maven-3 - 无法从神器中找到神器

Question

我在 Maven 3.2.1 中使用 JFrog artifactory 3.2.1.1。

我上传了一个已构建的项目，该项目存在于存储库浏览器下的 libs-snapshot-local 中。如果我浏览到 com.foo.project，我将在 artifactory 浏览器中看到 project-1.0-20151113.133436-1.jar 文件和 pom 和元数据。

连访问http://example.com:8081/artifactory/webapp/browserepo.html?42&pathId=libs-snapshot-local:com/foo/project/1.0-SNAPSHOT/project-1.0-20151113.133436-1.jar向我展示了里面的 jar 文件。

我使用了 artifactory 中的 settings.xml 生成器来生成 <repository>我在以下 pom.xml 中使用的标记:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>

    </repository>
  </repositories>

    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-dependency-plugin</artifactId>
        <executions>
          <execution>
            <id>unpack</id>
            <phase>prepare-package</phase>
            <goals>
              <goal>unpack</goal>
            </goals>
            <configuration>
              <artifactItems>
                <artifactItem>
                  <groupId>com.foo</groupId>
                  <artifactId>project</artifactId>
                  <version>1.0</version>
                  <type>jar</type>
                  <includes>myFolder</includes>
                  <outputDirectory>${project.build.directory}/newFolder/js/gmoketest</outputDirectory>
                </artifactItem>
              </artifactItems>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

我只是得到:

Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:unpack (unpack) on project exampleApp: Unable to find artifact. Failure to find com.foo:project:jar:1.0 in http://example.com:8081/artifactory/libs-snapshot was cached in the local repository, resolution will not be reattempted until the update interval of snapshots has elapsed or updates are forced

如果我改变
http://example.foo:8081/artifactory/libs-snapshot

到
http://example.foo:8081/artifactory/libs-snapshot-local
然后我得到:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.8:unpack (unpack) on project exampleApp: Unable to resolve artifact. Could not transfer artifact com.foo:project:jar:1.0 from/to snapshots (http://example.com:8081/artifactory/libs-snapshot-local): Failed to transfer file: http://example.com:8081/artifactory/libs-snapshot-local/com/foo/project/1.0/project-1.0.jar. Return code is: 409 , ReasonPhrase:Conflict.

我会不时地将新快照部署到同一个 project-1.0，并希望这个 pom 文件在从 Artifactory 构建时只包含最新的 SNAPSHOT 构建。

Answer 1

答案是，我很快发现需要将版本指定为:

<version>1.0-SNAPSHOT</version>
