[Java] Class Groovyc

public class Groovyc
extends MatchingTask

Compiles Groovy source files. This task can take the following arguments:

And these nested tasks: Of these arguments, the srcdir and destdir are required.

When this task executes, it will recursively scan srcdir and destdir looking for Groovy source files to compile. This task makes its compile decision based on timestamp.

Based heavily on the Javac implementation in Ant.

setFailonerror

public void setFailonerror(boolean fail)
Indicates whether the build will continue even if there are compilation errors; defaults to true.
Parameters:
fail - if true halt the build on failure

setForceLookupUnnamedFiles

public void setForceLookupUnnamedFiles(boolean forceLookupUnnamedFiles)
Set the forceLookupUnnamedFiles flag. Defaults to false. The Groovyc Ant task is frequently used in the context of a build system that knows the complete list of source files to be compiled. In such a context, it is wasteful for the Groovy compiler to go searching the classpath when looking for source files and hence by default the Groovyc Ant task calls the compiler in a special mode with such searching turned off. If you wish the compiler to search for source files then you need to set this flag to true.
Parameters:
forceLookupUnnamedFiles - should unnamed source files be searched for on the classpath

setFork

public void setFork(boolean f)
If true forks the Groovy compiler. Default is false.
Parameters:
f - "true|false|on|off|yes|no"

setIncludeDestClasses

This property controls whether to include the destination classes directory in the classpath given to the compiler. The default value is "true".
Parameters:
includeDestClasses - the value to use.

setIncludeantruntime

public void setIncludeantruntime(boolean include)
If true, includes Ant's own classpath in the classpath. Default is true. If setting to false and using groovyc in conjunction with AntBuilder you might need to explicitly add the Groovy jar(s) to the groovyc classpath using a nested classpath task.
Parameters:
include - if true, includes Ant's own classpath in the classpath

setIncludejavaruntime

public void setIncludejavaruntime(boolean include)
If true, includes the Java runtime libraries in the classpath. Default is false.

public void setTargetBytecode(String version)
Sets the bytecode compatibility mode
