Artifactory在启动时引发异常：“由于输入结束，无法映射任何内容”

标签： java windows maven artifactory

前几天，我下载并安装了JFrog Artifactory 6.10.0版的开源免费版本。使用Artifactory UI，我能够根据需要为Maven项目设置本地，远程和虚拟存储库，以便在工件上存储构建并将其用于获取Maven依赖项。具体来说，我是在初次打开UI时选择Maven进行设置的，它询问是否要设置存储库。

我正在Windows 10上将人工制品作为服务运行。如果很重要，我会说，当我第一次安装它时，当我从Eclipse运行maven“部署”目标时，我会收到401未经授权的错误。我使用的项目在pom.xml文件中具有适当的条目，并且在我的.m2文件夹中具有适当的settings.xml文件。即使我的settings.xml文件是使用管理员凭据创建的，也会发生401错误。我致力于在人工UI中更改权限，最终在为“ admin-access”用户提供所有权限后解决了该问题。需要明确的是，此时一切正常。当我从Eclipse运行“部署”目标时，就从代理存储库中下载了依赖项，并将工件存储在了工件中。

现在，当我启动Artifactory时，我看到了典型的启动动画，随后是一个显示以下内容的屏幕：

    {
  "errors" : [ {
    "status" : 500,
    "message" : "Artifactory failed to initialize: check Artifactory logs for errors."
  } ]
}

编辑：为澄清起见，我将添加一个显示上述JSON错误消息的屏幕，这是我进入http://localhost:8081/artifactory/webapp并等待启动动画结束时在屏幕上看到的唯一内容。该应用程序完全不可用，因为它仅显示上面的JSON并停留在显示它的屏幕上。那是我面临的中心问题。

在检查工件日志后，在系统信息转储部分之后，我看到以下内容：

在此方面的任何帮助将不胜感激。我不确定我是不是偶然发现了Artifactory错误，还是在创建回购协议，使用人工制品存储/获取依赖项时是否以某种方式破坏了应用程序？

如果有关系，这是我pom.xml文件的摘录（名称字段已更改，以避免任何可能的安全问题。）

    <distributionManagement>
    <repository>
        <id>central</id>
        <name>my_computer-releases</name>

    </snapshotRepository>

这是我的settings.xml文件（更改了加密的密码信息）

如果功能正常。我认为不必担心这个问题。它只是抱怨某些库的pom xml出于某种原因可能是空的。
