How to Set Up Sublime Text 3 to Run and Compile Java on Linux

Setting Sublime Text 3 to run specific Java version

1. On Sublime Text 3, go to "Tools" > "Build System" > "New Build System..."
2. Paste the following piece of code. Edit the path setting accordingly. I'm using Zulu JDK.

{
    "cmd": ["javac", "$file_name", "&&", "java", "$file_base_name"],
    "selector": "source.java",
    "file_regex": "^\\s*File \"(...*)\", line ([0-9]*)",
    "path": "C:\\Program Files\\JDK-Zulu\\zulu-7\\bin",
    "shell": true
}

3. Save the setting with extension .sublime-build. I named mine Java7 Run.sublime-build.
4. After saving, it should appear in your Build System list. Select that and now when you Build, it will use Java 7 (or whatever Java version you set it to be).

To validate, you can use System.out.println(System.getProperty("java.version"));

Sublime Text 2 build system to compile & run Java in a new Terminal/Command Prompt window?

Here's the "polite" (read: short and readable) version of what I did to make this work.

• This is a starting point only. Full impl is a blog post, not an answer.
• Assumes: OS X, xterm, no package hierarchy, etc.
• Package/project stuff is relatively straight-forward, but IMO awkward.
• I don't have a complete solution that's cross-OS or that takes weird directories into account.
• My real version makes some assumptions that may or may not work for the rest of the world.
• My real version uses Ant or Maven, which solves many problems, but not all.
• Some of this can be wrapped up in the sublime-build file, but…
• …for me it's easier this way because of other stuff not shown here.

Nutshell (Simplification): compile and run through a shell script in order to get a new window.

Script

cd $1
/usr/bin/javac $2
/usr/X11/bin/xterm -e "/bin/bash -c \"/usr/bin/java $3; echo 'Press ENTER to quit...'; read line\""

JavaC.sublime-build

{
  "cmd": ["~/bin/run-java.sh $file_path $file $file_base_name"],
  "file_regex": "^(...*?):([0-9]*):?([0-9]*)",
  "path": "/usr/bin/java",
  "selector": "source.java",
  "shell": true
}

In real life it's a bit more complex.

All this said, I never really do anything with console input in Java proper; I do it via either a Groovy or JRuby REPL, or allow stubbing of input/output sources/destinations, or… but not in Java, and not from Sublime Text 2–I use an IDE for Java development. Anything else is a waste of my time, even for short, experimental stuff.
