key expires in n weeks
<n>m = key expires in n months
<n>y = key expires in n years
Key is valid for? (0)
Key does not expire at all
Is this correct? (y/N) y
GnuPG needs to construct a user ID to identify your key.
Real name: Robert Burrell Donkin
Email address: [email protected]
Comment: CODE SIGNING KEY
You selected this USER-ID:
"Robert Burrell Donkin (CODE SIGNING KEY) <[email protected]>"
Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
You need a Passphrase to protect your secret key. # 填入密码，以后打包过程中会经常用到
查看key id
$ gpg --list-keys
pub rsa4096/28681CB1 2018-04-26 # 28681CB1就是key id
uid [ultimate] liujun (apache-dubbo) <[email protected]>
sub rsa4096/D3D6984B 2018-04-26
通过key id发送public key到keyserver
$ gpg --keyserver pgpkeys.mit.edu --send-key 28681CB1
如果有多个public key，设置默认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
设置Apache中央仓库
Dubbo项目的父pom为apache pom
<parent>
<groupId>org.apache</groupId>
<artifactId>apache</artifactId>
<version>19</version>

添加以下内容到.m2/settings.xml

打包&上传 从主干分支拉取新分支作为发布分支，如现在要发布2.6.4版本，则从2.6.x拉出新分支2.6.4-release，此后2.6.4 Release Candidates涉及的修改及打标签等都在2.6.4-release分支进行，最终发布完成后合入主干分支。 首先，在2.6.4-release分支验证maven组件打包、source源码打包、签名等是否都正常工作 $ mvn clean install -Papache-release $ mvn deploy # 将snapshot包推送到maven中央仓库，处于staging状态 用maven-release-plugin发布 先用dryRun验证是否ok $ mvn release:prepare -Papache-release -Darguments="-DskipTests" -DautoVersionSubmodules=true -Dusername=YOUR GITHUB ID -DdryRun=true 验证通过后，执行release:prepare $ mvn release:clean $ mvn release:prepare -Papache-release -Darguments="-DskipTests" -DautoVersionSubmodules=true -Dusername=YOUR GITHUB ID # 执行完成后：1.生成source.zip包； 2.打出tag，并推送到github仓库； 3.分支版本自动升级为2.6.4-SNAPSHOT，并将修改推送到github仓库 执行release:perform，做正式发布 $ mvn -Prelease release:perform -Darguments="-DskipTests" -DautoVersionSubmodules=true -Dusername=YOUR GITHUB ID # 所有artifacts发布到配置的远程maven中央仓库，处于staging状态 准备Apache发布 准备svn本机环境（Apache使用svn托管项目的发布内容） 将dubbo checkout到本地目录 $ svn checkout https://dist.apache.org/repos/dist/dev/incubator/dubbo # 假定本地目录为 ~/apache/incubator/dubbo 当前发布版本为2.6.4，新建目录 $ cd ~/apache/incubator/dubbo # dubbo svn根目录 $ mkdir 2.6.4 添加public key到KEYS文件。KEYS主要是让参与投票的人在本地导入，用来校验sign的正确性 拷贝Dubbo根目录下的source.zip包到svn本地仓库dubbo/2.6.4 生成sha512签名 $ 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要同时发布 # 到dubbo项目distribution的module下，执行： $ mvn install # target目录下，拷贝bin-release.zip以及bin-release.zip.asc到svn本地仓库dubbo/2.6.4 # 参考第6步，生成sha512签名 提交到Apache svn $ svn status $ svn commit -m 'prepare for 2.6.4 RC1' 验证Release Candidates 证环节包含但不限于以下内容和形式： 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. 进入投票 投票分两个阶段： Dubbo社区投票，发起投票邮件到
[email protected]。在社区开发者Review，并统计到3个同意发版的binding票后，即可进入下一阶段的投票。 Apache社区投票，发起投票邮件到
[email protected]。在Apache PMC Review，并统计到3个统一发版的binding票后，即可进行正式发布。 邮件模板： Hello Dubbo Community, This is a call for vote to release Apache Dubbo (Incubating) version 2.6.4. The release candidates: https://dist.apache.org/repos/dist/dev/incubator/dubbo/2.6.4/ Git tag for the release: https://github.com/apache/incubator-dubbo/tree/dubbo-2.6.4 Hash for the release tag: afab04c53edab38d52275d2a198ea1aff7a4f41e Release Notes: https://github.com/apache/incubator-dubbo/releases/tag/untagged-4775c0a22c60fca55118 The artifacts have been signed with Key : 28681CB1, which can be found in the keys file: https://dist.apache.org/repos/dist/dev/incubator/dubbo/KEYS The vote will be open for at least 72 hours or until necessary number of votes are reached. Please vote accordingly: [ ] +1 approve [ ] +0 no opinion [ ] -1 disapprove with the reason Thanks, The Apache Dubbo (Incubating) Team 正式发布 提交https://dist.apache.org/repos/dist/dev/incubator/dubbo目录下的发布包到https://dist.apache.org/repos/dist/release/incubator/dubbo/，完成正式发布。 发邮件到
[email protected]和
[email protected]，通知社区发布完成。 完成Maven Convenient Binary发布（可选） apache.repository.org nexus仓库的权限已经申请，参见jira。 之前发布到maven仓库的atifacts都处于staging状态，用Apache id登录apache.repository.org，完成发布。 [原文链接](http://click.aliyun.com/m/1000017271/) 本文为云栖社区原创内容，未经允许不得转载。
