Java Tools Plugin for Notepad++

This post and the plugin is outdated. Please use plugin from this link which is updated and allows customization of shortcut key mappings and much more.

Notepad++ is a great free editor. I like notepad++ because its a light weight editor and loads instantly. I use notepad++ for editing many files everyday. One plugin I always wanted was a plugin which lets me compile my java files and execute them from editor itself, but I couldn't find it so I wrote a myself. This plugin can be downloaded from this link.
I am working on this plugin to make it more effective, so that if user have more than one installations of JDK or JRE then user should be able to choose which one to use etc.
This is a simple plugin which has two commands-
Compile - compiles a java file.
Run - executes a java file.
For using this plugin Java must be installed on the system.


  1. Hey man thanks for this awesome plugin. I was wondering if there was a way to change the hot keys for the plugin though?

  2. In current plugin you cannot, but I am working on the same to provide functionality.

  4. Thanks for this, did you manage to add custom hotkeys?

  5. @AdenFlorian, well I am still working on that!!(as m busy with some other work..)

  6. @Cody Henderson, @Petri, @AdenFlorian : Please download the updated plugin from

  7. When I compile I get the error:
    The input line is too long.
    Press any key to continue . . .

    I have the most recent update. Thanks

  8. I had the same error at Win x64, and I found what path to JDK set incorrect in the file %temp%\nppjtcjf.bat "260 times the space and then \bin\javac.exe"
    For fix this I duplicate registry data from [HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit] to the [HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Development Kit]

  9. Thanks @Nickolay for locating the bug, currently I am very much busy with work and not able to update the plugin.
