maven - maven 返回码是：409，ReasonPhrase：冲突

问题描述

我在部署具有以下结构的多模块 python 项目时遇到问题

parent pom.xml # common pom for others project
project/ 
   pom.xml # project pom
   common_features/
        sub-project-1/pom.xml # sub project 1 pom
        sub-project-2/pom.xml # sub project 2 pom

对于部署，我使用 Maven

设置.xml

用于构建的一般 Maven 设置

<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <!-- others options -->
  <servers>
    <server>
      <id>artifacts-SNAPSHOTS</id>
      <username>user</username>
      <password>password</password>
    </server>
   </servers>
  <!-- others options -->
</settings>

父 pom.xml

在这种情况下，我们有相同的 SNAPSHOT 和 RELEASE 存储库 URL

    <artifacts.repository.url>https://domain/artifactory/mvn-repo-dev</artifacts.repository.url>
</properties>

项目 pom.xml

在那里你可以看到该项目包含两个模块

父母是一般父母。我还起诉了 maven 程序集插件，以便将项目部署到工件中

工件描述.xml

我只想部署一些部分，因此我定义了以下部署文件。有了这个，我确保到包中将只部署通用功能和项目特定的脚本/代码

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.3"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-    plugin/assembly/1.1.3 http://maven.apache.org/xsd/assembly-1.1.3.xsd">

            </excludes>
        </fileSet>
    </fileSets>
</assembly>

子项目 1 pom.xml

这只是没有其他插件和构建选项的简单 pom

<parent>
    <groupId>com.project.group.id</groupId>
    <artifactId>project-pom</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../../pom.xml</relativePath>
</parent>

<packaging>pom</packaging>
<groupId>com.project.group.id</groupId>
<artifactId>sub-project-1</artifactId>
<version>1.0.0-SNAPSHOT</version>

<properties>
    <subProjectName>project-1</subProjectName>
</properties>

子项目 2 pom.xml

与 sub-project-1 相同的 pom.xml

<parent>
    <groupId>com.project.group.id</groupId>
    <artifactId>project-pom</artifactId>
    <version>1.0.0-SNAPSHOT</version>
    <relativePath>../../pom.xml</relativePath>
</parent>

<packaging>pom</packaging>
<groupId>com.project.group.id</groupId>
<artifactId>sub-project-2</artifactId>
<version>1.0.0-SNAPSHOT</version>

<properties>
    <subProjectName>project-2</subProjectName>
</properties>

现在我只想构建 sub-project-1 并将其上传到 artifactory 中，因此我将使用以下 maven 命令：

mvn -e -B -U -X clean deploy --projects :sub-project-1 -DskipIntegrationTests=false -DskipCoverageReport=false

但随后出现以下错误：

Caused by: org.apache.maven.wagon.TransferFailedException: Failed to transfer file: https://domain/artifactory/mvn-repo-dev/com/project/group/id/project/project-1/1.0.0-SNAPSHOT/sub-project-1-1.0.0-20190723.081454-1.pom. Return code is: 409, ReasonPhrase: Conflict.

现在我不确定出了什么问题，我花了很多时间调查这个问题，但什么也没找到。请问您有什么建议吗？非常感谢

解决方案

我发现问题出在哪里。在父 pom.xml 中有以下插件可以更改 artifactId。我不知道为什么会出现错误 409，但最后这是一个原因：

        <plugin>
            <groupId>org.codehaus.groovy.maven</groupId>
            <artifactId>gmaven-plugin</artifactId>
            <executions>
                <execution>
                    <phase>pre-clean</phase>
                    <goals>
                        <goal>execute</goal>
                    </goals>
                    <configuration>
                        <source>
                            project.getModel().setArtifactId(project.properties["someProperty"].replaceAll('_',
                            '-'))
                            project.getArtifact().setArtifactId(project.properties["someProperty"].replaceAll('_',
                            '-'))
                        </source>
                    </configuration>
                </execution>
            </executions>
        </plugin>
