"java -jar jruby-complete.jar -S gem install yard" creates uri:classloader: directory when GEM_HOME is not set

[mkristian]

java -jar maven/jruby-complete/target/jruby-complete-9.0.0.0.pre1.jar -S gem install yard
Fetching: yard-0.8.7.6.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    You don't have write permissions for the uri:classloader:/META-INF/jruby.home/lib/ruby/gems/shared directory.

but also

$ ls -1
uri:classloader:

this is already fixed

Hi! I'm still seeing this issue in the 9000 release:

C:\Users\abc\Desktop\jrubydemo>java -jar .\jruby-complete-9.0.0.0.jar --version
jruby 9.0.0.0 (2.2.2) 2015-07-21 e10ec96 Java HotSpot(TM) 64-Bit Server VM 25.51-b03 on 1.8.0_51-b16 +jit [Windows 8.1-amd64]

well, not sure it says there is no write permissions into the classloader. the problem is that default GEM_HOME is inside the jruby-complete.jar so bundler can NOT install gems there.

if the whole thing does create some strange file like "uri:classloader:/" in your current directory then this bug is not fixed.

but to use bundler or even the gem command with jruby-complete.jar you need to set GEM_HOME to install gems.
