Trying to locally get ${local-plugin-name}${local-plugin-version} Looking in local @{plugin-src-dir} Plugin ${local-plugin-name}${local-plugin-version} deployed ! Ready to configure Tying to download ${download-plugin-name}${download-plugin-version} from the distribution site ... Using Forrest version : ${download-forrest-version} Plugin org.apache.forrest.plugin.output.pdf downloaded ! Ready to install Plugin org.apache.forrest.plugin.output.pdf was up-to-date ! Ready to configure Unable to download the "org.apache.forrest.plugin.output.pdf" plugin or an equivalent unversioned plugin from http://forrest.apache.org/plugins/ There are a number of possible causes for this: One possible problem is that you do not have write access to FORREST_HOME, in which case ask your system admin to install the required Forrest plugin as described below. A further possibility is that Forrest may be unable to connect to the plugin distribution server. Again the solution is to manually install the plugin. To manually install a plugin, download the plugin zip file from http://forrest.apache.org/plugins/ and extract it into C:\Development\apache-forrest-0.8\build\plugins/org.apache.forrest.plugin.output.pdf
