execute
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 benull
.- Returns:
- The result of the Maven invocation, never
null
. - Throws:
MavenInvocationException
- if cannot configure correctly execution parameters
-
getLocalRepositoryDirectory
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 thesettings.xml
.
-
getWorkingDirectory
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
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
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
Invoker setMavenHome(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 propertymaven.home
and the environment variableM2_HOME
.- Parameters:
mavenHome
- The path to the base directory of the Maven installation, may benull
to use the default Maven installation.- Returns:
- This invoker instance.
-
getMavenExecutable
File getMavenExecutable()
Get the customized File of the Maven executable.- Returns:
- the custom Maven executable, otherwise
null
-
setMavenExecutable
Invoker setMavenExecutable(File mavenExecutable)
mavenExecutable
can either be a file relative to ${maven.home}/bin/ or an absolute file.- Parameters:
mavenExecutable
- the executable- Returns:
- This invoker instance
-
setLocalRepositoryDirectory
Invoker setLocalRepositoryDirectory(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 ornull
to use the location from thesettings.xml
.- Returns:
- This invoker instance.
-
setLogger
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 benull
to use a default logger.- Returns:
- This invoker instance.
-
setWorkingDirectory
Invoker setWorkingDirectory(File workingDirectory)
Sets the working directory for the Maven invocation.- Parameters:
workingDirectory

to derive the working directory from the base directory of the processed POM.- Returns:
- This invoker instance.
-
setInputStream
Invoker setInputStream(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 benull
if not required.- Returns:
- This invoker instance.
-
setOutputHandler
Invoker setOutputHandler(InvocationOutputHandler outputHandler)
Sets the handler used to capture the standard output from the Maven build.- Parameters:
outputHandler
