Overwrite read-only destination files.

EOL

Specifies what the end of line character are for use by the fixlastline attribute.

Binary

If this attribute is set to true, the task concatenates the files in a byte by byte fashion. If this attribute is false, concat will not normally work for binary files due to character encoding issues. If this option is set to true, the destfile attribute must be set, and the task cannot used nested text. Also the attributes encoding, outputencoding, filelastline cannot be used.

Filterbeforeconcat

If this attribute is set to true, the task applies the filterchain to each input after applying fixlastline. If this attribute is false, concat will apply the filterchain only once to the already concatenated inputs. Filtering of header and footer is not affected by this setting.

Granularity

The number of milliseconds leeway to give before deciding a file is out of date. This is needed because not every file system supports tracking the last modified time to the millisecond level. This can also be useful if source and target files live on separate machines with clocks being out of sync.

logerror

This attribute is used when you wish to see error output in Ant's log and you are redirecting output to a file/property. The error output will not be included in the output file/property. If you redirect error with the error or errorProperty attributes, this will have no effect.

Clonevm

If set to true, then all system properties and the bootclasspath of the forked JVM will be the same as those of the JVM running Ant.

Discardoutput

Whether output should completely be discarded. This setting is incompatible with any setting that redirects output to files or properties. If you set this to true error output will be discared as well unless you redirect error output to files, properties or enable logError.

Debuglevel

Keyword list to be appended to the -g command-line switch. Legal values are none or a comma-separated list of the following keywords: lines, vars, and source.

Verbose

Asks the compiler for verbose output.

Depend

Non-default level at which file compression should be performed. Valid values range from 0 (no compression/fastest) to 9 (maximum compression/slowest).

preserve0permissions

When updating an archive or adding entries from a different archive Ant will assume that a Unix permissions value of 0 (nobody is allowed to do anything to the file/directory) means that the permissions haven't been stored at all rather than real permissions and will instead apply its own default values.

useLanguageEncodingFlag

Whether to set the language encoding flag if the encoding is UTF-8. This setting doesn't have any effect if the encoding is not UTF-8.

createUnicodeExtraFields

Whether to create Unicode extra fields to store the file names a second time inside the entry's metadata.

fallbacktoUTF8

Whether to use UTF-8 and the language encoding flag instead of the specified encoding if a file name cannot be encoded using the specified encoding.

mergeClassPathAttributes

Whether to merge the Class-Path attributes found in different manifests (if merging manifests). If false, only the attribute of the last merged manifest will be preserved.

flattenAttributes

Whether to merge attributes occurring more than once in a section (this can only happen for the Class-Path attribute) into a single attribute.

zip64Mode

When to use Zip64 extensions for entries. The possible values are never, always and as-needed.
