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

Return code is: 400

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

        <version>2.7</version>
        <executions>
          <execution>
            <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 文件中：

<settings>
  <server>
      <id>releases</id>
      <username>admin</username>
      <password>admin123</password>
    </server>
    <server>
      <id>snapshots</id>
      <username>admin</username>
      <password>admin123</password>
    </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个时候有效，但现在它吐出了一个错误。不知道出了什么问题。

并且 nexus 日志告诉我它正在尝试将快照上传到发布存储库

jvm 1    | 2012-06-04 14:16:31 INFO  [tp1706427008-35] - org.sonatype.nexus.proxy.maven.maven2.M2Repository - Storing of item releases:/info/afilias/edr/edr-app/1.0.4-SNAPSHOT/edr-app-1.0.4-20120604.181534-1.tar.gz is forbidden by Maven Repository policy. Because releases is a RELEASE repository

您的 settings.xml 不正确。请按照本书章节配置 Maven 以正确使用Nexus。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 deploy-file 目标左右。

只需运行命令

mvn clean deploy

在构建上。

另一个澄清。Maven 将部署根据版本确定的任何内容。如果它以 -SNASPHOT 结尾，则它是一个开发版本并被发布到快照存储库（并且将允许重新部署增加版本号），如果不是，它被认为是一个发布，并将部署到发布存储库。一个项目不能同时是快照和发布。这是一个或另一个。

不要混合发布和快照这两个概念！

在部署额外的工件方面，如果它们没有关联，或者如果它们正在查看构建助手插件的 attach-artifact 目标，我会将它们拉出到单独的项目/模块中。

这是因为您告诉 Maven 部署一个看起来像快照的文件。看看你的 deploy:deploy-file 配置。${revision} 具有与快照相同的格式，因此 Nexus 对其进行了处理：

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

作为参考，这里介绍了 Maven 和 Nexus 用来决定快照是/不是什么的正则表达式：http: //www.sonatype.com/people/2008/05/maven-code-how-to-detect-if-你有一个快照版本/

我建议的另一件事是不要使用 deploy:deploy-file，而是使用 buildhelper:attach 附加此 tar.gz，然后文件将被适当命名，避免您对修订所做的所有黑客攻击。
