Field Detail

ROLE

public static final java.lang.String ROLE

The role name used to register implementations of this interface within Plexus.

userHome

public static final java.lang.String userHome

Deprecated. Query this property by yourself, this has nothing to do with invoking Maven and as such does not belong into this API!

Method Detail

execute

public InvocationResult execute(InvocationRequest request)
                         throws MavenInvocationException

Executes Maven using the parameters specified by the given invocation request. Parameters not specified by the invocation request will be derived from the state of this invoker instance. In case both the invoker instance and the invocation request provide a value for a particular option, the value from the invocation request dominates.

Parameters:

request - The invocation request to execute, must not be null.

Returns:

The result of the Maven invocation, never null.

Throws:

MavenInvocationException

getLocalRepositoryDirectory

public java.io.File getLocalRepositoryDirectory()

Gets the path to the base directory of the local repository to use for the Maven invocation.

Returns:

The path to the base directory of the local repository or null to use the location from the settings.xml.

getWorkingDirectory

public java.io.File getWorkingDirectory()

Gets the working directory for the Maven invocation.

Returns:

The working directory for the Maven invocation or null if the working directory is derived from the base directory of the processed POM.

getLogger

public InvokerLogger getLogger()

Gets the logger used by this invoker to output diagnostic messages.

Returns:

The logger used by this invoker to output diagnostic messages, never null.

getMavenHome

public java.io.File getMavenHome()

Gets the path to the base directory of the Maven installation used to invoke Maven.

Returns:

The path to the base directory of the Maven installation or null if using the default Maven installation.

setMavenHome

public Invoker setMavenHome(java.io.File mavenHome)

Sets the path to the base directory of the Maven installation used to invoke Maven. This parameter may be left unspecified to use the default Maven installation which will be discovered by evaluating the system property maven.home and the environment variable M2_HOME.

Parameters:

mavenHome - The path to the base directory of the Maven installation, may be null to use the default Maven installation.

Returns:

This invoker instance.

setLocalRepositoryDirectory

public Invoker setLocalRepositoryDirectory(java.io.File localRepositoryDirectory)

Sets the path to the base directory of the local repository to use for the Maven invocation.

Parameters:

localRepositoryDirectory - The path to the base directory of the local repository or null to use the location from the settings.xml.

Returns:

This invoker instance.

setLogger

public Invoker setLogger(InvokerLogger logger)

Sets the logger used by this invoker to output diagnostic messages.

Parameters:

logger - The logger used by this invoker to output diagnostic messages, may be null to use a default logger.

Returns:

This invoker instance.

setWorkingDirectory

public Invoker setWorkingDirectory(java.io.File workingDirectory)

Sets the working directory for the Maven invocation.

Parameters:

workingDirectory - The working directory for the Maven invocation, may be null to derive the working directory from the base directory of the processed POM.

Returns:

This invoker instance.

setInputStream

public Invoker setInputStream(java.io.InputStream inputStream)

Sets the input stream used to provide input for the invoked Maven build. This is in particular useful when invoking Maven in interactive mode.

Parameters:

inputStream - The input stream used to provide input for the invoked Maven build, may be null if not required.

Returns:

This invoker instance.

setOutputHandler

public Invoker setOutputHandler(InvocationOutputHandler outputHandler)

Sets the handler used to capture the standard output from the Maven build.

Parameters:

outputHandler - The output handler, may be null if the output is not of interest.

Returns:

This invoker instance.

setErrorHandler

public Invoker setErrorHandler(InvocationOutputHandler errorHandler)

Sets the handler used to capture the error output from the Maven build.

Parameters:

errorHandler - The error handler, may be null if the output is not of interest.

Returns:

This invoker instance.
