It cannot find the Apache MAVEN repo mirror. Make sure the system you're building on has Internet access, and, if you're behind a proxy server, that you've configured Maven to talk through the proxy server. It also could be that that particular mirror was having issues when you tried to build, so just try it, again. Or try pointing at a different Maven repo mirror. But, that's not a Guacamole issue, per se, it's a generic Maven issue because Maven cannot talk to the repository server to download the necessary components. > But, I got the war before this error. >> [INFO] Building war: >> /opt/guacamole-client-0.9.13-incubating/guacamole/target/guacamole-0.9.13-incubating.war Yes, the build of the core components completed successfully, but none of the extensions got built.

If possible help to to achieve > seamless clipboard redirection as it is the requirement. It is possible, yes. I use it every day. There are three things that you need to check to make sure Clipboard redirection works seamlessly:- Depending on your Linux distribution, you may need to install the specific freerdp-plugins package. I run CentOS 7, and it is called freerdp-plugins.- There are a handful of libraries built with guacamole server (guacd) that needs to be in the correct place on the server running guacd. When they are installed, they show up in your guacd install path, under the lib/freerdp directory. They need to be located somewhere where FreeRDP can find them - usually this is in your system library path under a freerdp directory (for example, for me using CentOS 7 64-bit, it is in /usr/lib64/freerdp). Either copy or link the guac*.so files from the guacd install directory to the FreeRDP plugin directory.- Depending on the browser, you may also need an extension or plugin to support this. I use Chrome, and use the Clipboard Permission Manager extension provided by Mike @ glyptodon.org. Due to security restrictions on Chrome, this extension is necessary to allow the seamless integration. I'm not certain about other browsers and their support for it, but I know Chrome requires it. -Nick
