The command used to invoke the language server is missing some options to include additional java modules. Without these modules the server was not working properly. The correct command can be found in a `launcher` script on the same directory the `java` executable for the language server is found. This commit changes the docs to prefer the launcher script over the java executable. For backward compatibility it also fixes the command invocation in case the java executable is configured.

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 launcher
|
|
executable in this directory.
|
|
|
|
g:ale_java_javalsp_executable *g:ale_java_javalsp_executable*
|
|
*b:ale_java_javalsp_executable*
|
|
Type: |String|
|
|
Default: `'launcher'`
|
|
|
|
This variable must be set to the absolute path of the language server launcher
|
|
executable. For example:
|
|
>
|
|
let g:ale_java_javalsp_executable=/java-language-server/dist/mac/bin/launcher
|
|
<
|
|
|
|
===============================================================================
|
|
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.
