Constructor Detail

Groovy

public Groovy()

Method Detail

setFork

public void setFork(boolean fork)

Should the script be executed using a forked process. Defaults to false.

Overrides:

setFork in class Java

Parameters:

fork - true if the script should be executed in a forked process

setUseGroovyShell

public void setUseGroovyShell(boolean useGroovyShell)

Should a new GroovyShell be used when forking. Special variables won't be available but you don't need Ant in the classpath.

Parameters:

useGroovyShell - true if GroovyShell should be used to run the script directly

setIncludeAntRuntime

public void setIncludeAntRuntime(boolean includeAntRuntime)

Should the system classpath be included on the classpath when forking. Defaults to true.

Parameters:

includeAntRuntime - true if the system classpath should be on the classpath

setStacktrace

public void setStacktrace(boolean stacktrace)

Enable compiler to report stack trace information if a problem occurs during compilation.

Parameters:

stacktrace - set to true to enable stacktrace reporting

setSrc

public void setSrc(File srcFile)

Set the name of the file to be run. The folder of the file is automatically added to the classpath. Required unless statements are enclosed in the build file

Parameters:

srcFile - the file containing the groovy script to execute

addText

public void addText(String txt)

Set an inline command to execute. NB: Properties are not expanded in this text.

Parameters:

txt - the inline groovy commands to execute

addFileset

public void addFileset(FileSet set)

Adds a set of files (nested fileset attribute).

Parameters:

set - the fileset representing source files

setOutput

public void setOutput(File output)

Set the output file; optional, defaults to the Ant log.

Overrides:

setOutput in class Java

Parameters:

output - the output file

setAppend

public void setAppend(boolean append)

Whether output should be appended to or overwrite an existing file. Defaults to false.

Overrides:

setAppend in class Java

Parameters:

append - set to true to append

setClasspath

public void setClasspath(Path classpath)

Sets the classpath for loading.

Overrides:

setClasspath in class Java

Parameters:

classpath - The classpath to set

createClasspath

public Path createClasspath()

Returns a new path element that can be configured. Gets called for instance by Ant when it encounters a nested <classpath> element.

Overrides:

createClasspath in class Java

Returns:

the resulting created path

setClasspathRef

public void setClasspathRef(Reference ref)

Set the classpath for loading using the classpath reference.

Overrides:

setClasspathRef in class Java

Parameters:

ref - the refid to use

getClasspath

public Path getClasspath()

Gets the classpath.

Returns:

Returns a Path

setConfigscript

public void setConfigscript(String configscript)

Sets the configuration script for the groovy compiler configuration.

Parameters:

configscript - path to the configuration script

setIndy

public void setIndy(boolean indy)

Sets the indy flag to enable or disable invokedynamic

Parameters:

indy - true means invokedynamic support is active

setScriptBaseClass

public void setScriptBaseClass(String scriptBaseClass)

Set the script base class name

Parameters:

scriptBaseClass - the name of the base class for scripts

execute

public void execute()
             throws BuildException

Load the file and then execute it

Overrides:

execute in class Java

Throws:

BuildException

createArg

public Commandline.Argument createArg()

Overrides:

createArg in class Java

runStatements

protected void runStatements(Reader reader,
                 PrintStream out)
                      throws IOException

Read in lines and execute them.

Parameters:

reader - the reader from which to get the groovy source to exec

out - the outputstream to use

Throws:

IOException - if something goes wrong

execGroovy

protected void execGroovy(String txt,
              PrintStream out)

Exec the statement.

printResults

protected void printResults(PrintStream out)

print any results in the statement.

Parameters:

setContextClassLoader

public void setContextClassLoader(boolean contextClassLoader)

Setting to true will cause the contextClassLoader to be set with the classLoader of the shell used to run the script. Not used if fork is true. Not allowed when running from Maven but in that case the context classLoader is set appropriately for Maven.

Parameters:

contextClassLoader - set to true to set the context classloader
