Importurl

The Importurl task will download a file, and import it's contents into the current project. The file can be in the form of a standard ant .xml project file, or a .jar/.zip file.

In the case of an .xml file, the file is downloaded, and imported as is. In this case, the file itself is the only thing downloaded (ie. no corresponding .properties files, or other build files are downloaded).

In the case of a .jar/.zip file, the file is downloaded and then decompressed. After decompression, the file 'build.xml' at the root level of the jar is imported. By importing a .jar/.zip file, one can package additional resources along with the build.xml file. However, you must be careful how you refer to these resources. The build.xml file must follow the same rules as any other file imported with the <import> task, in that references relative to the build.xml file must be made with the property: ant.file.<projectname> where <projectname> is the name of the project being imported, as specified in the project tag. Example:

    
    
        <project name="common">
            <basedir property="ant.dir.common" file="${ant.file.common}" />
            <property file="${ant.dir.common}/build.properties" />
        </project>

This task should be compatible with older versions of ant, but has only been tested with Ant 1.6.x. The underlying implementation is done using the Ivy dependency resolver software, and thus, it needs available to the same classloader that loads this task.

Parameters

Attribute	Description	Required
org	The organization that publishes the script.	Yes.
module	The name of the module which is to be fetched.	Yes.
ref	The revision of the module to be fetched.	No. Defaults to "latest.integration". See the ivy details for more information on the possible wildcarding that can be used for this value.
type	The type of file to be downloaded	No. Defaults to 'jar'. Can be any file extension. However, unless the type is 'xml', the file is assumed to be a compressed file, expandable by ant's <expand> task (which is aliased to unjar, unzip).
ivyConfUrl	The URL of an ivy configuration file to use. We will use the default resolver in this file to find the requested resource.	No. Defaults to the IvyRepResolver.
ivyConfFile	The path of an ivy configuration file to use. We will use the default resolver in this file to find the requested resource.	No. Defaults to the IvyRepResolver.
repositoryUrl	The URL base of the repository to use. This results in using Ivy's URLResolver to resolve the requested resource.	No. Defaults to the IvyRepResolver.
repositoryDir	The file base of the repository to use. This results in using Ivy's FileSystemResolver to resolve the requested resource.	No. Defaults to the IvyRepResolver.
artifactPattern	The pattern used to find artifacts in the repository.	No. If repositoryUrl or repositoryDir are specified, this defaults to the standard repository pattern: "/[org]/[module]/[ext]s/[module]-[revision].[ext]". Please see the ivy documentation for more information on the contents of this pattern.

Example

    
    <antcontrib:importurl org="antcontrib"
                             module="common"
                             rev="3.2" />

would look for the file "antcontrib/common/jars/common-3.2.jar" in the IvyRep repository.

    
    <antcontrib:importurl org="antcontrib"
                             module="common"
                             rev="3.2" 
                             type="xml" />

would look for the file "antcontrib/common/jars/common-3.2.xml" in the IvyRep repository.

    
    <antcontrib:importurl repositoryUrl="http://www.antcontrib.org/ivyrep"
                             org="antcontrib"
                             module="common"
                             rev="3.2" />

would look for the located at "http://www.antcontrib.org/ivyrep/antcontrib/common/jars/common-3.2.jar"

The following build.xml may be packaged into a .jar with it's corresponding build.properties file:

    
    <project name="common">
    <basedir property="ant.dir.common" file="${ant.file.common}" />
    <property file="${ant.dir.common}/build.properties" />
    </project>
