Groovyc compiler: 

 compile.using(:groovyc)

You need to require ‘buildr/groovy/compiler’ if you need to use this compiler.

Used by default if .groovy files are found in the src/main/groovy directory (or src/test/groovy) and sets the target directory to target/classes (or target/test/classes).

Groovyc is a joint compiler, this means that when selected for a project, this compiler is used to compile both groovy and java sources. It’s recommended that Groovy sources are placed in the src/main/groovy directory, even though this compiler also looks in src/main/java

Groovyc accepts the following options:

  • :encoding — Encoding of source files
  • :verbose — Asks the compiler for verbose output, true when running in verbose mode.
  • :fork — Whether to execute groovyc using a spawned instance of the JVM; defaults to no
  • :memoryInitialSize — The initial size of the memory for the underlying VM, if using fork mode; ignored otherwise. 
                                      Defaults to the standard VM memory setting. (Examples: 83886080, 81920k, or 80m)
  • :memoryMaximumSize — The maximum size of the memory for the underlying VM, if using fork mode; ignored otherwise. 
                                      Defaults to the standard VM memory setting. (Examples: 83886080, 81920k, or 80m)
  • :listfiles — Indicates whether the source files to be compiled will be listed; defaults to no
  • :stacktrace — If true each compile error message will contain a stacktrace
  • :warnings — Issue warnings when compiling. True when running in verbose mode.
  • :debug — Generates bytecode with debugging information. Set from the debug 
                                      environment variable/global option.
  • :deprecation — If true, shows deprecation messages. False by default.
  • :optimise — Generates faster bytecode by applying optimisations to the program.
  • :source — Source code compatibility.
  • :target — Bytecode compatibility.
  • :javac — Hash of options passed to the ant javac task

The groovyc compiler jars are added to classpath at load time, if you want to customize artifact versions, you must set them on the 

     artifact_ns(Buildr::Groovy::Groovyc).groovy = '1.7.1'

namespace before this file is required.
