Rstudio: Installing RStudio from source: gwtc: "com.google.gwt.core.Core" missing

[KasperSkytte]

Hi!

When installing RStudio Desktop on Ubuntu Linux 18.04 from the GitHub source tree, I end up with the following error about a missing gwt module when running sudo make install:

Buildfile: /usr/local/src/rstudio/src/gwt/build.xml

ext:
   [jscomp] None of the files changed. Compilation skipped.

javac:
    [javac] Compiling 1 source file to /usr/local/src/rstudio/src/gwt/bin

gwtc:
     [java] Compiling module org.rstudio.studio.RStudio
     [java]    [ERROR] Hint: Check that your module inherits 'com.google.gwt.core.Core' either directly or indirectly (most often by inheriting module 'com.google.gwt.user.User')

I followed the instructions in INSTALL and dependencies/linux/README. The javac version is 10.0.1.

Here's exactly what I did:

git clone [email protected]:rstudio/rstudio.git
cd rstudio/dependencies/linux
./install-dependencies-debian
cd ../common
./install-common
cd ../../
mkdir build && cd build
cmake .. -DRSTUDIO_TARGET=Desktop -DCMAKE_BUILD_TYPE=Release
sudo make install

Output of cmake (success)

We have some known issues with the INSTALL file instructions, see #3061. At the moment, only supported way to get a working install is via make-package. We also have dockerfiles that can take care of all the dependencies and produce an installation package for you. See the docker-compile.sh script in the docker folder. Run it with no arguments to see usage instructions

Your issue may be due to having javac version 10.0.1 installed; per our wiki instructions https://github.com/rstudio/rstudio/wiki/Installing-RStudio-Dependencies we don't support Java 9 or 10. Sorry that the README is out of date in that regard. We currently have some redundant and out-of-date instructions between the README's and the wiki. I'll leave this issue open to track getting all of that back in sync.

Thank you. Simply running ./docker-compile.sh xenial-amd64 desktop to create a .deb file worked like a charm, even though Xenial is Ubuntu 16.04 and I'm using the new beaver, 18.04. So a little update of the installation instructions would be lovely.

Also, using an older java JDK version openjdk-8-jdk also solves the installation issues, but I have other programs that needs version 10, and I'm not an expert when it comes to having multiple versions of software installed at once.
