我正在使用 RavenDB 开发应用程序。我有针对嵌入式内存数据库的自动化测试。当我引用 Raven build 2033-Unstable 时，所有测试都运行良好。我升级到 build 2067-Unstable（现在是 2069），现在通过 TeamCity（7.1 build 23907）运行时，每个 NUnit 测试都出现异常。通过 R# 或 NUnit GUI 运行时，所有测试都运行良好。

我收到的例外似乎是NullReferenceExceptionRaven 的内部人员Raven.Bundles.Versioning.Triggers.VersioningPutTrigger.AllowPut(String key, RavenJObject document, RavenJObject metadata, TransactionInformation transactionInformation) in c:\Builds\RavenDB-Unstable-v1.2\Raven.Database\Bundles\Versioning\Triggers\VersioningPutTrigger.cs:line 22。我什至没有使用Versioning捆绑包。

这是完整的堆栈跟踪：

我正在使用 Autofac 将其连接起来，该代码如下所示：

    protected override void Load(ContainerBuilder builder)
    {
        builder.Register(c => new EmbeddableDocumentStore
                              {
                                  RunInMemory = true,
                                  Configuration =
                                      {
                                          PluginsDirectory = GetPluginsDirectory()
                                      }
                              })
            .OnActivating(a => RavenModule.Initialize(a.Instance))
            .As<IDocumentStore>()
            .Named<IDocumentStore>("test")
            .InstancePerLifetimeScope();
    }

    private static string GetPluginsDirectory()
    {
        return Path.GetDirectoryName(typeof (UniqueConstraintsPutTrigger).Assembly.Location);
    }

    public static void Initialize(DocumentStoreBase store)
    {
        store.RegisterListener(new UniqueConstraintsStoreListener());
        store.Initialize();
        IndexCreation.CreateIndexes(typeof (RavenModule).Assembly, store);
        RequireTrigger(store, typeof (UniqueConstraintsPutTrigger));
    }

    private static void RequireTrigger(IDocumentStore store, Type triggerType)
    {
        var installedTriggerNames = store.DatabaseCommands.GetStatistics().Triggers.Select(t => t.Name);

        if (!installedTriggerNames.Contains(triggerType.ToString()))
        {
            throw new Exception(string.Format(
                "The required trigger '{0}' was not detected. Verify the bundle '{1}' been installed into the" +
                " server's plugins directory.",
                triggerType, Path.GetFileName(triggerType.Assembly.Location)));
        }
    }

解决了。将 设置为PluginsDirectory与所有其他 DLL 相同的文件夹，尤其是Raven.Database.dll，会导致该 DLL 中嵌入的所有插件也被无意加载。并非所有的 Raven 插件都可以一起工作，因此加载它们都会导致异常。通过创建一个单独的Plugins目录并将其复制Raven.Bundles.UniqueConstraints.dll到该目录中，可以使异常停止发生。

我仍然不明白为什么它只是从构建服务器失败；似乎它也应该在本地失败。
