Q:

plugin install through proxy

I am trying to install Graph-Aided Search to integrate Neo4j with ElasticSearch (2.3.1) as shown here. But when I try this command line:
plugin install com.graphaware.es/graph-aided-search/2.3.2.0

I get errors:
plugin install com.graphaware.es/graph-aided-search/2.3.2.0
-> Installing com.graphaware.es/graph-aided-search/2.3.2.0...

And this when I add --verbose for more details:

I looked for that error on google and I found that it might be because of the proxy, and since I am working behind a proxy I tried something that basically worked for others. This is the command line that I tried to install the plugin through proxy:
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

But still it didn't work, and I am still getting the same error. I forced the authentification to the proxy on Internet Explorer, something that usually works for me when I install packages with Maven. However, in that case it didn't work.
I am struggling to integrate my Neo4j database with ElasticSearch, I have been trying that for 4days now and it is taking all my time and cannot work without making this integration with success.
I really appreciate any help or clarification to resolve this error. Thank you.
[UPDATE]
When I try to replace the path, it is still not working. I've tried this command line: 
  plugin install C:\dev\graph-aided-search-master\target\releases\graph-aided‌​-search-2.4.1.4-SNAP‌​SHOT.zip

and I got this error message: 
 -> Installing C:\dev\graph-aided-search-master\target\releases\graph-aided‌​-search-2.4.1.4-SNAP‌​SHOT.zip... 
 ERROR: Invalid prefix or suffix

I put the graph-aided-search Zip file in the same folder as plugin file, so in C:\dev\elasticsearch-2.3.1\bin. Then I tried with the relative path, and I got this message:
> 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 ...

A:

You can download the plugin manually from the MavenRepository
https://mvnrepository.com/artifact/com.graphaware.es/graph-aided-search
