Maven 部署因冲突而失败

Question

我已经尝试了以下 maven 命令，

 - mvn clean install
 - mvn clean package
 - mvn clean deploy

前两个成功了，但是，最后一个（部署）失败并出现以下错误消息。对此的任何建议都会有所帮助

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project blkmessenger-parent: Failed to deploy artifacts: Could not transfer artifact com.jd.terf:blkmessenger-parent:pom:1.10.0-RC1-20190627.131740-1 from/to blkmessenger.snapshots (http://jd.artifactory.net:8081/artifactory/blkmessenger/snapshots): Failed to transfer file: http://jd.artifactory.net:8081/artifactory/blkmessenger/snapshots/com/jd/terf/blkmessenger-parent/1.10.0-RC1-SNAPSHOT/blkmessenger-parent-1.10.0-RC1-20190627.131740-1.pom.

Answer 1

Artifactory 在部署时返回 409 错误的原因有两个：

1. 将快照版本部署到不允许快照的存储库 - 处理快照设置为 false
2. 将 Release 版本部署到不允许发布的存储库 - Handle Releases 设置为 false
3. Checksum policy 设置为“根据客户端校验和验证”并且客户端已发送校验和，但它与服务器上计算的校验和相冲突，然后是 Artifactory
4. Suppress POM Consistency 设置为 true 且 POM 内的 groupId:artifactId:version 信息与部署路径不匹配
5. user plugin 可能会因为某些原因决定返回 409 错误

Answer 2

确保您的工件存储库允许快照。

进一步检查你的 groupId、artifact 和 version 的格式是否正确（版本以“-SNAPSHOT”结尾）。
