Thank you. Please see the attached the text file for the full compilation
error(Guacamole Client).
Yes I am trying to install Guacamole natively , using the repo and following
the instructions in the user guide.
Guacamole server installation was successful. I used the guacamole-server
source from the Guacamole project web site and followed the build and
installation process outlined in the guide.
I obtained the guacamole client source from the project website and followed
the build process. This is where it fails. I am not using GitHub. Our
institution's security policy advises me not to use Github. I can ask for an
exception and use GitHub however I am wondering why the Client installation
would fail when I have all dependencies in place and haven't modified the
downloaded source. I would prefer to use the tested and evaluated code rather
than the untested GitHub source.
There is this note under the guacamole-client section in the user guide. Will
this work in my case, having built and installed the server?
If you do not want to build guacamole-client from source, just download
guacamole.war from the project web site, along with any desired extensions, and
skip ahead to Deploying
Guacamole<https://guacamole.apache.org/doc/gug/installing-guacamole.html#deploying-guacamole>.
Please advise. Many thanks

Hi Nick Thank you for responding to my query.
Just to let you know that I had run 'mvn package -e'.

There may be other failure messages that provide more clarity above this - this
looks like the end of the output, but there's generally other output above this
that indicates the cause of the compilation failure.

Are you making changes to the code - either changing existing code, or adding
other code? I think this message means exactly what it says - a Compilation
Failure - which means it has failed to compile something. Look in the error
messages above this, where the actual compilation failure occurs.
If you're changing code, you probably have a mistake in the code that needs to
be fixed. If you're not changing code and just trying to build from the
official repo, try cleaning out or deleting the local copy and checking out
from Github, again, to get a completely clean code.
