fast-java-dynamic-compiler

A library for IDEs and Code Editors to compile java projects faster dynamically.

Usage

Note that the project, that is to be compiled dynamically, must have already been compiled at least once!

All you need to do is call JavaDynamicCompiler.fastCompile.

package test;
import java.io.File;

import javax.tools.DiagnosticCollector;
import javax.tools.JavaFileObject;

import java.util.LinkedList;

import omegaui.dynamic.compiler.JavaDynamicCompiler;

public class DynamicCompilerTest {
	
	public static void main(String[] args){
		String projectPath = "/home/ubuntu/Documents/Omega Projects/Test Dynamic Compiler";

		LinkedList<File> files = new LinkedList<>();
		files.add(new File("/home/ubuntu/Documents/Omega Projects/Test Dynamic Compiler/src/test/TestFile.java"));
		files.add(new File("/home/ubuntu/Documents/Omega Projects/Test Dynamic Compiler/src/test/TestDependentFile.java"));

		String[] classpath = new String[]{"/home/ubuntu/Downloads/jediterm.jar", "/home/ubuntu/Downloads/dependency.jar"};
		
		DiagnosticCollector<JavaFileObject> diagnostics = JavaDynamicCompiler.fastCompile(projectPath, classpath, files);
		diagnostics.getDiagnostics().forEach(System.out::println);
	}
	
}

files is the list of files that have changed contents since last compilation, thus, recompiling only the changed files.

The above code will compile and generate the .class files in bin directory of the project.
