Are the Eclipse compiler and formatter available as stand-alone

If not why not?  Is it something to do with being big and blue?
Or do they not want their competitors using these components?

In one of our projects I've used the Eclipse compiler to compile a batch of Java files. This works perfectly. [Never used formatter stand-alone.]

You'll need the 'JDT Core' plugin: I've used org.eclipse.jdt.core_3.0.1, in particular the class org.eclipse.jdt.internal.compiler.batch.Main in jdtcore.jar. The following snippet shows how this class can be used


import org.eclipse.jdt.internal.compiler.batch.Main

/**
 * Compiles sourceFile and produces .class file in outDir.
 * @param sourceFile source file to compile
 * @param outDir directory of resulting class file
 * @return <code>true</code> if compilation was successful,
 *         <code>false</code> when compilation failed
 */
private boolean compileJavaSource(File sourceFile, File outDir)
{
  StringWriter javacOut = new StringWriter();
  PrintWriter pwJavacOut = new PrintWriter(javacOut);
  StringWriter javacErr = new StringWriter();
  PrintWriter pwJavacErr = new PrintWriter(javacErr);

  Main javac = new Main(pwJavacOut, pwJavacErr, false);

  String[] args = {"-d", outDir.toString(), sourceFile.toString()};

  boolean compiled = javac.compile(args);
  pwJavacOut.close();
  pwJavacErr.close();

  if (compiled)
  {
     // success
     return true;
  }
  else
  {
    // failed: log compiler messages
    __logger.severe("Java compiler stdout: " + javacOut.toString());
    __logger.severe("Java compiler stderr: " + javacErr.toString());
    return false;
  }
}
