Groovyc (groovy 2.4.15 API)

org.codehaus.groovy.ant.Groovyc

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" value="/Path/To/Groovy"/>
   <property name="groovy.version" value="X.Y.Z"/>
   <path id="groovy.classpath">
     <fileset dir="${groovy.home}/embeddable">
       <include name="groovy-all-${groovy.version}.jar" />
     </fileset>
   </path>
   <taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc" classpathref="groovy.classpath"/>

   <target name="compile" description="compile groovy sources">
     <groovyc srcdir="src" listfiles="true" classpathref="groovy.classpath"/>
   </target>
 </project>

This task can take the following arguments:

srcdir
scriptExtension
targetBytecode
destdir
sourcepath
sourcepathRef
classpath
classpathRef
listfiles
failonerror
proceed
memoryInitialSize
memoryMaximumSize
encoding
verbose
includeantruntime
includejavaruntime
fork
javaHome
executable
updatedProperty
errorProperty
includeDestClasses
jointCompilationOptions
stacktrace
indy
scriptBaseClass
stubdir
keepStubs
forceLookupUnnamedFiles
configscript

And these nested tasks:

javac

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.

A more elaborate build file showing joint compilation:

 <?xml version="1.0"?>
 <project name="MyJointBuild" default="compile">
   <property name="groovy.home" value="/Path/To/Groovy"/>
   <property name="groovy.version" value="X.Y.Z"/>

   <path id="groovy.classpath">
     <fileset dir="${groovy.home}/embeddable">
       <include name="groovy-all-${groovy.version}.jar" />
     </fileset>
   </path>

   <target name="clean" description="remove all built files">
     <delete dir="classes" />
   </target>

   <target name="compile" depends="init" description="compile java and groovy sources">
     <mkdir dir="classes" />
     <groovyc destdir="classes" srcdir="src" listfiles="true" keepStubs="true" stubdir="stubs">
       <javac debug="on" deprecation="true"/>
       <classpath>
         <fileset dir="classes"/>
         <path refid="groovy.classpath"/>
       </classpath>
     </groovyc>
   </target>

   <target name="init">
     <taskdef name="groovyc" classname="org.codehaus.groovy.ant.Groovyc" classpathref="groovy.classpath"/>
   </target>
 </project>

Based heavily on the Javac implementation in Ant.

Can also be used from AntBuilder to allow the build file to be scripted in Groovy.

    Sets the file encoding for generated files.
    Parameters:

    Sets the name of the java executable to use when invoking the compiler in forked mode, ignored otherwise.
    Parameters:

    Since:
    Groovy 1.8.7
  - 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
  - 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
  - public void setFork(boolean f)
    
    If true forks the Groovy compiler. Default is false.
    Parameters:
    f - "true|false|on|off|yes|no"
  - public void setIncludeDestClasses(boolean includeDestClasses)
    
    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.
  - 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
  - public void setIncludejavaruntime(boolean include)
    
    If true, includes the Java runtime libraries in the classpath. Default is false.
    Parameters:
    include - if true, includes the Java runtime libraries in the classpath
  - public void setIndy(boolean useIndy)
    
    Set the indy flag.

  - public void setJavaHome(File home)
    
    The JDK Home to use when forked. Ignored if "executable" is specified.
    Parameters:
    home - the java.home value to use, default is the current JDK's home
  - public void setKeepStubs(boolean keepStubs)
    
    Set the keepStubs flag. Defaults to false. Set to true for debugging. Ignored when forked.
    Parameters:
    keepStubs - should stubs be retained
  - public void setListfiles(boolean list)
    
    If true, list the source files being handed off to the compiler. Default is false.
    Parameters:
    list - if true list the source files
  - public void setMemoryInitialSize(String memoryInitialSize)
    
    The 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)
    Parameters:
    memoryInitialSize - string to pass to VM
  - public void setMemoryMaximumSize(String memoryMaximumSize)

    Parameters:
    memoryMaximumSize - string to pass to VM
  - public void setProceed(boolean proceed)
    
    Parameters:

    Enable compiler to report stack trace information if a problem occurs during compilation. Default is false.
  - public void setStubdir(File stubDir)
    
    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.
    Parameters:
    stubDir - the stub directory
  - public void setTargetBytecode(String version)
    
    Sets the bytecode compatibility mode
    Parameters:
    version - the bytecode compatibility mode

    The property to set on compilation success. This property will not be set if the compilation fails, or if there are no files to compile.
    Parameters:
    updatedProperty - the property name to use.
  - public void setVerbose(boolean verbose)
    
    Enable verbose compiling which will display which files are being compiled. Default is false.
