Java LSP in Sublime Text

We never end up with one software. Sublime Text 4 has been released some days ago, I try to find out a guideline to set up Java LSP. The purpose just for better reading and more freedom on Java projects (for example, I can use Go to definition).

Prerequisites

• LSP sublime package
• Java binary
• Eclipse jdtls, download here http://download.eclipse.org/jdtls/milestones/?d then decompress.

LSP Settings

Search LSP Settings, then apply below configuration to that file. This configuration is specified for Mac user.

// for MacOS

{ "clients": { "jdtls": { "command": [ "java", "--add-modules=ALL-SYSTEM", "--add-opens", "java.base/java.util=ALL-UNNAMED", "--add-opens", "java.base/java.lang=ALL-UNNAMED", "-Declipse.application=org.eclipse.jdt.ls.core.id1", "-Dosgi.bundles.defaultStartLevel=4", "-Declipse.product=org.eclipse.jdt.ls.core.product", "-Dfile.encoding=UTF-8", "-DwatchParentProcess=true", // false on windows, true other OSs "-Xmx1G", "-XX:+UseG1GC", "-XX:+UseStringDeduplication", "-jar", "<path_to>/jdt-language-server-1.1.2-202105191944/plugins/org.eclipse.equinox.launcher_1.6.100.v20201223-0822.jar", // 1. replace the PATH/TO with your own 2. replace * with the file version "-configuration", "<path_to>/jdt-language-server-1.1.2-202105191944/config_mac", // 1. replace the PATH/TO with your own 2. choose the config folder based on the OS "-data", "<replace_your_$TMPDIR_here>/T/<project_base_name>/jdt_ws" // replace <TEMP_DIR> with the temp folder in your system. macOS: echo $TMPDIR ], "enabled": true, "languageId": "java", "scopes": ["source.java"], "syntaxes": ["Packages/Java/Java.sublime-syntax"] } } } 

Enter fullscreen mode Exit fullscreen mode

// for Windows

{ "clients": { "jdtls": { "command": [ "java", "--add-modules=ALL-SYSTEM", "--add-opens", "java.base/java.util=ALL-UNNAMED", "--add-opens", "java.base/java.lang=ALL-UNNAMED", "-Declipse.application=org.eclipse.jdt.ls.core.id1", "-Dosgi.bundles.defaultStartLevel=4", "-Declipse.product=org.eclipse.jdt.ls.core.product", "-Dfile.encoding=UTF-8", "-DwatchParentProcess=false", // false on windows, true other OSs "-Xmx1G", "-XX:+UseG1GC", "-XX:+UseStringDeduplication", "-jar", "<path_to>\\jdt-language-server-1.1.2-202105191944\\plugins\\org.eclipse.equinox.launcher_1.6.100.v20201223-0822.jar", // 1. replace the PATH/TO with your own 2. replace * with the file version "-configuration", "<path_to>\\.lsp-tools\\jdt-language-server-1.1.2-202105191944\\config_win", // 1. replace the PATH/TO with your own 2. choose the config folder based on the OS "-data", "<path_to>\\.lsp-tools\\jdt_ws" // replace <TEMP_DIR> with the temp folder in your system. macOS: echo $TMPDIR ], "enabled": true, "languageId": "java", "scopes": ["source.java"], "syntaxes": ["Packages/Java/Java.sublime-syntax"] } } } 

Enter fullscreen mode Exit fullscreen mode

LSP Key Binding

For simple purpose, I just want to use Go to definition. Open LSP Key Binding then paste it

[ // Go To Definition { "command": "lsp_symbol_definition", "args": { "side_by_side": false }, "keys": [ "ctrl+d" ], "context": [ { "key": "lsp.session_with_capability", "operator": "equal", "operand": "definitionProvider" }, { "key": "auto_complete_visible", "operator": "equal", "operand": false } ] }, ] 

Enter fullscreen mode Exit fullscreen mode

Thanks to

To complete this setup, I have read some useful articles which help me figure out the right way to do.

• https://github.com/sublimelsp/LSP/issues/344
• https://forum.sublimetext.com/t/lsp-universal-language-server-plugin/30554/24
• https://lsp.readthedocs.io/en/latest/#java

Troubleshooting

By Cmd+Shift+P and search for “LSP”, you can see some kind of log panel to help you debug if something goes wrong.

It’s done. Happy coding!
