public class Groovyc extends MatchingTask
Compiles Groovy source files using Ant.
Typically involves using Ant from the command-line and an Ant build file such as:
<?xml version="1.0"?> <project name="MyGroovyBuild" default="compile"> <property name="groovy.home" location="/Path/To/Groovy"/> <property name="groovy.version" value="X.Y.Z"/> <taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc"> <classpath> <fileset file="${groovy.home}/lib/groovy-${groovy.version}.jar"/> <fileset file="${groovy.home}/lib/groovy-ant-${groovy.version}.jar"/> </classpath> </taskdef> <target name="compile" description="compile groovy sources"> <groovyc srcdir="src" destdir="bin" fork="true" listfiles="true" includeantruntime="false"> <classpath> <fileset dir="${groovy.home}/lib" includes="groovy-*${groovy.version}.jar" excludes="groovy-ant-${groovy.version}.jar"/> </classpath> </groovyc> </target> </project>
This task can take the following arguments:
When this task executes, it will recursively scan srcdir and destdir looking for Groovy source files to compile. This task makes its compile decision based on timestamp.
A more elaborate build file showing joint compilation:
<?xml version="1.0"?> <project name="MyJointBuild" default="compile"> <property name="groovy.home" location="/Path/To/Groovy"/> <property name="groovy.version" value="X.Y.Z"/> <path id="classpath.main"> <fileset dir="${groovy.home}/lib"> <include name="groovy-*${groovy.version}.jar"/> <exclude name="groovy-ant-${groovy.version}.jar"/> </fileset> </path> <taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc"> <classpath> <fileset file="${groovy.home}/lib/groovy-${groovy.version}.jar"/> <fileset file="${groovy.home}/lib/groovy-ant-${groovy.version}.jar"/> </classpath> </taskdef> <target name="clean"> <delete dir="bin" failonerror="false"/> </target> <target name="compile" depends="clean" description="compile java and groovy sources"> <mkdir dir="bin"/> <groovyc srcdir="src" destdir="bin" stubdir="stubs" keepStubs="true" fork="true" includeantruntime="false" classpathref="classpath.main"> <javac debug="true" source="1.8" target="1.8"/> </groovyc> </target> </project>
Based on the implementation of the Javac task in Apache Ant.
Can also be used from AntBuilder to allow the build file to be scripted in Groovy.

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
.
forceLookupUnnamedFiles
- should unnamed source files be searched for on the classpathIf true forks the Groovy compiler. Default is false.
f
- "true|false|on|off|yes|no"This property controls whether to include the destination classes directory in the classpath given to the compiler. The default value is "true".
includeDestClasses
- the value to use.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.
include
- if true, includes Ant's own classpath in the classpathIf true, includes the Java runtime libraries in the classpath. Default is false.
include
- if true, includes the Java runtime libraries in the classpathLegacy method to set the indy flag (only true is allowed)
indy
- true means invokedynamic support is activeThe JDK Home to use when forked. Ignored if "executable" is specified.
home
- the java.home value to use, default is the current JDK's homeSet the keepStubs flag. Defaults to false. Set to true for debugging. Ignored when forked.
keepStubs
- should stubs be retainedIf true, list the source files being handed off to the compiler. Default is false.
list
- if true list the source filesThe initial size of the memory for the underlying VM if javac is run externally; ignored otherwise. Defaults to the standard VM memory setting. (Examples: 83886080, 81920k, or 80m)
memoryInitialSize
- string to pass to VMThe maximum size of the memory for the underlying VM if javac is run externally; ignored otherwise. Defaults to the standard VM memory setting. (Examples: 83886080, 81920k, or 80m)
memoryMaximumSize
- string to pass to VMIf true, generates metadata for reflection on method parameter names (jdk8+ only). Defaults to false.
parameters
- set to true to generate metadata.If true, enable preview Java features (JEP 12) (jdk12+ only).
previewFeatures
- set to true to enable preview features
proceed
- inverse of failonerrorSet the base script class name for the scripts (must derive from Script)

- the source pathAdds a reference to a source path defined elsewhere.
r
- a reference to a source pathSet the source directories to find the source Java files.
srcDir
- the source directories as a pathEnable compiler to report stack trace information if a problem occurs during compilation. Default is false.
Set the stub directory into which the Java source stub files should be generated. The directory need not exist and will not be deleted automatically - though its contents will be cleared unless 'keepStubs' is true. Ignored when forked.
stubDir
- the stub directorySets the bytecode compatibility level. The parameter can take one of the values in CompilerConfiguration.ALLOWED_JDKS.
version
- the bytecode compatibility levelThe property to set on compilation success. This property will not be set if the compilation fails, or if there are no files to compile.
updatedProperty
- the property name to use.Enable verbose compiling which will display which files are being compiled. Default is false.
