Expected Results:
build success (and run)

Since language server is not in master it is not available as maven artifact. In that case you have to build the whole project (or build missing modules before building Che assembly).

[tanaka-takayoshi]

Thanks, but I got compilation error during building plugins https://github.com/eclipse/che#build-submodules

Is it a wrong step?

$ cd che/plugins
$ mvn clean install

Or is there no available step to use language server now?

[garagatyi]

Have you tried to build the whole project?

[tanaka-takayoshi]

I was thinking this step is to build whole project https://github.com/eclipse/che#build-submodules .
But it seems to be wrong.

[garagatyi]

The most full build is to call mvn clean install from che directory

[tanaka-takayoshi]

Thanks a lot, finally I succeeded in build and it works well. I note the steps and some hacks. (I'm afraid my steps are wrong because I extract from my all try and error.)

• install required tool

# yum install patch
(installing nodejs)
$ npm install -g bower
$ npm install -g gulp

• modify pom.xml due to reverse patch error

$ git diff
diff --git a/plugins/plugin-orion/che-plugin-orion-editor/pom.xml b/plugins/plugin-orion/che-plugin-orion-editor/pom.xml
index 2087b93..c4a0b63 100644

                 </executions>

• build with skip tests and some other steps

$ mvn clean install -DskipTests -Dfindbugs.skip -Dlicense.skip -Denforcer.skip  -Dmdep.analyze.skip
$ cd assembly/assembly-main/src/assembly/assembly-main
$ mvn install

[garagatyi]

I'm happy that you succeeded in building such a complex project. Maybe we should think about better documentation on typical errors and howto fix it. Especially because of some build-time dependencies such as node, etc.
@TylerJewell FYI

[TylerJewell]

Created a documentation issue for this. We used to have great docs for building the dashboard and all necessary plugins. But when we consolidated everything from different projects into a single project with subdirectories, looks like we lost some of the READMEs.

[chetanladdha]

I am not able to find 'devnation' branch. Does someone deleted it ?
Where I can see Xtext language server installed ?

[TylerJewell]

It's in master. We will share more details on checonf tomorrow.
