maven 配置增加

                                    org.apache.maven.plugins                maven-compiler-plugin                3.7.0                                    1.8                    1.8                    UTF-8                                                        org.apache.maven.plugins                maven-surefire-plugin                                    true                                                        maven-source-plugin                                                            attach-sources                        verify                                                    jar-no-fork                                                                                                    org.apache.maven.plugins                maven-source-plugin                                                            attach-sources                                                    jar                                                                                                    org.apache.maven.plugins                maven-javadoc-plugin                                    com.facebook.thrift:com.facebook.thrift.*                                                                            attach-javadocs                        package                                                    jar                                                                            none                                                                                                    org.apache.maven.plugins                maven-gpg-plugin                1.1                                                            sign-artifacts                        verify                                                    sign                                                                                                        

运行maven 命令

mvn  -Dmaven.test.skip=true verify -Dgpg.passphrase="秘钥密码"

然后target 下会生成一下文件 mvn -Dmaven.test.skip=true verify -Dgpg.passphrase="秘钥密码"

mars-validated-1.0.3.pommars-validated-1.0.3.jarmars-validated-1.0.3.jar.asmars-validated-1.0.3.pom.ascmars-validated-1.0.3-javadoc.jarmars-validated-1.0.3-javadoc.jar.ascmars-validated-1.0.3-sources.jarmars-validated-1.0.3-sources.jar.asc

然后访问https://oss.sonatype.org/ 进行登录

左侧菜单选择 >Staging Upload

1、Upload Mode: 选择 Artifact(s) with a POM2、Select Pom to Upload 选择 mars-validated-1.0.3.pom上传3、Select Artifact(s) to Upload 选择以下7个文件一个一个的添加

mars-validated-1.0.3.jarmars-validated-1.0.3.jar.asmars-validated-1.0.3.pom.ascmars-validated-1.0.3-javadoc.jarmars-validated-1.0.3-javadoc.jar.ascmars-validated-1.0.3-sources.jarmars-validated-1.0.3-sources.jar.asc

4、 Upload Artifact(s) 上传

然后进入发布页面左侧 -》Staging Repositories

1、先刷新然后选择你上传的jar （比较慢多等会）直到出现 Release 按钮，才算是jar包发布成功。如果没有出现，则表示jar签名出现错误。最后选中jar Release 发布即可

发布成功后1~2天才能在中央仓库看到。1天后就可以下载到
