Using a `file://` prefix should work for *.gem file

[ph]

When trying to install a local *.gem it will fail if we use a file:// prefix.

MacBook-Pro-4:logstash-5.2.2 sarwar$ bin/logstash-plugin install file:///Users/sarwar/Downloads/logstash-filter-dissect-1.0.8.gem
ERROR: Invalid pack for: file:///Users/sarwar/Downloads/logstash-filter-dissect-1.0.8.gem, reason: Invalid format, the pack must be in zip format, message: Invalid format, the pack must be in zip form

Do any workarounds exist for this problem? (I've tried both file:// and file:/// schemes to no avail)

@andsel I noticed you are actively merging to the codebase so thought to bring this to your attention. I am facing the same issue where logstash is ignoring file path to my locally built filter gem file: Note: System: Windows 10 64 bit Logstash: v7.14.0-windows-x86_64

@samhaque you file is local so you need to pass --local to the bin\logstash-plugin install, try:

 bin\logstash-plugin.bat install --local C:/Users/samiul/Documents/logstash-7.14.0-windows-x86_64/logstash-7.14.0/logstash-filter-test-1.2.5.gem

@andsel Hello! I've tried to add key --local as you said, but unfortunately have no success, the error still the same. I am using logstash 8.10.4

[andsel]

Hi @hollden please could you provide more details:

• which plugin are you installing (or let us know where we can grab it) ?
• which command line did you issue?
• full listing of the error
