+To enable Java 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 folder |org.eclipse.jdt.ls.product/target/repository|.
+Ensure to set |g:ale_java_eclipselsp_path| to the absolute path of that folder.
+
+g:ale_java_eclipselsp_path *g:ale_java_eclipselsp_path*
