execute

protected void execute()
                throws ArchiverException,
IOException

Specified by:

execute in class AbstractArchiver

Throws:

ArchiverException

IOException

finalizeZipOutputStream

protected void finalizeZipOutputStream(ConcurrentJarCreator zOut)
                                throws IOException,
ArchiverException

Throws:

IOException

ArchiverException

addResources

protected final void addResources(ResourceIterator resources,
 ConcurrentJarCreator zOut)
                           throws IOException,
ArchiverException

Add the given resources.

Parameters:

resources - the resources to add

zOut - the stream to write to

Throws:

IOException

ArchiverException

zipFile

protected void zipFile(org.apache.commons.compress.parallel.InputStreamSupplier in,
 ConcurrentJarCreator zOut,
 String vPath,
 long lastModified,
 File fromArchive,
 int mode,
 String symlinkDestination,
 boolean addInParallel)
                throws IOException,
ArchiverException

Adds a new entry to the archive, takes care of duplicates as well.

Parameters:

in - the stream to read data for the entry from.

zOut - the stream to write to.

vPath - the name this entry shall have in the archive.

lastModified - last modification time for the entry.

fromArchive - the original archive we are copying this

symlinkDestination -

addInParallel - Indicates if the entry should be add in parallel. If set to false it is added synchronously. If the entry is symbolic link this parameter is ignored.

Throws:

IOException

ArchiverException

zipFile

protected void zipFile(ArchiveEntry entry,
 ConcurrentJarCreator zOut,
 String vPath)
                throws IOException,
ArchiverException

Method that gets called when adding from java.io.File instances.

This implementation delegates to the six-arg version.

Parameters:

entry - the file to add to the archive

zOut - the stream to write to

vPath - the name this entry shall have in the archive

Throws:

IOException

ArchiverException

setZipEntryTime

protected void setZipEntryTime(org.apache.commons.compress.archivers.zip.ZipArchiveEntry zipEntry,
 long lastModifiedTime)

Set the ZipEntry dostime using the date if specified otherwise the original time.

Zip archives store file modification times with a granularity of two seconds, so the times will either be rounded up or down. If you round down, the archive will always seem out-of-date when you rerun the task, so the default is to round up. Rounding up may lead to a different type of problems like JSPs inside a web archive that seem to be slightly more recent than precompiled pages, rendering precompilation useless. plexus-archiver chooses to round up.

Parameters:

zipEntry - to set the last modified time

lastModifiedTime - to set in the zip entry only if AbstractArchiver.getLastModifiedTime() returns null

zipDir

protected void zipDir(org.codehaus.plexus.components.io.resources.PlexusIoResource dir,
 ConcurrentJarCreator zOut,
 String vPath,
 int mode,
 String encodingToUse)
               throws IOException

Throws:

IOException

createEmptyZip

protected boolean createEmptyZip(File zipFile)
                          throws ArchiverException

Create an empty zip file

Parameters:

zipFile - The file

Returns:

true for historic reasons

Throws:

ArchiverException

cleanUp

protected void cleanUp()
                throws IOException

Do any clean up necessary to allow this instance to be used again.

When we get here, the Zip file has been closed and all we need to do is to reset some globals.

This method will only reset globals that have been changed during execute(), it will not alter the attributes or nested child elements. If you want to reset the instance so that you can later zip a completely different set of files, you must use the reset method.

Overrides:

cleanUp in class AbstractArchiver

Throws:

IOException

See Also:

• reset()

reset

public void reset()

Makes this instance reset all attributes to their default values and forget all children.

• cleanUp()

initZipOutputStream

protected void initZipOutputStream(ConcurrentJarCreator zOut)
                            throws ArchiverException,
IOException

method for subclasses to override

Parameters:

zOut - The output stream

Throws:

ArchiverException

IOException

isSupportingForced

public boolean isSupportingForced()

method for subclasses to override

Specified by:

isSupportingForced in interface Archiver

Overrides:

isSupportingForced in class AbstractArchiver

Returns:

true, if the archiver does support uptodate checks, false otherwise

See Also:

• Archiver.setForced(boolean)
• Archiver.isForced()

revert

protected boolean revert(StringBuffer messageBuffer)

Overrides:

revert in class AbstractArchiver

close

protected void close()
              throws IOException

Specified by:

close in class AbstractArchiver

Throws:

IOException

getArchiveType

protected String getArchiveType()

Specified by:

getArchiveType in class AbstractArchiver

normalizeLastModifiedTime

protected FileTime normalizeLastModifiedTime(FileTime lastModifiedTime)

Description copied from class: AbstractArchiver

Normalize last modified time value to get reproducible archive entries, based on archive binary format.

tar uses UTC timestamp, but zip uses local time then requires tweaks to make the value reproducible whatever the current timezone is.

Overrides:

normalizeLastModifiedTime in class AbstractArchiver

Parameters:

lastModifiedTime - The last modification time

Returns:

The normalized last modification time
