Horacio Sanson 5a8ba75265 Fix eclipse.jdt.ls workspace data path.
We were setting the -data parameter to the project root but this caused
the language server to fail initialization and synch of gradle
dependencies. As consequence ALE failed to work fully on gradle
projects.

This fix sets the workspace to the parent folder of the project root.
Normally this corresponds to the correct Eclipse workspace path.

When this is not the case, this fix also allows users to explicitly set
the absolute path to the workspace via configuration variable.

javalsp *ale-java-javalsp*
To enable Java LSP linter you need to download and build the vscode-javac
language server from https://github.com/georgewfraser/java-language-server.
Simply download the source code and then build a distribution:
scripts/link_mac.sh
or
scripts/link_windows.sh
This generates a dist/mac or dist/windows directory that contains the
language server. To let ALE use this language server you need to set the
g:ale_java_javalsp_executable variable to the absolute path of the java
executable in this directory.
g:ale_java_javalsp_executable *g:ale_java_javalsp_executable*
*b:ale_java_javalsp_executable*
Type: |String|
Default: `'java'`
This variable can be changed to use a different executable for java.
===============================================================================
eclipselsp *ale-java-eclipselsp*
To enable Eclipse LSP linter you need to clone and build the eclipse.jdt.ls
language server from https://github.com/eclipse/eclipse.jdt.ls. Simply
clone the source code repo and then build the plugin:
./mvnw clean verify
Note: currently, the build can only run when launched with JDK 8. JDK 9 or more
recent versions can be used to run the server though.
After build completes the files required to run the language server will be
located inside the repository folder `eclipse.jdt.ls`. Please ensure to set
|g:ale_java_eclipselsp_path| to the absolute path of that folder.
You could customize compiler options and code assists of the server.
Under your project folder, modify the file `.settings/org.eclipse.jdt.core.prefs`
with options presented at
https://help.eclipse.org/neon/topic/org.eclipse.jdt.doc.isv/reference/api/org/eclipse/jdt/core/JavaCore.html.
g:ale_java_eclipselsp_path *g:ale_java_eclipselsp_path*
*b:ale_java_eclipselsp_path*
Type: |String|
Default: `'$HOME/eclipse.jdt.ls'`
Absolute path to the location of the eclipse.jdt.ls repository folder. Or if
you have VSCode extension installed the absolute path to the VSCode extensions
folder (e.g. $HOME/.vscode/extensions/redhat.java-0.4x.0 in Linux).
g:ale_java_eclipselsp_executable *g:ale_java_eclipse_executable*
*b:ale_java_eclipse_executable*
Type: |String|
Default: `'java'`
This variable can be set to change the executable path used for java.
g:ale_java_eclipselsp_config_path *g:ale_java_eclipse_config_path*
*b:ale_java_eclipse_config_path*
Type: |String|
Default: `''`
Set this variable to change the configuration directory path used by
eclipselsp (e.g. `$HOME/.jdtls` in Linux).
By default ALE will attempt to use the configuration within the installation
directory.
This setting is particularly useful when eclipselsp is installed in a
non-writable directory like `/usr/share/java/jdtls`, as is the case when
installed via system package.
g:ale_java_eclipselsp_workspace_path *g:ale_java_eclipselsp_workspace_path*
*b:ale_java_eclipselsp_workspace_path*
Type: |String|
Default: `''`
If you have Eclipse installed is good idea to set this variable to the
absolute path of the Eclipse workspace. If not set this value will be set to
the parent folder of the project root.
