向maven中央仓库提交jar
从来都是从中央仓库下载jar,这次需要向中央仓库提交jar, 利用Sonatype OSSRH可以把jar等资源提交给Maven的中央仓库。
Sonatype OSSRH介绍：
Sonatype OSSRH使用Nexus 为开源项目提供仓库管理服务，该仓库就是所谓maven的中央仓库，OSSRH允许我们向Maven中央仓库提交二进制文件。
1:提交(deploy)开发版本的二进制文件（snapshorts)
2: 阶段性的发布版本
3：发布一个release,然后同步他们到中央仓库。
初始阶段
1：注册一个JIRA账号：https://issues.sonatype.org/secure/Signup!default.jspa
2：创建一个新工程的单：https://issues.sonatype.org/secure/CreateIssue.jspa?issuetype=21&pid=10134
只有当这个jira单的状态我resolved时，才可以提交jar包
审查要求
1：提供javadoc和source
2: 使用gpg或者pgp对文件进行签名
3: pom.xml文件
4：正确的坐标：groupId,artifactId,version
<groupId>com.sequoiadb</groupId> <artifactId>sequoiadb-driver</artifactId> <version>1.12</version>
5: projectName,description,url等。
<name>${project.groupId}:${project.artifactId}</name> <description>SequoiaDB Driver Library</description> <url>https://github.com/SequoiaDB/SequoiaDB</url>
6： license 信息
<licenses> <license> <name>The Apache License, Version 2.0</name> <url>http://www.apache.org/licenses/LICENSE-2.0.txt</url> </license> </licenses>
7 ： 开发者信息
<developers> <developer> <name>linyoubing</name> <email>linyoubing@sequoiadb.com</email> <organization>sequoiadb</organization> <organizationUrl>http://www.sequoiadb.com</organizationUrl> </developer> </developers>
8： SCM信息
<scm> <connection> scm:git:https://github.com/SequoiaDB/SequoiaDB.git </connection> <developerConnection> scm:git:https://github.com/SequoiaDB/SequoiaDB.git </developerConnection> <url>https://github.com/SequoiaDB/SequoiaDB</url> <tag>v1.12</tag> </scm>
部署
可以使用多种方式部署，这是使用maven的方式
1：分布管理和认证:
我使用了maven部署插件，所以pom.xml中加入：
<distributionManagement> <snapshotRepository> <id>ossrh</id> <url>https://oss.sonatype.org/content/repositories/snapshots</url> </snapshotRepository> <repository> <id>ossrh</id> <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url> </repository> </distributionManagement>
需要在maven_home/conf/settings.xml配置jira的账号和密码
<settings> <servers> <server> <id>ossrh</id> <username>your-jira-id</username> <password>your-jira-pwd</password> </server> </servers> </settings>
2：配置生成javadoc和sources包的插件：
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-source-plugin</artifactId> <version>2.2.1</version> <executions> <execution> <id>attach-sources</id> <goals> <goal>jar-no-fork</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>2.9.1</version> <executions> <execution> <id>attach-javadocs</id> <goals> <goal>jar</goal> </goals> </execution> </executions> </plugin>
3：GPG自动签名的插件：
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-gpg-plugin</artifactId> <version>1.5</version> <executions> <execution> <id>sign-artifacts</id> <phase>verify</phase> <goals> <goal>sign</goal> </goals> </execution> </executions> </plugin>
在settings.xml中配置gpg的签名 ：（需要先用gpg来生成）
<settings> <profiles> <profile> <id>ossrh</id> <activation> <activeByDefault>true</activeByDefault> </activation> <properties> <gpg.executable>gpg2</gpg.executable> <gpg.passphrase>the_pass_phrase</gpg.passphrase> </properties> </profile> </profiles> </settings>
4: 使用Profile
应该javadoc和source的jar包生成也需要使用gpg来签名，所以很浪费时间，而且这些执行通常都独立于标准构建流程，所以把他们移动到一个profile.
<profiles> <profile> <id>release</id> <build> <plugins> <plugin> <groupId>org.sonatype.plugins</groupId> <artifactId>nexus-staging-maven-plugin</artifactId> <version>1.6.3</version> <extensions>true</extensions> <configuration> <serverId>ossrh</serverId> <nexusUrl>https://oss.sonatype.org/</nexusUrl> <autoReleaseAfterClose>true</autoReleaseAfterClose> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-release-plugin</artifactId> <version>2.5</version> <configuration> <autoVersionSubmodules>true</autoVersionSubmodules> <useReleaseProfile>false</useReleaseProfile> <releaseProfiles>release</releaseProfiles> <goals>deploy</goals> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <version>3.0</version> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-gpg-plugin</artifactId> <version>1.5</version> <executions> <execution> <id>sign-artifacts</id> <phase>verify</phase> <goals> <goal>sign</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-source-plugin</artifactId> <version>2.2.1</version> <executions> <execution> <id>attach-sources</id> <goals> <goal>jar-no-fork</goal> </goals> </execution> </executions> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-javadoc-plugin</artifactId> <version>2.9</version> <executions> <execution> <id>attach-javadocs</id> <goals> <goal>jar</goal> </goals> </execution> </executions> </plugin> </plugins> </build> </profile> </profiles>
提交一个snapshot版本：
1：修改version加一个-SNAPSHOT, 执行 mvn clean deploy
发布一个release版本
1：修改version 不要加-SNAPSHOT, 可以手动修改，也可以执行
mvn versions:set -DnewVersion=1.2.3
2: 执行 mvn clean deploy -P release
