Module: Juicer::Minifyer::JavaBase

Includes:
Binary
Included in:
ClosureCompiler, YuiCompressor
Defined in:
lib/juicer/minifyer/java_base.rb

Overview

Provides an interface to Java based compressor libraries using Juicer::Shell::Binary.

The compressor is invoked using the java binary and the compressor jar file.

Providing the Jar file can be done in several ways. The following directories are searched (in preferred order)

1. The directory specified by the option :bin_path
2. The directory specified by the environment variable, if set
3. Current working directory

Name of environment variable is decided by including classes self.env_name constant.

For more information on how the Jar is located, see Juicer::Minify::JavaMinifyer.locate_jar
