我正在尝试使用maven-deploy-plugin将版本和快照上传到Nexus存储库。但是我遇到了这个错误

这是我在pom.xml中的配置：

<project>
 ...
    <distributionManagement>
       <repository>
          <id>releases</id>
          <name>Releases</name>
          <url>http://localhost:8081/nexus/content/repositories/releases</url>
        </repository>
        <snapshotRepository>

          <name>Snapshots</name>
          <url>http://localhost:8081/nexus/content/repositories/snapshots</url>
        </snapshotRepository>
      </distributionManagement>

        <executions>

            <phase>deploy</phase>
            <goals>
              <goal>deploy-file</goal>
            </goals>
            <configuration>
              <file>target/edr-install-1.0.4-${revision}.tar.gz</file>
              <url>${project.distributionManagement.repository.url}</url>
              <packaging>tar.gz</packaging>
              <artifactId>artifactId</artifactId>
              <groupId>groupId</groupId>
              <version>1.0.4-${revision}</version>
            </configuration>
          </execution>
        </executions>
      </plugin>
   ...
  </build>
...
</project>

从我的settings.xml文件：

<settings>
  <server>
      <id>releases</id>
      <username>admin</username>
      <password>admin123</password>
    </server>

    </server>
  </servers>
  <profiles>
    <profile>
      <id>nexus</id>
      <activation>
        <activeByDefault>true</activeByDefault>
      </activation>
      <repositories>
        <repository>
          <id>releases</id>
          <name>Releases</name>
          <url>http://localhost:8081/nexus/content/repositories/releases</url>
          <releases>
            <enabled>true</enabled>
          </releases>
          <snapshots>
            <enabled>false</enabled>
          </snapshots>
        </repository>
        <repository>
          <id>snapshots</id>
          <name>Snapshots</name>
          <url>http://localhost:8081/nexus/content/repositories/snapshots</url>
          <releases>
            <enabled>false</enabled>
          </releases>
          <snapshots>
            <enabled>true</enabled>
          </snapshots>
        </repository>
      </repositories>
      </profile>
  </profiles>
</settings>

我确信这个配置在某一点上有效，但现在它正在吐出一个错误。不确定是什么问题。

nexus日志告诉我它正在尝试将快照上传到发布存储库

2 个答案:

答案 0 :(得分：3)

您的settings.xml不正确。请配置Maven以使用Nexus correctly following the book chapter.具体使用镜像设置和其中的URL，而不是存储库和pluginRepository的特定URL。

它会干扰您正确的Maven pom并最终尝试将快照部署到发布存储库中，这是不正确的。

此外，使用正确的目标/命令也很重要。不要直接使用部署文件目标。

只需运行命令

mvn clean deploy

在构建上。

另一个澄清。 Maven将部署从版本中确定的任何内容。如果它以-SNASPHOT结尾，则是一个开发版本并发布到快照仓库（并允许重新部署增加版本号），如果不是，则将其视为版本并将部署到版本仓库。项目不能同时是快照和发布。它是一个或另一个。

不要混合发布和快照这两个概念！

在获得部署其他工件方面，如果它们没有关联，或者它们正在查看构建帮助程序插件的attach-artifact目标，我会将它们拉出到一个单独的项目/模块中。

这是因为你告诉Maven部署一个看起来像快照的文件。看一下deploy：deploy-file config。 $ {revision}具有与快照相同的格式，因此Nexus无法解决它：

target / edr-install-1.0.4 - $ {revision} .tar.gz成为：info / afilias / edr / edr-app / 1.0.4-SNAPSHOT / edr-app-1.0.4-20120605.140242-20名为.tar.gz

参考Maven和Nexus用来决定快照是什么/不是什么的正则表达式在这里介绍： http://www.sonatype.com/people/2008/05/maven-code-how-to-detect-if-you-have-a-snapshot-version/

我建议的另一件事是不要使用deploy：deploy-file，而是使用buildhelper：attach来附加这个tar.gz然后文件将被恰当地命名，避免你用你做的所有黑客攻击修改
