Method Detail

setWhenempty

public void setWhenempty(Zip.WhenEmpty we)

Description copied from class: Zip

Sets behavior of the task when no files match. Possible values are: fail (throw an exception and halt the build); skip (do not create any archive, but issue a warning); create (make an archive with no entries). Default for zip tasks is skip; for jar tasks, create.

Overrides:

setWhenempty in class Zip

setJarfile

public void setJarfile(java.io.File jarFile)

Deprecated. Use setDestFile(File) instead

setIndex

public void setIndex(boolean flag)

Set whether or not to create an index list for classes. This may speed up classloading in some cases.

setManifestEncoding

public void setManifestEncoding(java.lang.String manifestEncoding)

Set whether or not to create an index list for classes. This may speed up classloading in some cases.

addConfiguredManifest

public void addConfiguredManifest(Manifest newManifest)
                           throws ManifestException

Allows the manifest for the archive file to be provided inline in the build file rather than in an external file.

Parameters:

newManifest -

Throws:

ManifestException

setManifest

public void setManifest(java.io.File manifestFile)

The manifest file to use. This can be either the location of a manifest, or the name of a jar added through a fileset. If its the name of an added jar, the task expects the manifest to be in the jar at META-INF/MANIFEST.MF.

Parameters:

manifestFile - the manifest file to use.

setFilesetmanifest

public void setFilesetmanifest(Jar.FilesetManifestConfig config)

Behavior when a Manifest is found in a zipfileset or zipgroupfileset file. Valid values are "skip", "merge", and "mergewithoutmain". "merge" will merge all of manifests together, and merge this into any other specified manifests. "mergewithoutmain" merges everything but the Main section of the manifests. Default value is "skip". Note: if this attribute's value is not "skip", the created jar will not be readable by using java.util.jar.JarInputStream

Parameters:

config - setting for found manifest behavior.

addMetainf

public void addMetainf(ZipFileSet fs)

Adds a zipfileset to include in the META-INF directory.

Parameters:

fs - zipfileset to add

addConfiguredIndexJars

public void addConfiguredIndexJars(Path p)

Since:

zipFile

protected void zipFile(java.io.InputStream is,
                       ZipOutputStream zOut,
                       java.lang.String vPath,
                       long lastModified,

                       int mode)
                throws java.io.IOException

Overridden from Zip class to deal with manifests and index lists.

Overrides:

zipFile in class Zip

Parameters:

is - 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 entry from, will be null if we are not copying from an archive.

mode - the Unix permissions to set.

getResourcesToAdd

protected Zip.ArchiveState getResourcesToAdd(FileSet[] filesets,
                                             java.io.File zipFile,
                                             boolean needsUpdate)
                                      throws BuildException

Collect the resources that are newer than the corresponding entries (or missing) in the original archive.

If we are going to recreate the archive instead of updating it, all resources should be considered as new, if a single one is. Because of this, subclasses overriding this method must call super.getResourcesToAdd and indicate with the third arg if they already know that the archive is out-of-date.

Overrides:

getResourcesToAdd in class Zip

Parameters:

filesets - The filesets to grab resources from

zipFile - intended archive file (may or may not exist)

needsUpdate - whether we already know that the archive is out-of-date. Subclasses overriding this method are supposed to set this value correctly in their call to super.getResourcesToAdd.

Returns:

an array of resources to add for each fileset passed in as well as a flag that indicates whether the archive is uptodate.

Throws:

BuildException - if it likes

createEmptyZip

protected boolean createEmptyZip(java.io.File zipFile)
                          throws BuildException

Description copied from class: Zip

Create an empty zip file

Overrides:

createEmptyZip in class Zip

Returns:

true for historic reasons

BuildException

cleanUp

protected void cleanUp()

Make sure we don't think we already have a MANIFEST next time this task gets executed.

Overrides:

cleanUp in class Zip

See Also:

Zip.cleanUp()

reset

public void reset()

reset to default values.

Overrides:

reset in class Zip

writeIndexLikeList

                                        java.util.List files,
                                        java.io.PrintWriter writer)
                                 throws java.io.IOException

Writes the directory entries from the first and the filenames from the second list to the given writer, one entry per line.

findJarName

protected static final java.lang.String findJarName(java.lang.String fileName,
                                                    java.lang.String[] classpath)

try to guess the name of the given file.

If this jar has a classpath attribute in its manifest, we can assume that it will only require an index of jars listed there. try to find which classpath entry is most likely the one the given file name points to.

In the absence of a classpath attribute, assume the other files will be placed inside the same directory as this jar and use their basename.

if there is a classpath and the given file doesn't match any of its entries, return null.

Ant 1.7

grabFilesAndDirs

protected static final void grabFilesAndDirs(java.lang.String file,
                                             java.util.List dirs,
                                             java.util.List files)
