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 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.
