1. 準備

注意：group id需要證明自己擁有這個域名，通過傳送郵件的方式。

第二天，通過人工稽核之後，status的狀態就變成了 RESOLVED，至此，我們完成了釋出前的準備工作。

2. 配置maven pom file

1.主要配置以下幾個地方：

  <modelVersion> 
  <groupId>
  <artifactId>
  <version>
  <packaging>
  <name>
  <description>
  <url
 
>
  <licenses>
  <scm><url>
  <scm><connection>
  <developers>

2.確保 <version> 標籤不包含 SNAPSHOT
3.add some info to pom file

<licenses>
        <license>
            <name>Apache License, Version 2.0</name>
            <url>http://www.apache.org/licenses/LICENSE-2.0.txt</url

            <distribution>repo</distribution>
        </license>
    </licenses>

        <url>[email protected]:Bytom/bytom-java-sdk.git</url>
    </scm>

4.add some plugins to pom file

<profiles>
        <profile>
            <id>release</id>
            <build>
                <plugins>
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-source-plugin</artifactId>
                        <version>2.2.1</version>

                            <execution>
                                <id>attach-sources</id>

                    </plugin>
                    <plugin>

                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                    <plugin>

                                <phase>verify</phase>
                                <goals>
                                    <goal>sign</goal>
                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                    <plugin>
                        <artifactId>maven-assembly-plugin</artifactId>
                        <version>2.3</version>
                        <configuration>
                            <descriptorRefs>
                                <descriptorRef>jar-with-dependencies</descriptorRef>
                            </descriptorRefs>
                        </configuration>
                        <executions>
                            <execution>
                                <phase>package</phase>
                                <goals>

                                </goals>
                            </execution>
                        </executions>
                    </plugin>
                </plugins>
            </build>
        </profile>
    </profiles>

    <distributionManagement>
        <snapshotRepository>
            <id>oss</id>
            <url>https://oss.sonatype.org/content/repositories/snapshots</url>
        </snapshotRepository>
        <repository>
            <id>oss</id>
            <url>https://oss.sonatype.org/service/local/staging/deploy/maven2/</url>
        </repository>
    </distributionManagement>

maven-assembly-plugin 外掛確保打包之後的 jar 包含了其所依賴的包。

5.add some info to setting.xml of maven

<servers>
    ...
    ...
    <server>
        <id>oss</id>
        <username>your username</username>
        <password>your password</password>
    </server>
</servers>

<profiles>
    <profile>
         <id>oss</id>
         <activation>
             <activeByDefault>true</activeByDefault>
         </activation>
         <properties>
             <gpg.executable>gpg</gpg.executable>
             <gpg.passphrase>your gpg password</gpg.passphrase>
         </properties>
    </profile>
</profiles>

3. 簽名

You can sign your project jars using pgp signatures.

4. 釋出

mvn clean deploy -Dmaven.test.skip=true -P release

通過這個命令，可以跳過測試，生成 jar，並呼叫 release profile 中的流程，通過GPG簽名，上傳到 Nexus Repositories 。

5. 等待

釋出成功之後就會在 maven central 和 maven repository 中搜索到相應的 pom 引用了。

6. 再發布

再發布的流程會簡化很多，只需要通過 maven 命令 deploy 之後，等待兩小時，就會同步到maven central。
