  - ### Method Detail

    - #### setProperty

          public void setProperty​(java.lang.String property)

      The name of the property in which the location of library is stored.
      Parameters:
        `property` - The name of the property in which the location of library is stored.

    - #### setCheckExtension

          public void setCheckExtension​(boolean checkExtension)

      Check nested libraries for extensions
      Parameters:
        `checkExtension` - if true, libraries returned by nested resolvers should be checked to see if they supply extension.

    - #### setFailOnError

          public void setFailOnError​(boolean failOnError)

      Set whether to fail if error.
      Parameters:
        `failOnError` - if true, failure to locate library should fail build.

    - #### addConfiguredLocation

          public void addConfiguredLocation​(LocationResolver loc)

      Adds location resolver to look for a library in a location relative to project directory.
      Parameters:
        `loc` - the resolver location to search.

    - #### addConfiguredUrl

          public void addConfiguredUrl​(URLResolver url)

      Adds a URL resolver to download a library from a URL to a local file.
      Parameters:
        `url` - the URL resolver from which to download the library

    - #### addConfiguredAnt

          public void addConfiguredAnt​(AntResolver ant)

      Adds Ant resolver to run an Ant build file to generate a library.
      Parameters:
        `ant` - the AntResolver to generate the library.

    - #### addConfiguredExtension

          public void addConfiguredExtension​(ExtensionAdapter extension)

      Set the Extension looking for.
      Parameters:
        `extension` - Set the Extension looking for.

    - #### execute

          public void execute()
                       throws BuildException

      Execute the task.
