通过代理安装插件

Question

我正在尝试安装图形辅助搜索以将 Neo4j 与 ElasticSearch (2.3.1) 集成，如图 here 所示。但是当我尝试这个命令行时：

plugin install com.graphaware.es/graph-aided-search/2.3.2.0

我收到错误：

plugin install com.graphaware.es/graph-aided-search/2.3.2.0
-> Installing com.graphaware.es/graph-aided-search/2.3.2.0...

这是当我添加 --verbose 以获取更多详细信息时：

plugin install com.graphaware.es/graph-aided-search/2.3.2.0 --verbose
-> Installing com.graphaware.es/graph-aided-search/2.3.2.0...

我在 google 上查找了那个错误，我发现它可能是因为代理，并且因为我在代理后面工作，所以我尝试了一些基本上对其他人有用的东西。这是我尝试通过代理安装插件的命令行：

C:\dev\elasticsearch-2.3.1\bin> plugin -Dhttps.proxyHost=http://example.test.fr -Dhttps.proxyPort=3128 -Dhttps.proxyUser=SomeUser -Dhttps.proxyPassword=Password install com.graphaware.es/graph-aided-search/2.3.2.0

但还是不行，我仍然收到同样的错误。我在 Internet Explorer 上强制对代理进行身份验证，这在我使用 Maven 安装软件包时通常对我有用。但是，在那种情况下它不起作用。

我正在努力将我的 Neo4j 数据库与 ElasticSearch 集成，我已经尝试了 4 天了，它占用了我所有的时间，如果不成功集成就无法工作。

非常感谢您提供的任何帮助或说明来解决此错误。谢谢。

当我尝试替换路径时，它仍然不起作用。我试过这个命令行：

  plugin install C:\dev\graph-aided-search-master\target\releases\graph-aided‌-search-2.4.1.4-SNAP‌SHOT.zip

我收到了这条错误信息：

 -> Installing C:\dev\graph-aided-search-master\target\releases\graph-aided‌-search-2.4.1.4-SNAP‌SHOT.zip... 
 ERROR: Invalid prefix or suffix

我将图形辅助搜索 Zip 文件放在与插件文件相同的文件夹中，所以在 C:\dev\elasticsearch-2.3.1\bin 中。然后我尝试使用相对路径，我收到了这条消息：

> plugin install graph-aided-search-2.4.1.4-SNAPSHOT.zip --verbose
-> Installing graph-aided-search-2.4.1.4-SNAPSHOT.zip...
Trying https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/graph-aided-search-2.4.1.4-SNAPSHOT.zip/2.3.1/graph-aided-search-2.4.1.4-SNAPSHOT.zip-2.3.1.zip ...

您可以从 MavenRepository 手动下载插件

正确的语法是：
