Asset precompile works on development but fails on staging/production

[mmustala]

Im using JRuby and got tired of slow asset precompiling with the :uglifier and :sass compilers. I installed yui-compiler (0.12.0) and tried precompiling in development mode and it ran pretty fast. Everything was ok. Then when I deployed into our staging server with capistrano it threw an error.

I have JAVA_HOME set in the capistrano deploy.rb and also in the .profile file.

set :default_environment, {
    'JAVA_HOME' => '$HOME/java'
}

What could cause that in development environment the same file is successfully compressed but in other environment is not?

I'd go straight to the command that returned non-zero exit status and troubleshoot that. Log into the troublesome machine as the same user that you use to run this deploy script and run:

java -jar /home/staging/shared/bundle/jruby/1.9/gems/yui-compressor-0.12.0/lib/yui/../yuicompressor-2.4.8.jar --type js --charset utf-8 --nomunge /tmp/yui_compress20141218-31554-1h3vduh

My guess is you'll find that java doesn't exist on the path.

I have the same error on my production server when deploy with capistrano. When I run the command as @stevecrozz suggestion. It show error:

java.io.FileNotFoundException: /tmp/yui_compress20150521-2184-1p6a0d3 (No such file or directory)

I am sure my java is not missing.

$java -version
java version "1.7.0_79"
OpenJDK Runtime Environment (IcedTea 2.5.5) (7u79-2.5.5-0ubuntu0.12.04.1)
OpenJDK 64-Bit Server VM (build 24.79-b02, mixed mode)

I try to create /tmp/yui_compress20150521-2184-1p6a0d3 file then rerun the command above and it works. I think maybe it is bug
