Method Detail

init

protected abstract boolean init()
                         throws Exception

Method to initialize the mojo before doing any concrete actions.

Note: The method is invoked before the doAction() method.

Returns:

true if mojo is well initialize and something has to be done in the doAction() method, false otherwise.

Throws:

Exception - if any

doAction

protected abstract void doAction()
                          throws Exception

Do plugin action.

The method execute() invoke this method only and only if :

• checkPackaging() returns true.
• method init() returns true.

Throws:

Exception - if any

execute

public void execute()
             throws org.apache.maven.plugin.MojoExecutionException,
                    org.apache.maven.plugin.MojoFailureException

Specified by:

execute in interface org.apache.maven.plugin.Mojo

Throws:

org.apache.maven.plugin.MojoExecutionException

org.apache.maven.plugin.MojoFailureException

checkPackaging

protected boolean checkPackaging()

Check if the project packaging is acceptable for the mojo.

By default, accept all packaging types.

Note: This method is the first instruction to be executed in the execute().

Tip: There is two method to simplify the packaging check : acceptPackaging(org.nuiton.plugin.Plugin.Packaging[]) and rejectPackaging(org.nuiton.plugin.Plugin.Packaging[])

Returns:

true if can execute the goal for the packaging of the project, false otherwise.

acceptPackaging

protected boolean acceptPackaging(Plugin.Packaging... packages)

Accept the project's packaging between some given.

Parameters:

packages - the accepted packaging

Returns:

true if the project's packagin is one of the given ones.

rejectPackaging

protected boolean rejectPackaging(Plugin.Packaging... packages)

Accept the project's packaging if not in given one.

Parameters:

packages - the rejecting packagings

Returns:

true if the project's packaging is not in the given ones.

copyFile

                     File destFile)
              throws org.apache.maven.plugin.MojoExecutionException

Copy a file to a given locationand logging.

Parameters:

srcFile - represents the file to copy.

destFile - file name of destination file.

Throws:

org.apache.maven.plugin.MojoExecutionException - with a message if an error occurs.

Parameters:

destFile - location where to write the content

encoding - the enconding of the file

Throws:

IOException - if any pb while writing the content into the file

isFileNewerThanPomFile

protected boolean isFileNewerThanPomFile(File f)

Test if a file exists and is newer than the pom file.

Parameters:

f - the file to test

Returns:

true if file exists and is newer than the pom file, false otherwise.
