Creates a manifest file.
This task can be used to write a Manifest file, optionally replacing or updating an existing file.
Manifests are processed according to the Jar file specification.. Specifically, a manifest element consists of a set of attributes and sections. These sections in turn may contain attributes. Note in particular that this may result in manifest lines greater than 72 bytes being wrapped and continued on the next line.
Attribute | Description | Required |
file | the manifest-file to create/update. | Yes |
mode | One of "update" or "replace", default is "replace". | No |
encoding | The encoding used to read the existing manifest when updating. | No, defaults to UTF-8 encoding. |
One attribute for the manifest file. Those attributes that are not nested into a section will be added to the "Main" section.
Attribute | Description | Required |
name | the name of the attribute. | Yes |
value | the value of the attribute. | Yes |
A manifest section - you can nest attribute elements into sections.
Attribute | Description | Required |
name | the name of the section. | No, if omitted it will be assumed to be the main section. |
<manifest file="MANIFEST.MF"> <attribute name="Built-By" value="${user.name}"/> <section name="common"> <attribute name="Specification-Title" value="Example"/> <attribute name="Specification-Version" value="${version}"/> <attribute name="Specification-Vendor" value="Example Organization"/> <attribute name="Implementation-Title" value="common"/> <attribute name="Implementation-Version" value="${version} ${TODAY}"/> <attribute name="Implementation-Vendor" value="Example Corp."/> </section> <section name="common/class1.class"> <attribute name="Sealed" value="false"/> </section> </manifest>
Creates or replaces the file MANIFEST.MF. Note that the Built-By
attribute will take the value of the Ant property ${user.name}. The
same is true for the ${version} and ${TODAY} properties. This example
produces a MANIFEST.MF that contains
package
version identification for the package common
.
The manifest produced by the above would look like this:
Manifest-Version: 1.0
Built-By: bodewig
Created-By: Apache Ant 1.5alpha
Name: common
Specification-Title: Example
Specification-Vendor: Example Organization
Implementation-Vendor: Example Corp.
Specification-Version: 1.1
Implementation-Version: 1.1 February 19 2002
Implementation-Title: common
Name: common/class1.class
Sealed: false
