Remember, the argument is the name of the class that you want to use, not the filename. Here, your current directory is "C" again, and you are specifying a classpath of the current directory (C). Currently appcfg just looks for system properties which means that if is not invoked using a JRE that is within the SDK, it will fail to find javac.exe. Error Running Javac.exe Compiler User classes are found though the so-called user class path - a list of directories and JAR files which contain class files.
Still, this small configuration change solved the problem for me.

Alternatively, you can launch the class from any directory, provided that the $BASE_DIR is included in the CLASSPATH environment variable. P.S. http://tcsmacs.net/unable-to/java-io-ioexception-cannot-establish-proxy-connection-502-proxy-error.php Hence, the Java compiler and runtime must be informed about the location of the $BASE_DIR so as to locate the classes.
