public abstract class AbstractProcessRemoteResourcesMojo extends org.apache.maven.plugin.AbstractMojo

Pull down resourceBundles containing remote resources and process the resources contained inside. When that is done, the resources are injected into the current (in-memory) Maven project, making them available to the process-resources phase.

Resources that end in ".vm" are treated as Velocity templates. For those, the ".vm" is stripped off for the final artifact name and it's fed through Velocity to have properties expanded, conditions processed, etc...

Resources that don't end in ".vm" are copied "as is".

This is a support abstract class, with two non-aggregating and aggregating implementations.

    • filterDelimiters

      @Parameter protected List<String> filterDelimiters

      In cases where a local resource overrides one from a remote resource bundle, that resource should be filtered if the resource set specifies it. In those cases, this parameter defines the list of delimiters for filterable expressions. These delimiters are specified in the form 'beginToken*endToken'. If no '*' is given, the delimiter is assumed to be the same for start and end.

      So, the default filtering delimiters might be specified as:

       <delimiters>
         <delimiter>${*}</delimiter>
         <delimiter>@</delimiter>
       </delimiters>
       
      Since the '@' delimiter is the same on both ends, we don't need to specify '@*@' (though we can).

      1.5
    • properties

      @Parameter protected Map<String,String> properties
      Additional properties to be passed to Velocity. Several properties are automatically added:
      • project - the current MavenProject
      • projects - the list of dependency projects
      • projectsSortedByOrganization - the list of dependency projects sorted by organization
      • projectTimespan - the timespan of the current project (requires inceptionYear in pom)
      • locator - the ResourceManager that can be used to retrieve additional resources
      See the javadoc for MavenProject for information about the properties on the MavenProject.
    • includeProjectProperties

      @Deprecated @Parameter(defaultValue="false") protected boolean includeProjectProperties
      Deprecated.
      as Maven Project is available in Velocity context we can simply use $project.properties.propertyName
      Whether to include properties defined in the project when filtering resources.
      Since:
      1.2
    • velocityFilterInMemoryThreshold

      @Deprecated @Parameter(defaultValue="5242880") protected int velocityFilterInMemoryThreshold
      Deprecated.
      not used anymore
      When the result of velocity transformation fits in memory, it is compared with the actual contents on disk to eliminate unnecessary destination file overwrite. This improves build times since further build steps typically rely on the modification date.
      Since:
      1.6

    • resolveScopes

      @Parameter protected String[] resolveScopes
      When resolving project dependencies, specify the scopes to include. The default is the same as "includeScope" if there are no exclude scopes set. Otherwise, it defaults to "test" to grab all the dependencies so the exclude filters can filter out what is not needed.
